Titan Usa TC79101 Solid Carbide Jobber Drill Letter B

Product Description

The TITAN USA TC79101 is a solid carbide jobber-length drill bit in Letter B size (0.2340 inches decimal), designed for high-productivity drilling in demanding materials. The bit features a 118-degree split point for self-centering entry and reduced thrust, paired with an ALTiN (Aluminum Titanium Nitride) coating that extends tool life at elevated cutting temperatures. With a regular spiral flute and right-hand cutting direction, this drill is suited for machinists, tool-and-die tradespeople, and production floor operators who need consistent hole quality in ferrous and hard-to-machine materials.

The TC79101 is engineered for drilling steel, stainless steel, cast iron, superalloys, and titanium — workpiece material codes P, M, K, and S. Its 9xD flute-to-diameter ratio and 2.0-inch maximum drilling depth make it a practical choice for through-holes and moderate-depth blind holes in CNC machining centers, drill presses, and manual lathes in both job-shop and production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• ALTiN coating improves heat resistance and extends tool life in steel and stainless steel applications
• 118-degree split point reduces walking and lowers drilling thrust
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Straight-cylindrical shank (0.2340 inches diameter) compatible with standard drill chucks and collet holders
• 2.0-inch flute length supports a maximum drilling depth of 2.0 inches

Compatibility

Designed as a general-purpose OEM-style solid carbide jobber drill in the TITAN USA TC79 Series, suitable for use in any standard drill chuck or collet system accepting a 15/64-inch straight shank.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or tool-setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Use the correct collet size or chuck jaw setting to secure the straight shank without runout. Solid carbide tooling is brittle — avoid side-loading or interrupted cuts beyond the tool's rated capacity, and do not exceed recommended feed and speed parameters for the workpiece material.
