Titan Usa TC29016 1/4 in Carbide Drill Bit 135 Deg

Product Description

The TITAN USA TC29016 is a screw machine length drill bit engineered for high-performance drilling in tough materials. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, this bit handles heat and wear far better than standard high-speed steel tooling. It measures 0.2500 inches (1/4 inch, Letter E) in diameter, with a 135-degree split point for fast, accurate starts with minimal walking. The overall length is 2.5 inches, and the spiral flute length is 1.25 inches. Right-hand cutting with a straight cylindrical shank, it is suited for use in CNC machining centers, drill presses, and manual machine setups where consistent hole quality and tool life matter.

This bit is intended for machinists, tool and die professionals, and production shops working with hardened steels, stainless steel, cast iron, and other difficult-to-machine alloys. The screw machine (stub) length format offers increased rigidity compared to jobber-length bits, reducing deflection in short-reach drilling applications. The AlTiN coating raises surface hardness and oxidation resistance, making the bit effective at elevated cutting speeds and in dry or near-dry machining environments. Two spiral flutes promote efficient chip evacuation in both through-hole and blind-hole applications.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• AlTiN coating increases surface hardness and heat resistance at high cutting speeds
• 135-degree split point reduces thrust force and eliminates the need for a center punch
• Screw machine (stub) length body provides superior rigidity and reduced deflection
• Right-hand spiral flute design promotes efficient chip removal
• Straight cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed for use in CNC machining centers, drill presses, and manual lathes or mills accepting a 1/4 inch straight cylindrical shank. Suitable for drilling operations within the 0.2500 to 0.3000 inch decimal inch size range as noted in manufacturer specifications.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with carbide tooling requirements. Ensure the spindle and chuck are fully powered down before inserting or removing the bit. Carbide tooling is brittle and should not be subjected to impact or side-loading beyond the rated application. Follow machine tool manufacturer guidelines for recommended speeds and feeds when using carbide drill bits.
