Cleveland C55307 Spiral Point Tap 10-24 Unc Tin Hss

Product Description

The CLEVELAND C55307 is a spiral point plug tap designed for through-hole threading in ferrous materials. Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. Configured in a 10-24 UNC thread form with a 2B class of fit, this two-flute tap is suited for production threading in cast iron and steel. The spiral point geometry pushes chips forward ahead of the cutting action, keeping the flutes clear and allowing efficient through-hole operation. The H2 thread limit ensures consistent tolerance control in standard threaded assemblies. Licensed machinists and maintenance technicians alike rely on this tap for reliable, repeatable threads in light to medium-duty applications.

This tap is intended for through-hole threading operations in cast iron and steel workpieces. The plug chamfer style makes it appropriate for use in both hand tapping and machine tapping setups where the tap can pass fully through the material. It performs well in general-purpose machining, MRO, and fabrication environments. At 2.375 inches overall length with a 0.5 inch thread length, it fits standard tap handles and CNC tool holders designed for this shank size.

Compatibility

Designed for through-hole threading in cast iron and steel. Compatible with standard tap handles and machine tapping chucks sized for a 0.194 inch shank diameter. Fits Series 1011TN tooling configurations.

Installation Notes

Through-hole tapping should be performed by a qualified machinist or maintenance technician familiar with cutting tool operation. Ensure the workpiece is securely fixtured and the spindle or tap handle is properly aligned before starting the cut. Apply appropriate cutting fluid for the material being tapped to improve finish quality and tool life. Inspect the tap for chipping or wear before each use and replace if cutting edges are damaged.
