Titan Usa TC20013 Screw Machine Drill Bit 13/64 Solid Carbide

Product Description

The TITAN USA TC20013 is a screw machine length drill bit designed for high-precision, short-hole drilling in metal and hard materials. Built from solid carbide, it delivers superior hardness and heat resistance compared to high-speed steel alternatives. The 135-degree split point geometry reduces walking and allows drilling without a center punch on most surfaces. At 2.5 inches overall length with a 1.125-inch flute length, this stub-length bit offers increased rigidity and reduced deflection, making it well suited for CNC machining centers, drill presses, and production environments where hole location accuracy matters.

This bit is intended for use in production machining, metal fabrication, and precision drilling applications. The straight cylindrical shank fits standard drill chucks without adapters. The bright uncoated finish means it runs without the added friction of a coating, which suits shops that prefer regrinding bits in-house. It is appropriate for ferrous and non-ferrous metals, plastics, and composites. Machinists, tool-and-die technicians, and maintenance professionals working with tight tolerances will find the stub length and carbide construction particularly useful in applications where longer bits flex or chatter.

Key Features

• Solid carbide construction for superior wear resistance and rigidity in hard materials
• 135-degree split point reduces thrust force and minimizes walking on entry
• Screw machine (stub) length at 2.5 inches OAL provides maximum rigidity and minimal deflection
• Regular spiral flute design promotes efficient chip evacuation
• Bright uncoated finish allows for easy resharpening and visual wear inspection
• Right-hand cutting direction compatible with standard drill chucks and CNC spindles

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any drill chuck or CNC tool holder accepting a straight cylindrical shank in the 13/64-inch diameter range. Fits within the 0.2000 to 0.2500 decimal inch drill bit size range per Series 200 specifications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck, or a CNC tool holder with appropriate collet. Ensure the spindle is fully stopped and locked out before inserting or removing the bit. Verify chuck jaws are clean and free of chips to prevent runout. Do not exceed the recommended feed and speed parameters for the workpiece material and bit diameter.
