Titan Usa TC79229 Carbide Jobber Drill Bit Size 29

Product Description

The TITAN USA TC79229 is a solid carbide jobber-length drill bit in wire gauge size 29 (0.1360 inches decimal), designed for precision hole-making in demanding metal-cutting applications. It features a 118-degree split point for self-centering entry and reduced thrust, and carries an ALTiN (aluminum titanium nitride) coating that improves heat resistance and tool life at higher cutting speeds. The two-flute spiral design with a regular helix promotes efficient chip evacuation. Overall length is 2.5 inches, with a 1.375-inch flute length and a straight cylindrical shank. This bit is sold individually and suits machinists, tool-and-die shops, and maintenance professionals working with harder workpiece materials.

The TC79229 is rated for drilling steel, stainless steel, cast iron, superalloys, and titanium — workpiece material codes P, M, K, and S. Its 10xD flute-to-diameter ratio supports drilling to a maximum depth of 1.375 inches. The straight cylindrical shank (0.1360 inches diameter, 1.125 inches long) fits standard drill chucks on benchtop drill presses, CNC machining centers, and hand-held power drills. It is intended for general-purpose drilling tasks where carbide hardness and coating performance are required over high-speed steel alternatives. Coolant-through capability is not included in this design.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS bits
• ALTiN coating enhances heat resistance and extends tool life in ferrous and exotic metals
• 118-degree split point reduces walking and lowers required feed force at drill entry
• Two-flute regular spiral promotes clean chip evacuation in through and blind holes
• Rated for steel, stainless steel, cast iron, superalloys, and titanium (P, M, K, S material codes)
• Straight cylindrical shank fits standard chucks without adapters

Compatibility

Designed for general-purpose drilling in steel, stainless steel, cast iron, superalloys, and titanium workpieces. Fits any standard drill chuck accepting a 0.1360-inch straight cylindrical shank. Part of the TITAN USA TC79 series of solid carbide jobber drill bits.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with cutting tool safety practices. Secure the shank fully in the chuck and verify concentricity before drilling. Do not exceed the rated maximum drilling depth of 1.375 inches without retracting the bit to clear chips. Coolant-through is not supported on this bit; apply external coolant or cutting fluid as appropriate for the workpiece material and speed.
