Century Drill Tool 97306 M4 X 0.70 Metric Plug Tap 2-pack

Product Description

The CENTURY DRILL TOOL CO INC 97306 is an M4 x 0.70 metric plug-style tap designed for hand cutting threaded holes in metal and other machinable materials. Supplied in a 2-piece package, each tap features precision-cut threads that are accurately formed to produce consistent, exact threading results. The tool is heat treated and tempered to achieve file-hard thread geometry, extending service life under repeated use. Plumbers, electricians, HVAC technicians, and general trade professionals reach for plug taps when chasing or cutting metric threads in field repair and fabrication applications.

This tap is intended for hand threading operations where a standard M4 x 0.70 metric thread profile is required. The plug style — with its moderate lead taper — suits through-hole and deeper blind-hole applications where thread engagement needs to begin with a short chamfer before reaching full thread depth. It is well suited to light metalworking tasks common in trade service work, equipment repair, and maintenance environments where metric fastener threads need to be cut or restored on-site.

Key Features

• M4 x 0.70 metric thread form — standard pitch for M4 fastener applications
• Plug-style lead taper for versatile use in through-holes and deeper blind holes
• Precision-cut, accurately formed threads for consistent thread quality
• Heat treated and tempered construction for file-hard threads and extended tool life
• Designed for hand cutting applications — compatible with standard tap handles and T-wrenches
• Supplied as a 2-piece package for backup availability on the job

Compatibility

Designed as an OEM-style hand tap for use with standard tap handles and tap wrenches sized for M4 metric plug taps in hand threading applications.

Installation Notes

Tap installation should be performed by a qualified tradesperson familiar with thread-cutting procedures. Secure the workpiece before beginning and use an appropriate cutting fluid or tapping oil to reduce friction and extend tap life. Apply steady, even pressure and back the tap off periodically to break chips and prevent binding. Never force a tap — if resistance increases significantly, back out and clear chips before continuing.
