Extra-Fine Rubber Abrasive for Final Finishing
Unlike hard vitrified stones, CRATEX wheels use a resilient rubber-bonded abrasive matrix that delivers: Ammunition for Sale+2Brownells Norge+2
Controlled, chatter-free cutting that’s forgiving on edges and corners
Very smooth, refined surface finishes – great before bluing, coating, or final polish
Minimal tendency to gouge, even on small or delicate parts
The 000 extra-fine grit on this #74 wheel is tailored for final blending and polishing, not heavy stock removal. It’s the step you use after coarse and medium abrasives, when surface quality matters more than speed. Brownells+2Ammunition for Sale+2
#74 Straight Edge – 7/8" x 1/8" for Precision Control
The #74 straight-edge profile gives you a flat, predictable contact surface that’s ideal when you need precise control on flats, edges, and narrow surfaces: Brownells UK+2Brownells Norge+2
7/8" diameter is small enough for close work, yet large enough to stay stable at speed
1/8" thickness lets you get into tight spaces, grooves, and shoulders other wheels can’t reach
Straight-edge design is great for maintaining flat surfaces and crisp lines
This makes WHEELS 190025744 especially useful for carefully refining edges on slides, frames, and small machined components where accuracy and surface quality both matter.
1/16" Arbor Hole – Built for Gunsmith Mandrels & Rotary Tools
With a 1/16" arbor hole, the #74 Ex-Fine wheel is designed to mount on 1/16" arbor mandrels, commonly used in gunsmithing and precision work. Brownells Norge+2Crow Wholesale+2
Typical setups include:
High-speed rotary tools and flex-shaft systems with 1/16" wheel mandrels
Bench motors configured with small-arbor adapters
Gunsmith polishing stations where CRATEX wheels and mandrels are standard tooling
Once mounted properly, the wheel runs concentrically, giving you a smooth, vibration-resistant feel that lets you “feather” pressure and control your finish.
