Cleveland C57099 Spiral Point Tap 10-24 Unc 2 Flute Hss

Product Description

The CLEVELAND C57099 is a spiral point tap designed for through-hole threading in a wide range of metalworking applications. Built from high speed steel with a bright finish, this plug-chamfer tap features 2 flutes and a right-hand thread direction with a 10-24 UNC thread form. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for production tapping in through-hole operations. With an overall length of 2.375 inches and a thread length of 0.5 inches, this tap is sized for use in standard machine tapping setups. Licensed machinists, tool and die technicians, and maintenance mechanics are the primary installers.

This tap is intended for through-hole threading in alloy steel, aluminum, and carbon steel workpieces. It carries an H7 thread limit designation, indicating a ground oversize tolerance class commonly specified when tapping materials that close on the tap or when thread fit requirements call for a tighter tolerance range. The 1011 series tap fits standard machine tap holders and tapping heads used in drill presses, CNC machining centers, and hand tapping equipment found in job shops and maintenance facilities.

Installation Notes

This tap is intended for use by qualified machinists or maintenance technicians in a machine tapping or hand tapping setup. Always secure the workpiece and ensure the tap is aligned perpendicular to the hole before beginning the threading operation. Use an appropriate cutting fluid for the material being tapped to extend tool life and maintain thread quality. Replace the tap at the first sign of chipping, dulling, or thread form degradation to avoid damage to the workpiece.
