Hertel 300-001008 Combo Drill Countersink 1/2 Inch Solid Carbide

Product Description

The HERTEL 300-001008 is a combination drill and countersink designed for precise drilling and countersinking in a single operation. Built from solid carbide with a bright, uncoated finish, this tool delivers the hardness and wear resistance needed for production machining and fabrication work. It features a 1/2 inch body diameter, a 7/32 inch drill point diameter, and a 60-degree included angle. At 3 inches overall length, the 300-001008 is a compact, rigid tool suited for machinists, toolroom technicians, and metal fabricators working with ferrous and non-ferrous materials.

This combo drill countersink handles countersinking operations in standard machine shop, aerospace supplier, and general metalworking environments. The plain cutting edge style and right-hand cut make it compatible with conventional CNC machining centers, manual mills, and drill presses. Trade size 6 designation makes it straightforward to spec for countersunk fastener applications. The double end type extends tool life by providing two usable cutting ends, reducing per-hole tooling cost in production runs.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom personnel familiar with cutting tool safety. Secure the tool firmly in a compatible collet or drill chuck rated for the shank diameter before operation. Inspect the cutting edges for chips or wear before each use, and never run a damaged carbide tool. Follow machine manufacturer guidelines for spindle speed and feed rate appropriate to the workpiece material.
