Kennametal 1541654 Hand Tap 10-24 Unc Plug Rh Hss

Product Description

The KENNAMETAL 1541654 is a straight-flute hand tap designed to cut 10-24 UNC internal threads in a variety of workpiece materials. Built from high-speed steel with a bright, uncoated finish, this plug-chamfer tap is suited for through-holes and blind holes where a plug lead is appropriate. It measures 2.38 inches overall length with a thread length of 0.875 inches (7/8 inches) and a shank diameter of 0.194 inches. The H3 thread limit provides controlled oversize tolerance for consistent class 2B and 3B thread fit. Machinists, tool-and-die makers, and maintenance technicians install this tap by hand with a tap wrench or T-handle driver.

This tap is specified for hand-tapping operations in cast iron and non-ferrous metals, making it a practical choice for general machining, maintenance, repair, and fabrication work. It falls within the Kennametal Series 5305 and 5303 tap families. Applications include creating machine screw threads in brackets, housings, panels, and fixtures where the standard 10-24 UNC thread form is required. The right-hand thread direction and plug chamfer allow easy starting in pre-drilled holes sized to standard tap drill specifications.

Installation Notes

This tap is intended for hand-tapping with a tap wrench or T-handle driver; ensure the workpiece is securely fixtured before starting. Always use an appropriate cutting fluid for the workpiece material to reduce friction and extend tool life. Back the tap off periodically to break chips and prevent binding, particularly in deeper holes. Inspect the tap for wear or damage before each use and replace if chipping or thread deformation is observed.
