Cleveland C54926 Tap Set 1-8 Unc 4 Flute Hss 3 Pc

Product Description

The CLEVELAND C54926 is a three-piece hand tap set designed for cutting 1-8 UNC threads in metal workpieces. The set includes bottoming, plug, and taper chamfer taps, allowing a machinist or maintenance technician to start, advance, and finish a thread in sequence using a single matched set. Each tap is ground from high speed steel (HSS) with a bright finish and features four flutes for effective chip evacuation. Overall length is 5.125 inches, with a thread length of 2.5 inches. Thread direction is right hand, and the thread limit is H4, making this set appropriate for standard tolerance threading work in general machining and industrial maintenance environments.

This tap set is suited for residential and commercial maintenance shops, manufacturing facilities, and industrial service applications where 1-8 UNC threads are regularly produced or repaired. The three-chamfer progression — taper for starting, plug for general-purpose threading, and bottoming for threading close to a blind hole floor — covers the full range of threading tasks encountered in structural, mechanical, and equipment repair work. Machinists, millwrights, and maintenance technicians are the primary users of this type of set.

Installation Notes

This tap set is intended for use by machinists and trained maintenance personnel familiar with hand tapping and machine tapping procedures. Always use the appropriate cutting fluid for the workpiece material and ensure the tap is properly aligned with the pilot hole before beginning. Secure the workpiece firmly and use a calibrated tap wrench or tapping head sized for the tap shank. Follow shop safety protocols and applicable OSHA standards when operating tapping equipment.
