Century Drill Tool 97319 M12x1.25 Metric Plug Tap 2 Pack

Product Description

The CENTURY DRILL TOOL CO INC 97319 is an M12x1.25 metric plug-style tap designed for hand cutting threads in metal and other materials. Sold as a 2-piece package, this tap features precision-cut threads that are accurately formed to produce consistent, exact threading results on every pass. The steel is heat treated and tempered to achieve file-hard thread faces, extending service life under repeated use. Tradespeople, machinists, and maintenance technicians reach for this tap when creating or restoring internal metric threads in fastener holes during fabrication, repair, or field service work.

The 97319 is suited for hand tapping applications where an M12 coarse-pitch thread profile is required. The plug chamfer style makes it appropriate for through-holes and moderately deep blind holes, providing a balance between starting ease and full thread engagement near the bottom of the cut. It is commonly used in HVAC equipment assembly, plumbing fixture installation, electrical panel fabrication, and general mechanical repair where metric fastener threads must be cut or chased by hand.

Key Features

• M12x1.25 thread specification for accurate metric threading
• Plug-style chamfer for use in through-holes and moderately deep blind holes

Compatibility

Designed as a hand-tap replacement for M12x1.25 metric thread applications across general mechanical, HVAC, plumbing, and electrical trade use.

Installation Notes

This tap is designed for hand operation using a standard tap wrench or T-handle — do not use with power drivers unless the tool is rated for tapping and controlled torque is applied. Before tapping, drill the correct pilot hole diameter for M12x1.25 threads and deburr the entry point. Use cutting fluid or thread-cutting oil to reduce heat buildup and extend tap life. Back the tap off a partial turn periodically to break the chip and prevent binding or breakage.
