Hertel 300-003008 Combo Drill Countersink Size 6 Solid Carbide

Product Description

The HERTEL 300-003008 is a solid carbide combination drill countersink designed to drill and countersink in a single operation. Built to trade size 6 with a 1/2 inch body diameter, it produces a 90-degree included angle countersink using a plain cutting edge in a right-hand cut direction. The bright polished finish reduces friction and chip buildup during cutting. At 3 inches overall length with a 7/32 inch drill point diameter and 7/32 inch point length, this tool is suited for precision work in metalworking, fabrication, and machining applications. It is installed and operated by machinists, tool and die workers, and metal fabrication professionals.

This combo drill countersink is used in production and maintenance machining environments where countersinking for flat-head fasteners must be performed accurately and efficiently. The double end type and 118-degree drill point angle make it effective on steel, aluminum, and similar materials. It is not an aircraft-style tool and is not a long-length or tapered design. Typical applications include creating flush-mount screw seats in structural components, panels, and fabricated assemblies.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 90-degree included angle for standard flat-head fastener countersinks
• 118-degree drill point angle for clean entry and accurate hole placement
• Bright polished finish reduces friction and aids chip evacuation
• Right-hand cut, plain cutting edge for conventional CNC and manual machine use
• Double end type extends usable tool life

Compatibility

Designed as an OEM-style replacement and production tooling option for standard trade size 6 combination drill countersink applications in metalworking and fabrication setups.

Installation Notes

This tool is intended for use by machinists and metalworking professionals in drill presses, CNC machining centers, or manual lathes. Secure the workpiece fully before operation and confirm the spindle speed is appropriate for the material and tool diameter. Inspect the cutting edges before each use and replace the tool if chipping or wear is detected. Solid carbide tools are brittle and should not be subjected to side loading or dropped on hard surfaces.
