Titan Usa TC29207 Screw Machine Drill Bit Size 7 Carbide

Product Description

The TITAN USA TC29207 is a screw machine length drill bit designed for high-performance drilling in metals, composites, and hard materials. Built from solid carbide and coated with AlTiN (aluminum titanium nitride), this bit handles elevated cutting temperatures without sacrificing edge integrity. The 135-degree split point reduces walking on entry, allowing accurate starts without a center punch in many applications. At 2.5 inches overall length, the stub-style body provides rigidity and minimizes deflection in tight setups. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. Machinists, tool and die technicians, and maintenance professionals rely on this geometry for consistent, repeatable holes in demanding production and repair environments.

This bit suits CNC machining centers, drill presses, and hand-held power tools where a compact overall length improves rigidity and control. Wire size 7 corresponds to a decimal diameter of 0.2010 inches, placing it in the 0.2000 to 0.2500 inch range. It is well suited for precision hole work in steel, stainless, cast iron, aluminum, and similar materials where tool life and dimensional accuracy matter. The two-flute spiral configuration evacuates chips efficiently in both through-hole and blind-hole drilling scenarios.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS
• AlTiN coating provides high-heat resistance and extends tool life in ferrous and hard materials
• 135-degree split point reduces thrust force and minimizes bit walking on entry
• Screw machine (stub) length of 2.5 inches overall delivers added rigidity and reduced deflection
• Straight-cylindrical shank compatible with standard three-jaw chucks and collet holders
• Two-flute spiral design promotes efficient chip evacuation in production drilling

Compatibility

Designed as an OEM-style replacement and standard tooling option for any drill press, machining center, or hand drill accepting a straight-cylindrical shank bit in the 0.2010-inch diameter range. Part of the TITAN USA Series 201 screw machine drill bit line.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the power source is locked out before inserting or removing the bit. Seat the shank fully into the chuck or collet and verify runout before beginning a cut. Solid carbide bits are brittle compared to HSS and should not be used at feed rates or side loads that risk snapping the shank.
