Description
Fine cuts in non-ferrous metals and precision materials. The Proxxon HSS saw blade for the KS 115 is a 100-tooth fine-cut blade made from high-alloy special steel with a high proportion of tungsten, vanadium, and molybdenum — delivering an even grain structure, high hardness, and long service life. At 0.5mm kerf and 100 teeth, it produces clean, burr-free cuts in aluminum, brass, copper, PC boards, and plastics where coarser blades would tear or leave rough edges.

KS 115 Blade Guide — Which Blade for Which Job?
- HSS 100T (No. 28020) — this blade: Fine cuts in non-ferrous metals, PC boards, and plastics. Narrowest kerf (0.5mm) for minimal material loss.
- Carbide-Tipped 20T (No. 28017): General purpose cutting in wood and harder materials. Carbide tips for longer life on abrasive materials.
- Super-Cut 80T (No. 28014): Fine crosscuts in wood. Larger 2-9/32" diameter for deeper cuts.
- Diamond Blade D107 (No. 28012): Cutting glass, ceramic, tile, and stone. Diamond abrasive for hard, brittle materials.
Frequently Asked Questions
Why HSS instead of carbide for non-ferrous metals?
HSS (High Speed Steel) is preferred for non-ferrous metals like aluminum and brass because it can be ground to a sharper edge than carbide, producing cleaner cuts with less burring. Carbide is harder but more brittle — better suited for abrasive materials like hardwood and composites.
Can this blade cut steel?
No — this blade is designed for non-ferrous metals, PC boards, wood, and plastics. For steel cutting, use the fiber cut-off discs with a Micromot rotary tool instead.
What is the kerf width?
0.5mm (1/64") — one of the narrowest kerfs available for the KS 115, minimizing material waste on precision cuts.
