Cleveland C54841 Tap Set 3/4-10 Unc 4 Flute Hss 3 Pc

Product Description

The CLEVELAND C54841 is a three-piece tap set designed for cutting 3/4-10 UNC internal threads in metal workpieces. The set includes bottoming, plug, and taper chamfer taps, allowing machinists and maintenance technicians to start, progress, and finish a threaded hole in sequence using a single matched set. All three taps are ground from high speed steel (HSS) with a bright finish and feature four flutes for efficient chip evacuation. Each tap measures 4.25 inches overall length with a 1.22-inch thread length, and all three are right-hand cut with an H3 thread limit for standard tolerance fits.

This tap set is suited for general-purpose threading operations in machine shops, maintenance facilities, and fabrication environments. The 3/4-10 UNC thread form is a coarse-pitch designation widely used in structural fastening, equipment repair, and heavy fabrication. The three-tap sequence is standard practice when threading blind holes or when full thread depth at the bottom of a bore is required. HSS construction handles a broad range of materials including mild steel, aluminum, and cast iron at conventional cutting speeds.

Key Features

Compatibility

Designed for cutting 3/4-10 UNC right-hand internal threads in standard threading applications across maintenance, machining, and fabrication trades.

Installation Notes

Tap installation is typically performed by machinists or maintenance mechanics using a tap wrench or tapping attachment in a drill press or mill. Always secure the workpiece firmly and use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Follow the standard three-tap sequence: taper first, then plug, then bottoming for blind holes requiring full thread depth. Inspect the tap for wear or chipping before each use and replace any damaged tap in the set before continuing.
