Cleveland C54933 Hand Tap 1-14 Uns Taper Rh 3B H4

Product Description

The CLEVELAND C54933 is a 1-14 UNS straight flute hand tap designed for cutting internal threads in both blind holes and through-holes. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread quality across a range of materials. It features a taper chamfer, a right-hand thread direction, and a 3B class of fit with an H4 thread limit. The 4-flute straight flute design provides chip clearance and stability during hand tapping operations. Overall length is 5.125 inches, with a thread length of 2.5 inches. Licensed machinists, tool and die makers, and maintenance technicians are the primary users of this tap in both shop and field environments.

This tap is suited for threading operations in alloy steel, aluminum, carbon steel, and free-machining stainless steel. It performs in both blind hole and through-hole applications, making it a versatile choice for general machining, maintenance, and fabrication work. The 1-14 thread size and UNS thread standard position this tap for use in larger-diameter fastener applications common in industrial and heavy equipment contexts. It belongs to Cleveland Series 1001.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench or tapping fixture. Always secure the workpiece and ensure the hole is drilled to the correct tap drill diameter before starting the thread. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread finish. Follow safe tooling practices and power down any associated equipment before performing hand tapping operations in live machinery.
