Cleveland C54652 Hand Tap 7/16-14 Unc Taper 4-flute Hss

Product Description

The CLEVELAND C54652 is a 7/16-14 UNC straight-flute hand tap designed for cutting internal threads in both blind holes and through holes. Built from high speed steel with a bright uncoated finish, it carries a taper chamfer that guides thread engagement progressively from the start. The 4-flute geometry provides consistent chip formation and stable cutting action. Overall length is 3.156 inches with a thread length of 0.880 inches. Thread limit is H3, and fit class is 2B, making it suitable for standard tolerance internal thread applications. This tap is installed by machinists, tool-and-die workers, and maintenance technicians working in production or repair environments.

The C54652 is suited for threading operations in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The taper chamfer distributes cutting load across the lead threads, which reduces the force needed to start the tap and helps maintain thread quality in both CNC tapping setups and manual hand-tapping operations. It is appropriate for general-purpose threading tasks in manufacturing, MRO, and field repair contexts where a 7/16-14 UNC internal thread is required.

Key Features

• 7/16-14 UNC thread form with right-hand thread direction
• Taper chamfer for progressive thread engagement in blind or through holes
• 4-flute straight-flute design for stable cutting and chip control
• High speed steel construction for durability across a range of workpiece materials
• H3 thread limit, Class 2B fit for standard tolerance internal threads
• Bright uncoated finish — no coating buildup, easy to inspect for wear

Compatibility

Designed for use in blind-hole and through-hole threading applications in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces requiring a 7/16-14 UNC internal thread.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC tapping attachment. Secure the workpiece firmly before beginning the threading operation. Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Do not force a tap that has seized — back off to clear chips and reapply cutting fluid before continuing.
