Product Description
The GP Spotting Drill is a solid carbide drill built for fast penetration and accurate, high-quality holes. Manufactured from premium ultra-fine grain tungsten carbide, it combines high hardness with the toughness needed for consistent, chatter-free cutting and a superior surface finish. It is optimized for machining mold steel.
A rigid solid-carbide body minimizes deflection while the optimized point geometry self-centers for accurate hole position and roundness. Polished, high-capacity flutes clear chips quickly to prevent packing, and the wear-resistant coating maintains performance hole after hole.
Key Features
- Solid carbide body delivers rigid, accurate hole-making with minimal deflection
- Optimized point geometry centers instantly and reduces thrust
- Polished flutes promote fast, reliable chip evacuation
- Heat- and wear-resistant coating extends life in demanding materials
Applications
Ideal for hole-making in CNC machining centers and drilling operations. MSU Tools also manufactures custom geometries, coatings and dimensions to suit your specific material and application — contact our engineering team to discuss your requirements.
