Good fit if…
- Your weekly work is finish carpentry: interior casing, base, and nested crown on a portable sliding compound miter saw that plugs into ordinary North American 120 volt / 60 Hz service.
- You can feed a 13 amp saw and already have a way to carry and stage about 52 lb (the instruction-manual EPTA weight), not a cabinet saw that never leaves the shop.
- You will treat dust collection as a separate purchase. The manual tells you to connect a mobile dust extractor; a 1-7/16 inch (36 mm) hose is the size it recommends. A Festool CT extractor is not assumed and does not ship in this saw's box.
- You will open the live Amazon listing and confirm part 575306 -- the US 120 volt KAPEX KS 120 REB -- not the 230 volt sibling sold under part 575302.
Avoid if…
- The main job is framing, decking, or rough construction lumber. This article evaluates a finish-trim sliding miter, not a framing saw.
- Your power is 230 volt / 50 Hz European service, or the listing you are about to buy shows model 575302. That is a different machine.
- You expected a dust extractor, hose kit, or "up to 91 percent capture" to arrive in the same carton as the saw.
- You need production sawing of steel, concrete, or mineral materials. The manual's intended use is wood, plastic, and similar materials; special Festool blades exist for limited unhardened ferrous and non-ferrous metal, which is not a reason to buy this as a metal-cutting station.
- You will not recheck ASIN B07XS93BT7 and part 575306 on the live page.
What you are actually buying
The machine in this checklist is Festool's KAPEX KS 120 REB, part 575306, Amazon ASIN B07XS93BT7. Festool USA lists that part as the 120 VAC, 1 600 W US saw. The saved instruction manual 717270_E (dated 31 August 2023) specifies the KS 120 REB at 13 A, idle speed 1400 to 3600 rpm, a 10-1/4 inch (260 mm) blade with a 1-3/16 inch (30 mm) bore, and says that in North America only Festool machines marked 120 V / 60 Hz may be used.
Do not confuse it with Amazon listing B07KZSCNBF, whose title and model field have pointed at part 575302 and 230 volts. That sibling is outside this article. If the live page no longer shows 575306, stop and walk away from this checklist.
Buyer Checkpoint has not cut trim on this saw. Capacities below come from the instruction manual and the dated Amazon page, not from a jobsite test.
Weight, crown figures, and other conflicts worth reading before you buy
Several published weights describe the same KS 120 REB. The instruction manual lists 52 lb (24 kg) according to EPTA-Procedure 01:2014. Festool USA's product table has used 50.93 lb (24.3 kg). Marketing copy has said "47 pounds." The dated Amazon item-weight field read 57.3 lb, which we treat as a packaged or shipping figure, not net tool weight. For carrying and staging, plan around the official table plus the manual's 52 lb EPTA figure, and leave extra margin if you will move the saw in its carton.
Cutting envelopes are not a single magic number. The manual's table for maximum workpiece height by width without extra extensions lists about 3-1/2 by 12-1/64 inches at 0°/0°, 3-1/2 by 8-1/2 inches at 45° horizontal / 0° vertical, and smaller envelopes when both axes are at 45°. A separate special cutting position is documented for trimming slats up to 4-3/4 inches (120 mm) tall. Finish carpenters often shop this saw for nested crown; treat any nested-crown figure on Festool USA's 575306 page as manufacturer marketing for that page, and do not let it overwrite the manual's height-by-width table when you check a cut.
Dust collection is a system, not a feature that arrives with the handle. The manual warns about dust and tells you to connect a mobile dust extractor. In the same dust-extraction section it recommends a 1-7/16 inch (36 mm) hose because of how chips collect. Festool USA product notes for 575306 describe high capture only with a matching 27/36 mm extractor hose. None of that means a CT vacuum is in the carton.
Buyer Checkpoint Fit score
Fit 93/100 for a finish carpenter or trim installer who needs a portable 120 volt, 13 amp sliding compound miter for interior trim and nested-crown work, and who does not already assume a Festool extractor is owned. This score is not raised just to fill a publishing slot.
