Solid Pilot Counterbore: 0.2561" Dia, 0.1261" Pilot, 3 Flutes MPN:5973200

Solid carbide pilot counterbores feature extreme wear resistance and strength making them ideal for demanding applications like machining high-strength metals like stainless steel or cast iron, where drill bits quickly dull. This particular counter bore is manufactured from solid carbide providing a durable material that will maintain its sharp edge even when facing tough materials repeatedly thus reducing downtime for tool replacement while minimizing chip build-up for uninterrupted cutting action through the entire operation's length. With dimensions of 0.2561-inch diameter, 0.1261-inch pilot diameter and three flutes, this counter bore offers superior balance allowing the user to cut accurately without excessive vibration while maintaining tight tolerances even when faced with hardened materials like carbide requiring precise positioning when being fitted in a larger hole. Its compact design allows easy mounting on various machining centers ensuring consistent production levels making it popular among metalworking industries involved in machining components such as bolts, nuts or bearings where counter-sinking requirements are essential for flush installations.
