The Festool 203150 General Purpose 60-Tooth and Fine 80-Tooth Kapex KS 120 Blade Set is a two-blade miter saw blade set built for the Festool KAPEX KS 120. This is a miter saw blade set designed for clean wood cutting, trim work, crosscutting, and finish work on a Kapex saw. Model Number: 203150. If you already own a KAPEX and want the right blade ready for both everyday cutting and cleaner finish passes, this set makes that easy.

Festool includes two distinct blades here for a reason. The 60-tooth blade is the general purpose option for wood and soft plastics, and it is also suited for fine rip cuts where you want a cleaner joint. The 80-tooth blade is the finer crosscut blade for smoother results in veneered plywood, melamine, sheet goods, and both hard and soft woods. Instead of trying to force one blade to do everything, this set lets you match the blade to the material and the cut quality you need.

Both blades share the same core dimensions: 260 mm diameter, 2.5 mm kerf, 30 mm arbor, and a negative 5 degree hook angle with alternate top bevel tooth geometry. In practical terms, that gives you a blade package tuned for a sliding compound miter saw where cut control and surface finish matter more than brute feed speed. The thin kerf helps the saw cut with less resistance, which can improve efficiency and reduce waste, especially when you're making repeated cuts in finished stock.

One of the more important details is the oversized 30 mm arbor. Festool calls this out because a more secure blade mounting helps reduce vibration at the saw. Less vibration usually means a steadier cut and better surface finish, which is exactly what you want when you're cutting casing, trim, cabinet parts, veneered panels, or other stock that shows every mistake.

The materials and grind are aimed squarely at wood cutting and wood-based sheet goods, with added usefulness for soft plastics. The 80-tooth blade is the one you reach for when chip-out control is the priority. The 60-tooth blade is the better everyday choice when you want a balance of cut speed and finish quality. That makes this set especially useful for users who move between rougher jobsite production work and cleaner interior finish work.

This set is specifically compatible with the Festool KAPEX KS 120, so it is a direct match for that saw rather than a generic circular saw blade bundle. If you run a Kapex regularly, having both the universal and fine-tooth options on hand saves time and keeps you from compromising cut quality just because the wrong blade is mounted.

Who should buy it? Woodworkers, trim carpenters, remodelers, installers, and serious DIY users who already own a KAPEX KS 120 and want the saw to perform the way it should. If you're mostly cutting framing lumber, this is probably more blade than you need. If you're cutting finish materials, sheet goods, melamine, trim, and visible parts, this is the smart setup.

A smart Kapex upgrade if you care about cut quality

The Festool 203150 General Purpose 60-Tooth and Fine 80-Tooth Kapex KS 120 Blade Set gives Kapex owners the two blades most people actually need: one for daily work and one for cleaner finish cuts.

• Who it's for: Kapex KS 120 owners doing trim, cabinetry, finish carpentry, sheet goods, and other visible-cut work.
• Why it stands out: You get both a 60-tooth universal blade and an 80-tooth fine blade, plus the 30 mm arbor and thin kerf design that help the saw cut smoothly and accurately.
• Worth knowing: This set makes the most sense if you already own the KAPEX KS 120. It is a purpose-built blade set, not a general fit option for every miter saw on the rack.

• What saw is this blade set made for? It is designed for the Festool KAPEX KS 120.
• What is the difference between the two blades? The 60-tooth blade is the general purpose option for wood and soft plastics, while the 80-tooth blade is meant for smoother crosscuts in veneered plywood, melamine, sheet goods, and hardwood or softwood.
• What size are the blades? Both blades are 260 mm in diameter with a 2.5 mm kerf and a 30 mm arbor.
• What tooth geometry do these blades use? Both blades use alternate top bevel tooth configuration with a negative 5 degree hook angle.
