Titan Usa TC19115 Solid Carbide Jobber Drill Letter O

Product Description

The TITAN USA TC19115 is a solid carbide jobber-length drill bit sized at Letter O (0.3160 inches) with a 118-degree split point. It is designed for general-purpose drilling applications and is built from solid carbide throughout, providing higher hardness and wear resistance than high-speed steel alternatives. The bright, uncoated finish suits applications where coating is unnecessary or where coolant compatibility is a factor. With an overall length of 3.75 inches and a regular spiral flute, this bit produces consistent chip evacuation in a wide range of materials. Machinists, tool-and-die workers, and manufacturing maintenance technicians are the primary users.

The TC19115 is suited for drilling aluminum, non-ferrous metals, and similar materials where solid carbide tooling provides a clear advantage in feed rate and tool life. It fits standard drilling operations on CNC machining centers, drill presses, and rigid setup manual machines. The straight cylindrical shank accommodates standard drill chucks and collet systems accepting a 0.3160-inch shank diameter. The 8xD flute-to-diameter ratio supports drilling depths up to 2.375 inches without retract cycles in most applications.

Key Features

• Solid carbide construction for high wear resistance and rigidity in non-ferrous and aluminum drilling
• 118-degree split point reduces thrust force and improves self-centering at entry
• Bright, uncoated finish suitable for use with or without cutting fluid
• Regular spiral, 2-flute design promotes efficient chip clearance
• Straight cylindrical shank at 0.3160 inches fits standard chucks and collets
• Maximum drilling depth of 2.375 inches within a compact 3.75-inch overall length

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks and collet holders accepting a 0.3160-inch straight shank. Primary workpiece materials include aluminum and non-ferrous metals per the TC19 series specifications.

Installation Notes

This drill bit is intended for installation by machinists or maintenance technicians in a rigid machine spindle setup. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet to the specified engagement depth before tightening. Coolant-through is not supported on this bit, so external cutting fluid or dry cutting practices should be used as appropriate for the workpiece material.
