Hertel 300-002003 Combo Drill Countersink 1/8 in Solid Carbide

Product Description

The HERTEL 300-002003 is a solid carbide combination drill and countersink, Trade Size 1, designed for precision drilling and countersinking in a single operation. The tool features a 1/8 inch body diameter with a 3/64 inch drill point diameter and a 3/64 inch drill point length. Overall length is 1.5 inches, making it compact and suitable for close-tolerance work. The 82-degree included angle is the standard geometry for flat-head fastener seating in metal fabrication, machining, and toolroom applications. Right-hand cutting direction and a plain cutting edge style provide consistent, controlled material removal in ferrous and non-ferrous substrates.

This combo drill countersink is suited for light-duty machining centers, manual drill presses, and CNC applications where a small-diameter combination tool is needed. The solid carbide construction handles hard materials and delivers longer tool life compared to high-speed steel alternatives. It is commonly used by machinists, tool-and-die workers, and precision fabricators countersinking for flat-head screws or preparing center holes in small workpieces. The double end type extends usable tool life by providing two working ends.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 82-degree included angle matches standard flat-head fastener countersink geometry
• 3/64 inch drill point for precise center drilling and countersinking in one pass
• Right-hand cut with plain cutting edge for smooth, consistent material removal
• Double end type provides two usable cutting ends
• Compact 1.5 inch overall length suits tight workpiece setups

Compatibility

Designed as a standard Trade Size 1 combo drill countersink for use in drill presses, manual mills, and CNC machining centers accepting small-diameter combination tooling with an 82-degree countersink angle.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or toolroom personnel familiar with cutting tool setup and speeds and feeds selection. Secure the tool firmly in the appropriate collet or chuck before operation and verify runout is within acceptable limits. Always power down and lock out the spindle before changing or inspecting the tool. Do not exceed the recommended RPM range for the material being machined.
