Solid Pilot Counterbore: 3/8" Dia, 1/4" Pilot, 3 Flutes MPN:C91703

Solid carbide pilot counterbores are essential tools for engineers seeking accurate and precise holes in a range of applications. With their versatile 3/8 diameter, they can easily create clearance holes or countersink screw heads without damaging the surrounding material. The 1/4 pilot ensures precision by reducing wander during drilling, while the three flutes allow for efficient chip evacuation to prevent bogging down and overheating. Engineers using high-strength alloys, stainless steel, or other challenging materials will benefit from these solid carbide counterbores' ability to maintain sharp cutting edges and resist wear, providing unrivaled accuracy across diverse applications in aerospace, automotive, marine, and construction industries.
