Century Drill Tool 97307 M4 X 0.75 Metric Plug Tap

Product Description

The CENTURY DRILL TOOL CO INC 97307 is an M4 x 0.75 metric plug-style tap designed for hand cutting internal threads in metal, plastic, and similar materials. The tap features precision-cut threads that are accurately formed to produce consistent, exact thread profiles on every pass. The tool is heat treated and tempered to achieve file-hard thread surfaces, which extends service life and maintains cutting geometry through repeated use. Supplied in a package of two, it is a standard choice for machinists, maintenance technicians, and trade professionals who need reliable hand-tapping capability at the M4 x 0.75 pitch.

This tap is suited for hand-threading applications in residential and light industrial maintenance settings where M4 x 0.75 metric threads are required. Common use cases include tapping mounting holes in sheet metal panels, HVAC equipment housings, electrical enclosures, and plumbing fixture hardware. The plug-style chamfer provides a balance between ease of starting and thread engagement depth, making it practical for through-holes and moderately deep blind holes. It is appropriate for use by HVAC technicians, electricians, plumbers, and general maintenance personnel working with metric-fastener assemblies.

Installation Notes

This tap is intended for hand use with a tap handle or T-handle wrench — do not drive with power tools unless the tool is specifically rated for machine use. Secure the workpiece firmly before tapping and apply cutting oil to reduce friction and heat buildup. Back the tap off periodically to break chips and prevent binding, especially in blind holes. Follow applicable shop safety practices and wear eye protection during all cutting operations.
