Titan Usa TC79203 Jobber Drill No.3 Solid Carbide Altin

Product Description

The TITAN USA TC79203 is a solid carbide jobber-length drill bit sized to No. 3 wire gauge (0.2130 inches diameter) and built for high-productivity drilling in demanding materials. The bit features an ALTiN (aluminum titanium nitride) coating, which raises surface hardness and heat resistance compared to uncoated carbide, making it well-suited for dry or near-dry cutting conditions. The 118-degree split-point geometry reduces walking at entry and lowers thrust force, allowing clean, accurate hole starts without a center punch. Overall length is 3 inches with a 1.75-inch spiral flute and a straight-cylindrical shank. Two regular-spiral flutes evacuate chips efficiently during through-hole and blind-hole operations.

This bit is rated for general-purpose drilling in steel, stainless steel, cast iron, superalloys, and titanium alloys, corresponding to ISO material codes P, M, K, and S. The 8xD flute-to-diameter ratio and 1.75-inch maximum drilling depth make it practical for typical production and maintenance drilling operations. It is sold as a single bit per package and is appropriate for use in machining centers, drill presses, and hand-held industrial drilling equipment where a straight-shank carbide bit is required. Machinists, tool-and-die workers, and maintenance technicians working with hard or abrasive workpiece materials will find it directly applicable to daily production tasks.

Key Features

• Solid carbide construction resists wear in abrasive and hard-to-machine materials including stainless steel and superalloys
• ALTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions
• 118-degree split-point tip self-centers on entry, reducing drift without a pilot hole
• Two regular-spiral flutes provide efficient chip evacuation in both through and blind holes
• Straight-cylindrical shank fits standard drill chucks without adapters
• 8xD flute-to-diameter ratio balances rigidity with adequate flute length for most common stock thicknesses

Compatibility

Designed as a general-purpose jobber drill for use in machining centers, CNC drill presses, and manual drilling equipment accepting a 0.2130-inch straight-cylindrical shank. Suitable for workpiece materials classified under ISO codes P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium).

Installation Notes

Install in a drill chuck or collet rated for straight-shank tooling and tighten securely before operation. Verify spindle runout is within acceptable tolerance before drilling superalloys or stainless steel, as excess runout accelerates carbide chipping. Solid carbide is brittle compared to high-speed steel — avoid side loading and interrupted cuts where possible. Follow shop safety practices and applicable OSHA machine-guarding requirements when operating drilling equipment.
