Titan Usa CS35004 Combo Drill Countersink Size 4 Hss

Product Description

The TITAN USA CS35004 is a combination drill and countersink designed for single-step drilling and countersinking operations in metal, wood, and composite materials. Built from high-speed steel with an aluminum titanium nitride (AlTiN) coating, this tool delivers extended wear resistance and heat tolerance during high-speed machining. The body measures 5/16 inches in diameter with a 1/8-inch drill point diameter and an overall length of 2-1/8 inches. The 118-degree drill point angle and 60-degree included angle make it well suited for standard fastener seat preparation. It is sized for trade size 4 applications and cuts in a right-hand direction.

This combo drill countersink is used in metalworking, fabrication, and general machining applications where preparing a countersunk seat for flat-head fasteners is required in a single pass. It is appropriate for use in drill presses, CNC machines, and hand-held drilling equipment. The plain cutting edge style and double end type make it a practical choice for production environments and job-site use alike. Machinists, fabricators, and skilled tradespeople working with ferrous and non-ferrous metals are the primary installers of this tool.

Key Features

• High-speed steel construction provides durability and toughness across a range of workpiece materials
• AlTiN coating improves heat resistance and extends tool life at elevated cutting speeds
• 118-degree drill point angle suited for standard metal drilling applications
• 60-degree included angle prepares correct seat geometry for flat-head fasteners
• Double end type allows use of both ends, extending usable tool life
• Right-hand cutting direction compatible with standard drill chucks and spindles

Compatibility

Designed as an OEM-style replacement or direct-use combo drill countersink for trade size 4 applications requiring a 5/16-inch body diameter and 1/8-inch drill point diameter.

Installation Notes

This tool is intended for use by machinists and fabricators operating drill presses, lathes, milling machines, or handheld power drills. Secure the workpiece firmly before operation to prevent movement during drilling. Ensure the drill chuck or collet is properly tightened to the correct shank diameter before running the spindle. Always use appropriate cutting fluid or lubricant when machining ferrous metals to reduce heat buildup and prolong tool life.
