شريط صنفرة من كربيد التنجستن، ناعم (قطر 1/2 بوصة × 1/2 بوصة)

I’ve been using this fine sanding band on some tight little curves and it’s held up way longer than the paper ones I used to buy. The tungsten carbide coating really does save you from having to swap bits every few minutes.

The heat resistance is a real plus when I'm shaping hard plastics—the band doesn't glaze over like regular abrasives do. It's actually outlasted three of my old sanding drums on similar work.

I was skeptical about durability, but this fine tungsten carbide band cuts through hardened steel pins without wearing down after several uses. Fits my standard rotary tool drum perfectly, though you need to buy the drum separately.
