Titan Usa TC20255 Drill Bit Size 55 Solid Carbide 135 Deg

Product Description

The TITAN USA TC20255 is a screw machine length drill bit designed for precision drilling in tight-clearance applications. Built from solid carbide, this bit delivers the rigidity and heat resistance needed when drilling hard metals, plastics, and composites. The 135-degree split point geometry reduces walking on entry and minimizes the need for a center punch. At 1.5 inches overall length, the stub-style profile suits short-reach setups in drill presses, CNC machines, and handheld applications where a standard-length bit would overhang. Machining professionals and maintenance technicians rely on this geometry for clean, accurate holes in production and repair work.

This bit is suited for use in screw machine operations, CNC drilling, and general-purpose metalworking. Wire gauge size 55 corresponds to 0.0520 inches in decimal, placing it in the small-diameter range commonly used for tapping pilot holes, instrument machining, and light-gauge sheet metal work. The bright uncoated finish makes it appropriate for use with water-soluble or oil-based cutting fluids where coating adhesion is not required. It is sold individually and fits standard straight-shank chuck toolholders.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 135-degree split point reduces drill walk and improves entry accuracy
• Wire gauge size 55 (0.0520 inches) for small-diameter precision drilling
• 1.5-inch overall length suits short-reach and screw machine setups
• Bright uncoated finish compatible with most cutting fluids
• 2-flute regular spiral design for efficient chip evacuation

Compatibility

Designed as a direct-fit replacement for standard straight-shank screw machine length drill bits in wire gauge size 55. Fits any chuck toolholder accepting a straight cylindrical shank in the appropriate diameter range.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with small-diameter tooling. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in the chuck to prevent slippage, which can snap small-diameter carbide bits. Carbide is brittle compared to high-speed steel — avoid side loading or flexing the bit during use.
