100-pk, 5 mm (3/16") Norton SGA Industrial Chainsaw Sharpening Grinding Stone Bits

100 bits pack

Norton Saint-Gobain Asia quality product

Keep chainsaw cutter links and curved steel edges cutting cleanly with these commercial-grade 5.0 mm mounted grinding stones. The vitrified aluminum oxide abrasive is precision-formed for fast, controlled sharpening on rotary tools, while the 3.0 mm (1/8 in.) straight shank helps maintain stable concentric rotation during repeated service work.

Pros

• Purpose-Matched Working Diameter: The 5.0 mm profile provides a balanced contact area for common medium chainsaw cutters and similar rounded cutting edges, helping restore cutter geometry without removing unnecessary material.
• Vitrified Aluminum Oxide Cut: Premium abrasive grain removes hardened steel efficiently and resists loading when used with light pressure and proper tool speed.
• Stable Rotary Tool Fit: The straight 3.0 mm (1/8 in.) shank fits standard rotary-tool collets and supports smooth, controlled sharpening with reduced chatter.
