Titan Usa CD32508 Cobalt Screw Machine Drill Bit 1/8 in

Product Description

The TITAN USA CD32508 is a screw machine length cobalt drill bit designed for high-speed drilling in tough materials where standard high-speed steel bits fall short. At 0.125 inches (1/8 inch) in diameter, this bit features a 135-degree split point that reduces walking and allows immediate bite without a center punch. The cobalt construction provides heat resistance and durability when drilling through stainless steel, hardened steel, cast iron, and other hard metals. With a bright, uncoated finish and straight-cylindrical shank, it fits standard drill chucks without adapters. Machinists, maintenance technicians, and metalworking tradespeople rely on this type of bit for production and repair drilling.

This bit is suited for use in drill presses, CNC machines, hand drills, and screw machines where a short, stiff cutting tool is required to maintain accuracy in shallow-hole applications. The reduced overall length of 1-7/8 inches compared to a jobber-length bit minimizes deflection during entry, making it a common choice in tight-tolerance metalworking environments. It meets NAS 907 Type J specifications, making it appropriate for aerospace and heavy industrial work requiring documented material standards.

Key Features

• Cobalt construction for heat resistance when drilling hard and abrasive metals
• 135-degree split point reduces bit walking and eliminates the need for center punching
• Screw machine (stub) length minimizes deflection for improved hole accuracy
• Right-hand spiral flute design for standard forward-rotation drilling
• Straight-cylindrical shank compatible with standard drill chucks
• Meets NAS 907 Type J specification for verified material and dimensional standards

Compatibility

Designed as an OEM-style replacement and standard-use cobalt stub drill bit for use in drill presses, screw machines, and hand drills accepting a 0.125 inch straight-cylindrical shank.

Installation Notes

Install in a properly rated drill chuck tightened securely before operation. Disconnect or de-energize the drill or machine before changing bits. Use cutting fluid or coolant when drilling hard metals to extend bit life, even though this bit does not feature through-coolant capability. Operate at speeds appropriate for the workpiece material and bit diameter per standard machining feeds-and-speeds references.
