Helical Solutions 83756 Drill Mill 3/8 Inch 4 Flute Solid Carbide

Product Description

The HELICAL SOLUTIONS 83756 is a solid carbide drill mill designed for combination drilling and milling operations in a single tool. With a 3/8 inch mill diameter and a 90-degree point angle, it handles spot drilling, chamfering, and end milling without a tool change. The 4-flute, right-hand flute geometry supports efficient chip evacuation and surface finish in a range of workpiece materials. A Tplus coating improves wear resistance and tool life compared to uncoated carbide. The 7/8 inch length of cut and 2.5 inch overall length suit it to short-reach applications in production and job-shop environments. Machinists and CNC operators install this tool in standard 3/8 inch toolholders.

This drill mill fits residential and commercial machine shop applications where consolidating operations reduces cycle time. It is suited for use in CNC machining centers and manual mills performing chamfer, countersink, and shallow pocket work. The 3/8 inch shank diameter matches standard ER collets and end mill holders common in most shops. It is part of the Helical Solutions Specialty Profiles Combination Chamfer and End Mills 4 Flute High Performance series, intended for demanding multi-operation setups.
