Century Drill Tool Co Inc 96210 Hex Die 1/2-20 Nf

Product Description

The CENTURY DRILL TOOL CO INC 96210 is a 1/2-20 NF fractional hex die designed for hand cutting external threads on fasteners, bolts, and round stock. Built from heat-treated and tempered steel, the die produces file-hard threads that hold their form through repeated use. Precision-formed cutting edges deliver consistent, accurate threading on each pass. The hex body measures 1 inch across the flats, fitting standard hex die stocks used in plumbing, HVAC, and general mechanical trade work. This die is intended for hand-operated applications, not power threading equipment.

The 96210 is suited for field and shop use where a technician needs to chase, repair, or cut new 1/2-20 National Fine threads on metal rod, pipe nipples, or fastener stock. The compact hex profile makes it easy to seat in a standard die stock wrench. Plumbers, HVAC technicians, and maintenance mechanics commonly reach for this die when restoring damaged threads or fabricating custom-length threaded components on the job.

Installation Notes

A licensed mechanic, plumber, or HVAC technician should seat the die firmly and squarely in a properly sized die stock before beginning threading. Apply cutting oil to the work stock and die to reduce friction and extend die life. Start the die straight to avoid cross-threading, and back off periodically to clear chips. Do not use this die in a power-driven threading tool — it is rated for hand operation only.
