Festool 200127 SM-KS Angle Transfer Device is a miter saw angle transfer accessory for trim and finish work. This is a angle transfer device designed for transferring inside and outside corner angles directly to a miter saw. Model Number: 200127. If you install crown, base, casing, or other finish material, this tool helps you get from corner measurement to cut setup without stopping to calculate or write down exact angles.

The big advantage here is speed with less guesswork. Festool states the SM-KS automatically generates the dissecting angle, which means the tool helps split the measured corner into the correct miter setting. In real use, that matters because it cuts out one of the most annoying parts of trim work: measuring a corner, translating it, and hoping nothing got lost between the wall and the saw.

It is built to work with interior and exterior angles, so it is useful in the spots where rooms stop being perfectly square and standard settings stop being reliable. That makes it a practical add-on for finish carpenters, remodelers, cabinet installers, and serious DIY users who want cleaner joints with less wasted stock.

Festool lists this accessory as suitable for the KS 60, KSC 60, and KS 120. The Tool Nut product data also notes a reflective center line intended to line up quickly with Kapex dual lasers. That gives you a fast visual reference at the saw and helps speed up setup when you are bouncing between multiple corners on an install.

Another useful point is that this accessory is not just about accuracy in a perfect shop environment. It solves a very jobsite problem: walking measurements back and forth without losing them. The locking design keeps the angle captured so the reading you take at the wall is the same one you bring to the saw. Less rework, less material waste, and fewer test cuts.

If you are the kind of user who cuts a few miters a year, this may feel like a specialty accessory. If you do finish work regularly, it is the kind of tool that earns its keep quickly. The value is not just in measuring corners. It is in making repeatable, reliable angle transfer faster when the job has to look right and the trim is too expensive to cut twice.
