0.500″ – 2.750″ (shank mounted) stock Core Drills
Our Metal Bond 0.500″ – 2.750″ (shank mounted) stock Core Drills are engineered with an exclusive high-strength metal bond developed for exceptional durability, consistent cutting performance, and long tool life. Designed for straight, clean hole drilling in today’s most demanding engineered and brittle materials, these core drills significantly reduce chipping, cracking, drill burn-out, and premature wear.
Available in standard sizes from 0.500″ to 2.750″, these tools can also be custom-manufactured to your exact ID, OD, wall thickness, bond hardness, and diamond grit requirements. We offer precision mounting solutions to match your machine interface or existing facility standards.
