Titan Usa CD32602 Screw Machine Drill Bit 0.221 in Cobalt

Product Description

The TITAN USA CD32602 is a screw machine length drill bit designed for high-speed, close-tolerance drilling in metalworking and fabrication applications. Built from cobalt steel with a bright, uncoated finish, this bit handles tough materials including stainless steel, cast iron, and hard alloys without sacrificing edge life. The 135-degree split point reduces walking and allows drilling without a center punch on most surfaces. At 2.4375 inches overall length with a 1.3125-inch spiral flute, the screw machine format fits standard drill chucks and magnetic base drills where space is limited. Licensed machinists, tool and die technicians, and maintenance mechanics are the primary users of this drill geometry.

This bit is suited for production drilling in short-chucking applications where stub-length rigidity reduces deflection. Wire size 2 at 0.221 inches diameter places it in the 0.2000 to 0.2500 inch size range, covering common tapping prep and close-tolerance hole work in sheet metal, structural steel, and machined plate. The right-hand spiral flute provides efficient chip evacuation in both through-hole and blind-hole configurations. NAS 907 Type J specification compliance makes this bit appropriate for aerospace-adjacent and industrial maintenance environments.

Key Features

• Cobalt steel construction for extended tool life in hard and abrasive materials
• 135-degree split point reduces drill walk and lowers entry force
• Screw machine length at 2.4375 inches overall for rigid, low-deflection performance
• Right-hand, spiral-flute design promotes efficient chip removal
• Straight-cylindrical shank compatible with standard three-jaw chucks
• Meets NAS 907 Type J specification for heavy-duty industrial use

Compatibility

Designed as an OEM-style replacement drill bit fitting any standard drill chuck accepting a straight-cylindrical shank in the 0.2000 to 0.2500 inch size range.

Installation Notes

Installation is performed by qualified machinists or maintenance mechanics using a drill press, lathe, or handheld drill with a compatible three-jaw chuck. Ensure the chuck is fully tightened and the workpiece is securely clamped or fixtured before operation. Use appropriate cutting fluid for hard alloys and stainless steel to preserve edge life. Do not exceed the recommended feed rate for the material being drilled, and allow the split point to seat before applying full feed pressure.
