Titan Usa CS10004 Combo Drill Countersink Size 4 Hss

Product Description

The TITAN USA CS10004 is a combination drill and countersink designed for creating pilot holes and countersunk seats in a single pass. Built from high-speed steel with a bright uncoated finish, this tool handles ferrous and non-ferrous metals, wood, and plastics in production and maintenance environments. The 5/16 inch body diameter accommodates a 1/8 inch drill point, and the 118-degree drill point angle suits general-purpose drilling on most common workpiece materials. The 60-degree included angle on the countersink portion produces a standard countersunk profile compatible with flat-head fasteners. Machinists, toolmakers, and maintenance technicians use this type of tool in drill presses, CNC lathes, and hand-held drilling equipment.

This combo drill countersink is suited for light to medium metalworking, woodworking, and fabrication applications where a combined drilling and countersinking operation saves tool changes and cycle time. It is appropriate for trade size 4 fastener preparation in both shop and field settings. The double-end design extends usable tool life by providing two working ends before the tool is retired. Right-hand cutting direction is standard for conventional spindle rotation in most drilling equipment.

Key Features

Compatibility

Designed as an OEM-style replacement or standard stock tool for trade size 4 combo drill countersink applications in drill presses, lathes, and compatible hand-held drilling equipment using 5/16 inch body shank tooling.

Installation Notes

This tool is installed by machinists and maintenance technicians in standard drill chucks or collet holders accepting a 5/16 inch body diameter. Secure the tool firmly before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Inspect the cutting edges before each use and replace or regrind when wear is visible to avoid workpiece damage. Follow applicable shop safety standards and use appropriate personal protective equipment when operating drilling equipment.
