Titan Usa TC79012 Carbide Jobber Drill Bit 3/16 in

Product Description

The TITAN USA TC79012 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. The bit features an ALTiN (Aluminum Titanium Nitride) coating that extends tool life by reducing heat buildup and improving wear resistance at elevated cutting temperatures. It carries a 118-degree split point for fast, self-centering penetration with reduced thrust. With an overall length of 2.75 inches and a 3/16-inch diameter, this bit suits precise drilling operations where carbide rigidity is required. It is typically installed and used by machinists, maintenance technicians, and tool-and-die professionals working in metalworking environments.

The TC79012 is engineered for drilling steel, stainless steel, cast iron, superalloys, and titanium — workpiece material categories classified under ISO codes P, M, K, and S. Its regular spiral flute geometry and right-hand cutting direction make it compatible with standard drill presses, CNC machining centers, and handheld power tools running appropriate RPM and feed rates for carbide tooling. The 9xD flute-to-diameter ratio provides adequate chip clearance for the depth range this jobber-length bit is designed to handle. It is a general-purpose grade drill suited for production and maintenance drilling across metal fabrication and repair applications.

Key Features

• Solid carbide construction provides rigidity and heat resistance superior to high-speed steel in hard and abrasive materials
• ALTiN coating improves oxidation resistance and extends bit life in dry or semi-dry cutting conditions
• 118-degree split point reduces walking and axial thrust, improving hole location accuracy
• Right-hand, regular spiral flute design ensures efficient chip evacuation in standard drilling setups
• Straight-cylindrical shank with 3/16-inch diameter fits standard drill chucks without an adapter
• No coolant-through requirement simplifies use in conventional drill press and handheld applications

Compatibility

Designed for use in steel, stainless steel, cast iron, superalloys, and titanium workpieces. Compatible with standard drill chucks and CNC tool holders accepting a 3/16-inch straight-cylindrical shank. Part of the TITAN USA TC79 series general-purpose carbide drill line.

Installation Notes

Carbide drill bits require secure chuck or collet clamping to prevent slippage and bit fracture during operation. Always verify spindle speed and feed rate are appropriate for carbide tooling in the target material before drilling. Carbide is brittle — avoid side loading, interrupted cuts without proper technique, or using this bit in applications requiring hammer or impact action. Inspect the cutting edges for chipping before each use; a damaged carbide bit should be removed from service immediately.
