Cleveland C54272 Tap Set 8-32 Unc 4 Flute Hss

Product Description

The CLEVELAND C54272 is a 3-piece tap set designed for cutting 8-32 UNC internal threads in metal workpieces. The set includes all three chamfer styles — bottoming, plug, and taper — giving machinists and maintenance technicians the flexibility to start, advance, and finish threads in a single set. Each tap is machined from high speed steel (HSS) with a bright finish and features 4 flutes for efficient chip evacuation. Overall length is 2.125 inches with a thread length of 0.38 inches. Thread direction is right hand, and the thread limit is H2, making this set suitable for standard tolerance threading applications.

This tap set is used in machine shops, maintenance and repair operations, and fabrication environments where 8-32 UNC threads are required. The three-piece configuration — taper for starting the thread in a through-hole or open setup, plug for general-purpose threading, and bottoming for threading to the bottom of a blind hole — covers the full range of threading tasks encountered in typical metalworking. It is appropriate for use in steel, aluminum, and other machinable metals consistent with HSS tooling capability.

Key Features

• Three chamfer styles included: bottoming, plug, and taper for complete threading versatility
• High speed steel construction provides durability in ferrous and non-ferrous metals
• 4-flute design promotes efficient chip removal and clean thread formation
• Bright finish with no coating — suitable for use with cutting fluid or oil
• H2 thread limit for standard fit tolerances on 8-32 UNC threads
• Right-hand thread direction, 2.125 inch overall length

Compatibility

Designed for cutting 8-32 UNC right-hand internal threads. Fits standard tap handles and tap wrenches sized for this thread range. Verify tap holder collet or chuck capacity before use.

Installation Notes

Taps should be installed and operated by machinists or qualified maintenance technicians familiar with threading procedures. Always secure the workpiece firmly and use appropriate cutting fluid to extend tool life and improve thread quality. Start with the taper tap to align the thread, progress to the plug tap, and use the bottoming tap last when threading to the bottom of a blind hole. Inspect the tap for wear or damage before each use and replace if chipping or dulling is observed.
