Titan Usa TC18708 Spotting Drill 0.125in 90deg Solid Carbide

Product Description

The TITAN USA TC18708 is a solid carbide spotting drill designed to create precise starter divots for twist drills, reamers, and other rotary cutting tools. With a 90-degree point angle and a 0.125-inch cutting diameter, it establishes accurate hole locations and reduces drill walk on flat or angled workpiece surfaces. The bright, uncoated solid carbide construction provides rigidity and sharp edge retention on a wide range of materials. At 2 inches overall length, this is a compact tool suited for CNC machining centers, manual mills, and drill presses where controlled spotting depth is required. Installation and use are handled by machinists and toolroom professionals.

The TC18708 is intended for general-purpose spotting operations in metalworking, fabrication, and machine shop environments. The 0.25-inch flute length and 0.125-inch straight cylindrical shank make it compatible with standard collet chucks and drill chucks found on benchtop and production equipment. The two-spiral-flute design promotes chip clearance during shallow spotting passes. It is a single-ended tool from TITAN USA Series 187, sold individually.

Installation Notes

Spotting drills are installed by machinists using standard collet or drill chuck toolholding systems on milling machines, machining centers, or drill presses. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify collet size matches the 0.125-inch shank diameter before clamping. Do not use this tool as a center drill or apply side-loading forces not appropriate for spotting operations.
