Titan Usa TC20119 Drill Bit Letter S Solid Carbide

Product Description

The TITAN USA TC20119 is a screw machine length drill bit sized to Letter S (0.3480 inches decimal equivalent), built from solid carbide for demanding drilling applications in metals, composites, and hard alloys. The 135-degree split point geometry reduces walking at entry and lowers thrust force, making it well suited for production environments where setup time and tool life matter. At 3 inches overall length and a flute length of 1.375 inches, this stub-length design provides added rigidity compared to jobber-length bits. The bright, uncoated finish means no coating thickness to account for in tight-tolerance holes. Weighing approximately 0.12 pounds, it is a lightweight yet durable tool for high-cycle use.

This drill bit is intended for use in CNC machining centers, drill presses, and hand-held power tools where a short, rigid cutting tool is preferred. Screw machine length bits are a standard choice in screw machine shops, production drilling, and any application requiring reduced deflection in shorter-reach setups. The straight cylindrical shank fits standard drill chucks and collet systems without additional tooling adapters. It is appropriate for use on steel, cast iron, aluminum, and similar workpiece materials where carbide tooling is specified.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 135-degree split point reduces drill walking and lowers entry thrust force
• Screw machine (stub) length at 3 inches OAL provides greater rigidity than jobber-length alternatives
• Regular spiral flute with 1.375-inch flute length promotes chip evacuation
• Bright uncoated finish suitable for applications where coating buildup is a concern
• Right-hand cutting direction with straight cylindrical shank for universal chuck compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit screw machine length drill bit for use in standard drill chucks and collet holders accepting straight cylindrical shanks in the Letter S size range.

Installation Notes

This tool should be installed and operated by qualified machinists or tool-and-die professionals familiar with carbide cutting tools. Ensure the drill chuck or collet is clean and properly tightened before operation, as carbide is brittle and sensitive to runout or side loading. Power down all equipment completely before changing tooling. Do not use impact-style drivers or hammer drills with this bit, as shock loading can fracture solid carbide.
