Hertel 300-002008 Combo Drill Countersink Size 6 Solid Carbide

Product Description

The HERTEL 300-002008 is a solid carbide combo drill countersink designed to drill and countersink in a single pass. Trade size 6 with a 0.5-inch body diameter, a 7/32-inch drill point diameter, and a 7/32-inch point length, this tool is built for precision work in metalworking, fabrication, and light industrial applications. The 118-degree drill point angle and 82-degree included countersink angle are ground into a bright, uncoated solid carbide blank for clean, repeatable results. Right-hand cutting direction. Machinists and tool-and-die technicians are the primary users.

This combo drill countersink is suited for benchtop drill presses, CNC machining centers, and manual milling setups where a single tool needs to produce a pilot hole and countersink in one operation. The 3-inch overall length fits standard tool holders used in production and job-shop environments. The plain cutting edge style and double end type make it a practical choice for countersinking screw clearance holes in steel, aluminum, and similar materials where a clean seat for a flat-head fastener is required.

Key Features

Designed as an OEM-style replacement or direct-use solid carbide combo drill countersink for trade size 6 applications in standard drill press and CNC tool holders accepting a 0.5-inch body diameter shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with cutting tool setup. Secure the tool firmly in a collet or drill chuck rated for the body diameter before operation. Always bring the spindle to a full stop before changing or measuring the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain cut quality.
