Titan Usa TC20243 Drill Bit Size 43 Solid Carbide 135 Deg

Product Description

The TITAN USA TC20243 is a screw machine length drill bit designed for precision drilling in metal, plastics, and other hard materials. Built from solid carbide, it delivers exceptional hardness and wear resistance compared to high-speed steel alternatives. The 135-degree split point reduces walking on entry and requires less thrust to penetrate the workpiece. At 1.5 inches overall length with a 0.5-inch flute length, this stub-length geometry provides added rigidity, making it well suited for drilling in tight spaces or on short-travel spindles. The bright uncoated finish is compatible with a wide range of cutting fluids. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this bit.

This drill bit is sized at No. 43 wire gauge, equivalent to 0.0890 inches in diameter. It is intended for use in screw machines, CNC machining centers, drill presses, and hand-operated equipment where stub-length rigidity is preferred. The straight cylindrical shank fits standard drill chucks without adapters. Its compact length makes it a common choice for tapping prep holes, through-holes in thin stock, and precision location work where deflection must be minimized.

Key Features

• Solid carbide construction for extended tool life in abrasive and hard materials
• 135-degree split point for reduced thrust and self-centering on entry
• Screw machine (stub) length at 1.5 inches OAL for maximum rigidity
• 0.0890 inch diameter, No. 43 wire gauge sizing
• Right-hand cutting with regular spiral flute for efficient chip evacuation
• Bright uncoated finish compatible with most cutting lubricants

Compatibility

Designed as an OEM-style replacement or standard tooling addition for screw machines, CNC lathes, and drill presses accepting straight cylindrical shank drill bits in the 0.0000 to 0.1000 inch diameter range.

Installation Notes

This bit should be installed and tightened securely in a compatible drill chuck or collet before operation. Power down and lock out the machine before changing tooling, per standard OSHA lockout/tagout procedures. Solid carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without adequate support, or dropping the bit, as chipping or fracture can result. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish.
