The Festool 577280 AB-AS CS/TKS Dust Extraction Hose Set is a dust extraction hose set built to connect both the blade guard and the machine body to a single mobile extractor. This is a dust extraction hose set designed for low-dust cutting on trimming saws and table saws. Model Number 577280. If you are running a Festool saw that throws dust from more than one outlet, this setup solves a real problem: one extractor, two pickup points, and a cleaner work area.

What makes this set useful is the way Festool split the job between two hose sizes instead of asking one hose to handle everything. You get a D 27 x 2.0 m antistatic suction hose, a D 36 x 1.0 m antistatic suction hose, and a Y terminal. That matters because the machine port and the guard port do not always want the same hose size. With this setup, each connection is matched more appropriately, which helps airflow and makes routing around the saw less awkward.

On the job, that means better chip and dust capture both above and below the cut line. On underfloor trimming saws and bench-mounted circular saws, debris does not come from just one place. The guard catches part of it and the lower machine housing throws the rest. The whole point of the AB-AS CS/TKS set is to collect from both points at the same time, so cleanup is lighter and visibility around the cut stays better.

Festool also built this set with an antistatic design. That is not filler. If you have used standard hoses around fine dust, you already know static can make dust cling to the hose and can make the hose itself more annoying to handle. Antistatic construction helps reduce that static charging from dust and chips, which is especially helpful in longer cutting sessions or in cleaner indoor work.

From a design standpoint, this is a purpose-built accessory, not a generic hose bundle. The total hose length is listed as 3 meters, and the diameter range is given as 27 to 36 mm, or about 1-1/16 in to 1-3/8 in. The included Y terminal is what makes the system practical, because it brings the two hose runs back to one extractor connection without needing a homemade workaround. For users already invested in Festool dust extraction, that is the difference between a setup you actually use and one that stays on the shelf.

Compatibility is a big part of the value here. Festool lists this set as suitable for CT mobile dust extractors, and it is intended for saw applications including the CS 50, CS 70, and TKS 80. It can also be used with trimming saws and table saws more broadly where the machine and guard both need extraction. If your saw only has one pickup point, this is probably more kit than you need. If your saw throws dust from two points, this is the right kind of fix.

Who should buy it? This is for woodworkers, finish carpenters, shop users, and serious DIY buyers who care about dust control enough to set the saw up correctly the first time. It is especially useful for indoor cutting, remodeling spaces, cabinet work, and any job where less airborne dust and less cleanup matter. Bottom line: if you are already using a Festool CT extractor with a compatible saw, this hose set makes that extractor system work the way it should.