Method: Buyer Checkpoint Fit score for the target buyer profile on the 30/25/20/15/10 framework (Use-case & safety / Documented capability / Integration / Ownership / Supporting evidence). A hard stop for that profile overrides the total. Wrong profiles are described under “Avoid if…” without a second numeric score. See the public scoring method.
| Checkpoint | Points | Why this score |
|---|---|---|
| Use-case & safety | 28 / 30 | Interior trim and finish carpentry on a portable 120 volt sliding miter is a clear use, and the manual's intended materials match that shop. Points stay off 30 because a framer, a 230 volt buyer, or someone who needed a dust extractor in the same box can still order the wrong tool. |
| Documented capability | 23 / 25 | 13 A, 1400 to 3600 rpm, the 10-1/4 inch blade, the height-by-width table, and the special slat position are written in the instruction manual. Weight-line conflicts and the gap between marketing crown copy and the manual table keep this row from 25. No hands-on cut is claimed. |
| Integration | 20 / 20 | Ordinary 120 volt / 60 Hz service and a 13 amp draw are the documented electrical path. Remaining friction is staging about 52 lb plus buying and routing a matching extractor hose; the saw is portable, not plug-and-forget without that plan. |
| Ownership | 13 / 15 | The saw itself is a single portable station. Blades, a mobile extractor, and hose are extra. Those extras are normal for this class and are disclosed rather than hidden. |
| Supporting evidence | 9 / 10 | A November 9, 2026 recheck at delivery ZIP 10001 showed a buyable featured offer with Add to Cart visible on ASIN B07XS93BT7, with the title showing part 575306. Manual 717270_E backs the electrical and capacity figures used here. Evidence stays at 9 because this was not a cutting test and published weights still disagree. This row does not freeze a price, a rating, or a review count. |
Total: 28 + 23 + 20 + 13 + 9 = 93. Framing as the main job, 230 volt / 575302 power, expecting an extractor in the box, or skipping the live part-number check is a hard stop for this profile and overrides the 93.
Buying facts that change the decision
| Checkpoint | What the documents say | Why it matters |
|---|---|---|
| Exact US part | 575306 on the dated Amazon title and on Festool USA's 120 VAC page. | 575302 is the 230 volt sibling. Confirm 575306 before you buy. |
| Electrical | Manual: 13 A, 120 V / 60 Hz only in North America. Festool USA: 120 VAC, 1 600 W. | You need a circuit that can feed 13 A. This is not the EU-voltage KAPEX. |
| Blade | 10-1/4 inch (260 mm) diameter, 3/32 inch (2.5 mm) cutting width, 1-3/16 inch (30 mm) bore, chip angle 0° or less. | Replacement blades have to match those numbers, not a generic 10 inch miter blade. |
| Speed | Idle speed 1400 to 3600 rpm, with a speed-adjusting wheel on the saw. | Useful across trim woods and plastics; the manual warns that defective electronics can remove smooth start-up or speed control. |
| 0°/0° envelope | About 3-1/2 × 12-1/64 inches (88 × 305 mm) without extra extensions. | This is the manual table, not a brochure shortcut. |
| Special slat position | Trimming slats up to 4-3/4 inches (120 mm). | A documented extra position, separate from the main height-by-width table. |
| Weight | Manual 52 lb EPTA; Festool USA table 50.93 lb; marketing "47 pounds"; dated Amazon item weight 57.3 lb. | Plan the carry around official net figures and extra carton weight. Do not pretend the lines agree. |
| Dust | Connect a mobile dust extractor; 36 mm hose recommended in the manual; US notes mention a 27/36 mm extractor hose. | Budget the extractor separately. Do not score this saw as if a CT vacuum were included. |
| Intended materials | Wood, plastic, and similar materials. Special blades can handle limited unhardened ferrous and non-ferrous metal. | Not a production metal or masonry saw. |
How to confirm the live listing without trusting a dated note
Open ASIN B07XS93BT7 and read the part number in the title and in the model field. You want 575306 and a 120 volt description. If you see 575302, a 230 volt line, or a Spanish title that belongs to the sibling listing, this checklist no longer applies.
Then confirm the current seller, shipper, and price on that same page. A November 9, 2026 recheck at delivery ZIP 10001 showed a featured, in-stock offer with Add to Cart visible. That check is not a promise that the same seller or price will be there when you buy. Adding the saw to your cart does not reserve it and does not lock a price.
Who should buy -- and who should walk away
Buy this KAPEX if you already live on interior trim, you have a working 120 volt path for a 13 amp sliding miter, you can stage about 52 lb, and you will buy dust collection separately. Walk away if your work is framing, if your power is the 230 volt sibling, if you thought the extractor shipped in the crate, or if you will not re-read part 575306 on the live Amazon page.
