Titan Usa TC20226 Screw Machine Drill Bit Size 26

Product Description

The TITAN USA TC20226 is a screw machine length drill bit built for precision drilling in tight-clearance and high-production environments. Manufactured from solid carbide, this bit delivers superior hardness and heat resistance compared to high-speed steel alternatives. It features a 135-degree split point that reduces walking and allows drilling to begin without a center punch on most materials. The overall length is 2 inches, the flute length is 0.875 inches, and the decimal diameter is 0.1470 inches (wire gauge size 26). The right-hand spiral flute design provides efficient chip evacuation. This bit is sold individually and is sized for applications requiring tight diameter tolerances.

This screw machine length drill bit is suited for metalworking, machining, and fabrication operations where a shorter, more rigid bit is required to reduce deflection. The stub length makes it a practical choice for drill press work, CNC machining centers, and manual machine shop operations. The bright uncoated finish means it can be used as-is or recoated after sharpening. It is typically installed by machinists, tool-and-die professionals, and trade technicians performing precision hole work in metal components.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 135-degree split point reduces thrust force and eliminates drill walk
• Screw machine (stub) length at 2 inches OAL provides increased rigidity and reduced deflection
• Right-hand cutting with regular spiral flute for efficient chip removal
• Bright uncoated finish compatible with most cutting fluids and re-sharpening workflows
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-style replacement or direct-fit screw machine length drill bit for use in standard straight-shank drill chucks and collets accepting a 0.1470-inch diameter shank.

Installation Notes

This drill bit is installed by machinists and metalworking tradespeople using standard drill chucks, collets, or CNC tool holders. Ensure the spindle is fully stopped and locked before changing tooling. Secure the shank fully in the chuck or collet to the correct engagement depth to prevent slippage during operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
