Titan Usa TC20110 Drill Bit Letter J Solid Carbide 135 Deg

Product Description

The TITAN USA TC20110 is a screw machine length drill bit sized to Letter J (0.2770 inches decimal equivalent), manufactured from solid carbide with a bright uncoated finish. The 135-degree split point geometry reduces walking on entry and lowers thrust requirements, making it well suited for production drilling in harder materials. At 2.5 inches overall length, the stub-length design provides added rigidity compared to jobber-length bits, reducing deflection during high-cycle operations. The two-flute regular spiral configuration promotes efficient chip evacuation. This bit is installed and used by machinists, tool and die workers, and maintenance professionals working in metal fabrication and industrial settings.

The TC20110 is designed for screw machine operations and general-purpose drilling in ferrous and non-ferrous metals, including steel, cast iron, aluminum, and similar materials. Its stub-length profile makes it a common choice for drill press and CNC machining center applications where rigidity and hole accuracy are priorities. The 1.25-inch flute length accommodates typical screw machine depth requirements without excess overhang.

Key Features

• Letter J size — 0.2770 inches decimal equivalent, within the 0.2500 to 0.3000 inch size range
• Solid carbide construction for hardness and wear resistance in demanding materials
• 135-degree split point reduces thrust and minimizes bit walking on entry
• Screw machine (stub) length at 2.5 inches OAL increases rigidity and reduces deflection
• Two-flute regular spiral design for efficient chip evacuation
• Right-hand cutting direction, straight cylindrical shank for standard chuck compatibility

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide screw machine drill bit for use in standard straight-shank drill chucks on drill presses, lathes, and CNC machining centers accepting bits in the 0.2500 to 0.3000 inch size range.

Installation Notes

Installation of drill bits should be performed by qualified machinists or toolroom personnel following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight shank firmly in a properly sized collet or drill chuck to the depth recommended by the machine manufacturer. Inspect the bit for chips or cracks before each use, as solid carbide is brittle and should not be subjected to side loads or interrupted cuts beyond its rated capability.
