Diamond Core Drill Bit OD .695” ID .40” Drill Depth 4.5" Thread 3/4"-16 

Heavy Wall Diamond Core Drill – Sintered (Metal Bond) | Made in USA

This heavy wall sintered (metal bond) diamond core drill is designed for drilling hard, dense, and abrasive materials where high strength, rigidity, and long tool life are required. The thick wall construction provides increased stability and resistance to deflection, making it well suited for applications involving higher loads, deeper holes, and challenging materials.

The sintered metal bond matrix securely holds the diamond abrasive, allowing controlled wear and consistent cutting performance throughout the life of the tool. This design delivers predictable results, good hole geometry, and extended service life in both laboratory and production environments. The tool can be used for drilling holes or extracting core samples.
