Titan Usa CS35020 Combo Drill Countersink Size 00 Hss Altin

Product Description

The TITAN USA CS35020 is a combination drill and countersink designed to perform two operations in a single pass: drilling a pilot hole and forming the countersink seat simultaneously. Built from high-speed steel with an AlTiN coating, this tool delivers heat and wear resistance suited to production drilling in ferrous and non-ferrous materials. It carries a trade size of 00, a body diameter of 0.125 inches, and a drill point diameter of 0.0250 inches. The included angle is 60 degrees and the drill point angle is 118 degrees. At 1.25 inches overall length, it fits standard drill press and CNC setups. Right-hand cutting direction with a plain cutting edge style.

This combo drill countersink is used in metalworking, machining, and fabrication environments where countersunk fastener seats or center-starting points are required. It is well-suited to light-duty work on steel, aluminum, and similar materials. The double end type extends tool life by offering two usable ends, making it a practical choice for high-cycle production work or bench operations where downtime for tool changes is a concern.

Key Features

• AlTiN coating provides elevated heat resistance and extended tool life compared to uncoated HSS
• Double end design provides two cutting ends per tool
• 60-degree included angle for standard countersink seat geometry
• 118-degree drill point angle for self-centering starts on metal
• Plain cutting edge style for clean, consistent results
• Right-hand cut for use with standard drill presses, lathes, and CNC spindles

Compatibility

Designed as an OEM-style replacement and standard trade-size 00 combo drill countersink for use in drill presses, lathes, and CNC machining centers accepting straight-shank tooling at 0.125 inch body diameter.

Installation Notes

This tool is typically installed by machinists, toolmakers, or fabricators in a drill press, lathe tailstock, or CNC spindle. Secure the tool firmly in the chuck or collet before operation and confirm the workpiece is clamped or fixtured to prevent movement. Power down all equipment before changing tooling. Follow applicable shop safety practices and machine manufacturer guidelines for spindle speed selection based on material type.
