Why choose it

The cobalt-alloyed high-speed steel provides enhanced heat resistance and wear resistance, making this reamer suitable for tough materials and extended production runs. Its straight flutes ensure smooth chip evacuation and consistent hole quality.

Ideal use cases

• Reaming taper pin holes in tool and die making
• Preparing holes for standard taper pins in mechanical assemblies
• Maintenance and repair of machinery requiring precise tapered fits

Good to know

The bright finish reduces friction and improves corrosion resistance. The reamer is designed for use with a suitable tap wrench or machine holder. Always use cutting fluid for best results.
