Century Drill Tool 97520 M12x1.50 Tap Z Drill Bit Combo 2pc

Product Description

The CENTURY DRILL TOOL CO INC 97520 is a two-piece combo set that pairs an M12 x 1.50 metric plug-style tap with a letter Z drill bit, giving tradespeople a matched set for accurate hand-tapping operations. The tap features precision-cut threads that are accurately formed for consistent, repeatable thread profiles. Both pieces are heat treated and tempered to file-hard hardness, extending service life under regular shop use. This set is designed specifically for hand cutting applications where controlled torque and steady feed rate are critical to producing clean, usable threads in metal workpieces.

This combo set is suited for use in maintenance, repair, and fabrication environments where M12 x 1.50 metric threads are commonly encountered. Typical applications include threading new holes or re-chasing damaged threads in automotive, mechanical, and general industrial work. The inclusion of the correctly sized letter Z drill bit eliminates the need to source a separate tap drill, making this set a practical grab-and-go solution for field technicians and shop mechanics who regularly work with metric fastener patterns.

Key Features

• M12 x 1.50 plug-style tap for standard metric threading by hand
• Includes matching letter Z drill bit sized for correct tap drill clearance
• Precision-cut, accurately formed threads for consistent thread profiles
• Heat treated and tempered to file-hard finish for extended service life
• Designed for hand cutting applications requiring controlled feed and torque
• Two-piece combo pack keeps matched tap and drill together

Compatibility

Designed as an OEM-style replacement or standard two-piece tap-and-drill combo suitable for any hand-tapping application requiring M12 x 1.50 metric thread specification.

Installation Notes

This set is intended for use by machinists, mechanics, and maintenance technicians performing hand-tapping operations. Before tapping, secure the workpiece firmly and drill the pilot hole using the included letter Z bit at an appropriate speed for the material. Apply cutting oil to the tap throughout the threading process and back off the tap periodically to clear chips and reduce the risk of tap breakage. Never force the tap; consistent, controlled hand torque produces the cleanest threads and reduces tool wear.