Stock preparation is a separate purchase. If boards still need flattening and edge-squaring in the shop before they reach the saw, that is stationary work covered in our Powermatic 54HH helical jointer checklist. Resawing thick lumber belongs to a bandsaw such as the one in our JET JWBS-18SFX 18-inch resaw checklist, not to a sliding miter.
Festool KAPEX KS 120 REB verdict in brief
Each line below stands on its own and names its source date. None of it comes from a hands-on test.
- The Festool KAPEX KS 120 REB, part 575306, is a finish-trim buy only on North American 120 V / 60 Hz service, because Festool instruction manual 717270_E (31 August 2023) rates it at 13 A and allows only machines marked 120 V / 60 Hz in North America.
- Part 575302 is not a cheaper version of the US KAPEX: Festool USA lists 575306 as the 120 VAC, 1 600 W saw, and the separate Amazon listing B07KZSCNBF has pointed at the 230 volt 575302 sibling.
- Plan to carry the KAPEX KS 120 REB at about 52 lb, the EPTA weight in manual 717270_E (31 August 2023), rather than the 47 pound marketing line or the 57.3 lb Amazon item weight, which reads as a packaged figure.
- A dust extractor is a separate purchase for the KS 120 REB: manual 717270_E (31 August 2023) tells owners to connect a mobile dust extractor and recommends a 1-7/16 inch (36 mm) hose.
- For checking a cut, the KS 120 REB manual table (31 August 2023) of about 3-1/2 by 12-1/64 inches at 0°/0° outranks any nested-crown marketing figure.
- On 9 November 2026, Amazon ASIN B07XS93BT7 still showed part 575306 in its title, with a featured, in-stock offer and Add to Cart visible at delivery ZIP 10001.

FAQ
What is the Festool KAPEX KS 120 REB in this article?
It is Festool's sliding compound miter saw, part 575306, Amazon ASIN B07XS93BT7. The instruction manual 717270_E rates the KS 120 REB at 13 A, idle speed 1400 to 3600 rpm, a 10-1/4 inch (260 mm) blade, and about 52 lb EPTA, and allows North American use only on 120 V / 60 Hz. Buyer Checkpoint did not cut material on this saw.
Is this the same as part 575302?
No. Part 575302 appears on a separate Amazon listing as a 230 volt machine. This checklist evaluates only 575306. If the live page shows 575302, stop.
Does a dust extractor come in the box?
No. The manual tells you to connect a mobile dust extractor and recommends a 1-7/16 inch (36 mm) hose. Festool USA notes describe capture with a matching 27/36 mm extractor hose. A CT vacuum is a separate purchase.
Which cutting capacity should I trust?
Use the instruction-manual table: about 3-1/2 by 12-1/64 inches at 0 degrees / 0 degrees, with smaller envelopes at 45 degrees, plus a special slat position up to 4-3/4 inches (120 mm). Treat any nested-crown figure on Festool USA's page as marketing for that page, not as a replacement for the manual table.
Why do published weights disagree?
The manual lists 52 lb EPTA. Festool USA's table has used 50.93 lb. Marketing copy has said 47 pounds. The dated Amazon item weight read 57.3 lb, treated here as packaged or shipping weight. Plan the carry around the official net figures plus carton margin.
What are the hard stops?
Framing as the main job; 230 volt service or part 575302; expecting an extractor in the crate; production metal or masonry work; or skipping the live 575306 check.
Sources and research limits
- Festool instruction manual 717270_E for the KS 120 REB, revision dated 31 August 2023: electrical ratings, EPTA weight, blade data, intended use, North America 120 V / 60 Hz note, workpiece table, special slat position, and dust-extraction hose guidance.
- Festool USA product page for part 575306 (KS 120 REB USA): 120 VAC / 1 600 W identity used to separate this saw from 575302.
- Amazon listing ASIN B07XS93BT7, live-page check dated 7 November 2026: featured offer, in-stock state, visible Add to Cart, title showing 575306. Rechecked 9 November 2026 with delivery ZIP 10001: title still showing part 575306, featured in-stock offer, Add to Cart visible (not clicked). Seller and price were recorded internally and are not frozen here.
- Amazon sibling ASIN B07KZSCNBF was reviewed only far enough to reject it as the 230 volt / 575302 listing and is not evaluated as a buy.
Buyer Checkpoint did not cut material on this saw and did not time dust capture. Limits of the documents -- disagreeing weights, marketing crown copy versus the manual table, and dust capture that depends on a separate extractor -- are left visible instead of being averaged away.
