Bosch 10 Expert C470 Best for Wood and Paint hiomapaperit 320 karkeus

The Bosch Expert C470 sanding sheets are designed for professional-grade fine sanding on wood, paint, varnish, filler, and primer. With a 320 grit size, these sheets deliver a very fine finish, making them ideal for intermediate sanding and surface preparation. The open-coated aluminium oxide abrasive ensures high material removal and a long lifespan, while the hook-and-loop fastening system allows quick and easy attachment to orbital sanders or hand sanding blocks. Each pack contains 10 sheets measuring 93 x 186 mm with 8 optimized dust extraction holes.

Advantages

These sanding sheets offer exceptional durability and consistent performance. The semi-friable aluminium oxide grain self-sharpens during use, maintaining cutting efficiency. The synthetic resin bonding provides strong adhesion to the paper backing, reducing shedding. The open-coat design prevents clogging, even when sanding paint or varnish. Users benefit from reduced downtime and a superior surface finish.
