Titan Usa TC19126 Solid Carbide Jobber Drill Bit Letter Z

Product Description

The TITAN USA TC19126 is a solid carbide jobber-length drill bit sized to Letter Z (0.4130 inches) with a 118-degree split point and a bright, uncoated finish. It is designed for general-purpose drilling in aluminum, non-ferrous metals, and other materials where carbide rigidity and edge retention outperform high-speed steel. The regular spiral flute geometry promotes efficient chip evacuation, and the straight cylindrical shank seats securely in standard drill chucks. With an overall length of 4.5 inches and a flute length of 2.875 inches, this bit fits the typical jobber-length reach needed across machining, fabrication, and maintenance applications.

The TC19126 is suited for drilling operations in machine shops, production environments, and field maintenance settings where letter-size holes are required. The split point geometry reduces walking at drill entry and lowers the thrust needed to start a hole, making it practical for use in drill presses, CNC machining centers, and hand-held power tools. Its solid carbide construction handles aluminum, brass, copper, and similar non-ferrous materials. The right-hand cutting direction is standard for conventional drilling setups.

Key Features

• Solid carbide construction for enhanced rigidity and wear resistance compared to high-speed steel
• 118-degree split point reduces walking and lowers entry thrust
• Regular spiral flute promotes consistent chip evacuation during drilling
• Bright, uncoated finish suitable for non-ferrous and aluminum workpieces
• Straight cylindrical shank compatible with standard drill chucks and collets
• General-purpose TC19 series rated for a 7xD flute-to-diameter ratio

Compatibility

Designed as an OEM-style general-purpose jobber drill for use in standard drill presses, CNC machining centers, and compatible power tool chucks that accept a 0.4130-inch straight shank.

Installation Notes

Installation and operation should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drill press or machining center spindle is fully stopped and locked out before inserting or removing the bit. Verify chuck or collet runout is within acceptable limits before drilling, as excessive runout accelerates carbide edge wear. Use appropriate cutting fluid or air blast for chip clearing when drilling deeper holes, and do not exceed the maximum drilling depth of 2.875 inches for this bit.
