The CLEVELAND C54597 is a 3/8-24 bottoming hand tap designed for cutting internal threads in blind holes and through-holes. Built from high speed steel with a bright uncoated finish, it runs four straight flutes and carries a 3B class of fit with an H3 thread limit. The bottoming chamfer allows threading close to the bottom of a blind hole, making it a practical choice where thread depth is critical. Overall length is 2.938 inches with a thread length of 0.75 inches. This tap is installed by machinists, toolroom technicians, and maintenance trades working in production or repair environments.
The C54597 is suited for tapping 3/8-24 UNF threads in a range of materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. The straight flute geometry works well in both blind hole and through-hole applications. Series 1003 taps like this one are commonly found in machine shops, MRO toolrooms, and field maintenance kits where a reliable, general-purpose hand tap is required for right-hand thread cutting in standard fine-thread applications.
Designed for cutting 3/8-24 UNF right-hand internal threads in alloy steel, carbon steel, aluminum, and free-machining stainless steel in both blind hole and through-hole applications.
This tap is intended for use by qualified machinists or maintenance technicians operating a tap wrench or manual tapping fixture. Secure the workpiece firmly before tapping and apply an appropriate cutting fluid for the material being threaded. Back the tap out periodically to break chips and prevent binding, particularly in blind holes. Inspect the tap for wear or chipping before each use to avoid thread damage or tap breakage.
