Titan Usa TC20246 Drill Bit Size 46 Solid Carbide

Product Description

The TITAN USA TC20246 is a screw machine length drill bit engineered for precision drilling in tight spaces and high-cycle production environments. Built from solid carbide, this bit delivers superior hardness and heat resistance compared to high-speed steel alternatives. The 135-degree split point geometry reduces thrust force and enables self-centering on entry, minimizing the need for a center punch. At 1.5 inches overall length, the stub-length body provides added rigidity and reduces deflection during drilling. The bright uncoated finish suits applications where coating compatibility or material reactivity is a concern. Intended for use by machinists, toolroom technicians, and fabricators working with ferrous and non-ferrous materials.

This bit is sized at wire gauge No. 46, with a decimal diameter of 0.0810 inches, placing it in the small-diameter range commonly used for tapping pilot holes, instrument components, precision fastener clearance holes, and detail work in tight tolerances. The 0.5-inch flute length accommodates chips effectively within the short overall body. The straight cylindrical shank seats in standard drill chucks without requiring a collet adapter. Typical applications include production drilling on drill presses, CNC machining centers, and hand-held power tools where a rigid, accurate small-diameter hole is required.

Key Features

• Solid carbide construction for extended tool life in demanding materials
• 135-degree split point for self-centering entry and reduced thrust
• Wire gauge No. 46 diameter — 0.0810 inches decimal equivalent
• 1.5-inch overall length (screw machine / stub length) for maximum rigidity
• 0.5-inch flute length with regular spiral for efficient chip evacuation
• Bright uncoated finish — no coating interaction with sensitive workpiece materials
• Right-hand cutting, straight cylindrical shank, 2-flute design

Compatibility

Designed as a screw machine length replacement or production drill bit for use in standard drill chucks and collet systems accepting a straight cylindrical shank at 0.0810 inches diameter in the Series 200 product line.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with small-diameter carbide tooling. Carbide is brittle — avoid lateral loading, interrupted cuts without proper feed control, or dropping the bit, as chipping or fracture can result. Secure the shank fully in the chuck or collet before operation and confirm runout is within tolerance for the application. Always power down and de-energize the machine before changing tooling.
