Sharpening Disc for Tungsten Carbide Saws AWTools 125 mm (AW47510)

AWTools sharpening disc for tungsten carbide saws, 125 mm diameter, is designed to restore and maintain cutting edges on carbide-tipped circular saw blades. The disc is intended for use with bench grinders or dedicated sharpening machines that accept 125 mm wheels, providing controlled material removal to reshape and refine carbide tips. This tool supports regular workshop maintenance to improve cutting performance and extend blade service life.

Advantages

The AWTools disc provides consistent abrasion for tungsten carbide (widia) teeth, enabling uniform grind geometry across the blade circumference. Its 125 mm size fits many compact sharpening setups while offering sufficient surface area for stable contact during sharpening. The disc is suitable for frequent touch-ups as well as more substantial reprofiling, helping to reduce downtime and the need for blade replacement.

Suitable for

• Sharpening carbide-tipped circular saw blades
• Workshop blade maintenance and touch-ups
• Reprofiling worn or chipped carbide teeth
• Use with bench grinders and sharpening machines accepting 125 mm discs

Key specifications

• Disc diameter: 125 mm
• Intended material: tungsten carbide (widia) tips
• Application: grinding and sharpening of saw blade teeth
• Compatibility: machines and grinders with 125 mm disc mounting
• Typical use environment: workshop and industrial sharpening stations

How to use

Mount the sharpening disc securely on a grinder or sharpening machine designed for 125 mm wheels, following the machine manufacturer's mounting and safety instructions. Position the saw blade so that each carbide tooth contacts the disc at the correct grinding angle; make light, controlled passes to remove material evenly and avoid overheating the carbide. Check the tooth profile regularly and adjust contact pressure and angle as needed to achieve the desired geometry. After grinding, clean the blade and inspect for uniform edge condition before reinstallation.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and protective gloves. Allow the disc and blade to cool between passes to prevent thermal damage and use light, consistent pressure for even material removal. Verify machine speed and mounting are suitable for a 125 mm grinding disc and follow all safety guidelines from the equipment manufacturer.
