Titan Usa TC20027 Screw Machine Drill Bit 27/64 in Carbide

Product Description

The TITAN USA TC20027 is a screw machine length drill bit designed for high-performance drilling in metal, composite, and hard materials. Built from solid carbide and featuring a 135-degree split point, this bit delivers fast penetration with minimal walking at the start of a cut. The shortened screw machine length body provides added rigidity compared to jobber-length bits, making it well-suited for applications where chatter and deflection must be controlled. With a bright uncoated finish and a 27/64-inch (0.4219 inch decimal) diameter, the TC20027 is a go-to choice for machinists, maintenance mechanics, and tool-and-die professionals who need consistent, repeatable hole quality.

This bit is intended for use in CNC machining centers, manual drill presses, and turret lathes where screw machine length bits are specified. The 135-degree split point reduces thrust force and eliminates the need for center-punching on most materials. The straight cylindrical shank accepts standard drill chucks across a wide range of machine types. It is most commonly used in production environments for drilling ferrous and non-ferrous metals, plastics, and other engineered materials where carbide tooling is required for hardness or heat resistance.

Key Features

• Solid carbide construction provides superior hardness and heat resistance compared to high-speed steel
• 135-degree split point reduces thrust force and self-centers without a pilot hole or center punch
• Screw machine length body increases rigidity and reduces deflection in tight-tolerance drilling
• Bright uncoated finish suitable for use with cutting fluids across a broad range of materials
• Regular spiral flute design promotes efficient chip evacuation during drilling
• Right-hand cutting direction compatible with standard drill press and CNC spindle rotation

Compatibility

Designed as a screw machine length replacement or production drill bit for use with standard straight-shank drill chucks in CNC machining centers, manual drill presses, and turret lathes. Fits any machine accepting a straight cylindrical shank in the 27/64-inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance professional familiar with carbide tooling. Always secure the shank fully in the chuck and verify runout before beginning a cut, as carbide is brittle and susceptible to breakage from misalignment or side loading. Power down and de-energize the machine before changing tooling. Use appropriate cutting fluid for the material being drilled to extend tool life and maintain hole quality.
