Titan Usa TC20239 Screw Machine Drill Bit Size 39

Product Description

The TITAN USA TC20239 is a screw machine length drill bit designed for precision drilling in compact, high-torque applications. Built from solid carbide, it delivers superior hardness and wear resistance compared to high-speed steel alternatives. The 135-degree split point geometry reduces walking and thrust force at entry, making it well suited for drilling into hard or tough materials without a center punch. With an overall length of 2 inches and a flute length of 0.625 inches, this stub-length bit provides added rigidity that minimizes deflection during drilling operations. The wire gauge size 39 corresponds to 0.0995 inches in decimal. Sold individually with no minimum order beyond a single unit.

This bit is used in machine shop, production, and field service environments where short-length rigidity is required. Screw machine length bits are a standard choice for drill press, CNC, and hand-held power tool applications where hole location accuracy and bit stability are critical. The straight cylindrical shank seats directly into standard chucks without adapters. The bright uncoated finish is appropriate for use with cutting fluids and suits a broad range of ferrous and non-ferrous base materials common in precision machining work.

Key Features

• Solid carbide construction for extended tool life in hard or abrasive materials
• 135-degree split point reduces thrust and eliminates walking at drill entry
• Screw machine length body provides maximum rigidity and minimal deflection
• Wire gauge size 39 (0.0995 inches) for precision-diameter holes
• Regular spiral flute with 0.625-inch flute length promotes efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• Bright uncoated finish compatible with cutting fluids and coolant-assisted drilling

Compatibility

Designed as an OEM-style replacement and standard-use screw machine length drill bit for any drill press, CNC machine, or hand-held power tool equipped with a standard straight-shank chuck capable of accepting a 0.0995-inch diameter bit.

Installation Notes

Installation and use of carbide drill bits should be performed by a machinist or qualified trades professional familiar with cutting tool safety. Secure the straight shank fully in the chuck and verify concentricity before operating. Solid carbide is brittle — avoid side loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Use appropriate cutting fluid or coolant when material and application call for it to extend tool life and maintain hole quality.
