METRIC TYPE 3620 - FOUR SPIRAL FLUTES - STRAIGHT SHANK - FOR NON-FERROUS & CAST IRON
TYPE
Carbide tips brazed to hardened tool steel bodies. Right spiral flutes with 118° included chamfer angle.
Core drills, with increased flute capacity, remove more material from a cored or cast hole than a reamer. This often eliminates a final reaming or boring operation. Specifically designed for cast iron, non-ferrous and high temperature alloy applications. For steel applications refer to Type 3621 and Type 3623.
Below is Lexington Cutter's selection of Core Drills. We offer a wide variety of carbide tipped and solid carbide cutting tools. Over 95% are in stock either finished or semi finished for fast delivery.
Tool and shank diameter tolerances: +.000"/-.001".
