Titan Usa TC18740 Spotting Drill 5/8in 90deg Solid Carbide

Product Description

The TITAN USA TC18740 is a solid carbide spotting drill designed to accurately locate and start holes before drilling operations. With a 90-degree point angle and a 0.625-inch cutting diameter, this tool creates precise, burr-free spot indentations that guide twist drills and prevent walking on flat or curved workpiece surfaces. The overall length is 3 inches, with a 1.25-inch flute length and a 0.625-inch straight cylindrical shank. Two spiral flutes clear chips efficiently during short-engagement spotting passes. Machining professionals and tool-and-die shops use this drill for general-purpose spotting on a wide range of materials.

This spotting drill fits standard drill chucks and collet holders with a 0.625-inch bore. It is suited for use on CNC machining centers, manual mills, and drill presses in production and job-shop environments. The bright uncoated finish makes it a straightforward general-purpose option for spotting operations where coated tooling is not required. Right-hand cutting direction is standard for conventional spindle rotation. The tool is part of TITAN USA Series 187.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the tool holder is properly secured before inserting or removing the drill. Verify runout with a dial indicator after chucking to maximize tool life and hole location accuracy. Follow the machine manufacturer guidelines for spindle speed and feed rate when spotting with solid carbide tooling.
