Titan Usa TC20252 Size 52 Solid Carbide Screw Machine Drill Bit

Product Description

The TITAN USA TC20252 is a solid carbide screw machine length drill bit designed for precision drilling in tight-clearance applications. Built to Series 200 standards, this bit features a 135-degree split point that reduces walking and allows drilling without a center punch on most materials. The straight cylindrical shank fits standard drill chucks and collets. At 0.0635 inches (wire size 52) in diameter with a 1.5-inch overall length, this compact bit is well suited for high-speed drilling in hard or abrasive materials where high-speed steel bits wear prematurely. The bright, uncoated finish is appropriate for use with cutting fluids.

This drill bit is used in production machining, toolroom work, and precision fabrication where small-diameter, close-tolerance holes are required. Screw machine length bits are shorter than jobber-length bits, which reduces deflection and improves hole accuracy in CNC machining centers, turret lathes, screw machines, and bench drill presses. The solid carbide construction makes this bit a strong choice when working with hard plastics, composites, cast iron, or other materials that demand wear resistance.

Key Features

• Solid carbide construction for superior wear resistance in hard and abrasive materials
• 135-degree split point reduces thrust and minimizes drill walking
• Screw machine (stub) length reduces deflection for improved hole accuracy
• Regular spiral, 2-flute design promotes chip evacuation in through-hole applications
• Bright uncoated finish compatible with water-soluble and oil-based cutting fluids
• Straight cylindrical shank fits standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard drill chucks and collets accepting straight cylindrical shanks in the 0.0635-inch diameter range.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or toolroom technician. Secure the shank fully in the chuck or collet before applying power, and confirm the spindle speed is appropriate for the material and diameter being drilled. Always apply cutting fluid where recommended to extend tool life and maintain hole quality. Inspect the bit for chipping or wear before each use, as solid carbide is rigid and can fracture if subjected to side loading or excessive feed pressure.
