0.2969" Cut Diam, 7/8" Flute Length, Solid Carbide Solid Counterbore MPN:25519

This solid carbide counterbore features a 0.2969inch cutting diameter to cut precise flat bottom holes for use with hardware such as screws or nuts without damaging threaded rods, while its 7/8 inch flute length offers efficient chip evacuation thus minimizing load and heat build-up allowing users greater control when drilling stainless steel, cast iron, aluminum, and other hard materials. A durable tool steel substrate ensures reduced vibration even on repeated use thus offering longer tool life and reduced downtime for engineers or technicians involved in machining operations where precision is key. Additionally, this counterbore can also be used as a porting drill when utilizing the included flute plug which prevents chips from entering critical cooling passages while boring internal surfaces; thus enhancing efficiency within manufacturing applications such as hydraulics or engines requiring precise machining techniques and superior finishes.
