Angle grinder accessory Proxxon 28729 — 8 cm diameter, compatible with Proxxon 37160 and KGS80

Proxxon 28729 is an 8 cm diameter cut-off wheel accessory designed for small angle grinders and compatible machines such as the Proxxon 37160 Chop and Mitre Saw KGS80. The wheel is a single-piece replacement supplied in black and is intended for precision cutting, light grinding and polishing of small workpieces in hobby, workshop and light professional environments. Constructed from aluminum oxide, it features a thin profile suitable for accurate cuts and a 10 mm bore to fit compatible shafts. The wheel is balanced for use up to its maximum rating of 10,000 rpm and is supplied one per package.

Advantages

The aluminum oxide composition provides durable abrasive performance on a range of materials including wood, steel, non-ferrous metals and plastics. Its 8 cm diameter and slim 1.6 mm thickness enable precise, narrow cuts with minimal material removal. The 10 mm bore is compatible with common small-angle-grinder and chop-saw spindles, allowing straightforward replacement and interchangeability. Rated to 10,000 rpm, the wheel is suitable for the speeds typical of compact Proxxon tools, offering consistent cutting action and predictable wear.
