Bosch BTD58S 58 Pc Tap and Die Set Carbon Steel

Product Description

The BOSCH BTD58S is a 58-piece tap and die set built for threading, re-threading, and thread repair across a wide range of inch and metric fastener sizes. The set includes plug-chamfer taps ranging from 6-32 to 1/4-18 and hex dies ranging from 6-32 to 3/4-16. All taps and dies are manufactured from carbon steel. Die hex size is 1 inch. The kit ships in a plastic storage case and includes a screw pitch gauge, spiral screw extractors, two tap wrenches, a T-handle tap wrench, and die stocks, making it a self-contained threading solution for bench or field work. Total set weight is 11.78 pounds.

This set is suited for general-purpose threading tasks encountered in mechanical, HVAC, plumbing, and electrical trade work. It covers the most common unified national coarse and fine thread sizes used in trade applications, from small machine screw threads at 6-32 up to 3/4-16 for larger fastener stock. The plug chamfer on the taps makes them appropriate for through-hole threading. The included die stocks accommodate both 1 inch and 1-7/16 inch hex dies, supporting the full range of dies in the set.

Installation Notes

Tap and die work is performed by machinists, mechanics, and licensed trade professionals including HVAC technicians and plumbers during equipment repair and installation. Always secure the workpiece and use appropriate cutting oil when threading ferrous materials to extend tool life and improve thread quality. Inspect taps for cracks or wear before use and never apply excessive torque, which can cause tap breakage in the workpiece. Follow applicable workplace safety guidelines when operating tap wrenches in confined spaces.
