Century Drill Tool 97320 Metric Plug Tap 12.0x1.50 2-pack

Product Description

The CENTURY DRILL TOOL CO INC 97320 is a metric plug-style tap sized 12.0x1.50, designed for hand cutting internal threads in metal workpieces. Precision-formed threads deliver consistent, exact thread engagement with each use. The tap is heat treated and tempered to achieve file-hard threads, which extends service life and maintains cutting accuracy over repeated use. This tool is well suited for machinists, maintenance technicians, pipefitters, and field service professionals who need reliable hand-tapping capability in metric thread sizes. Each package contains 2 taps.

This tap is intended for hand cutting applications where a plug chamfer is appropriate — typically for threading through-holes or continuing a thread started by a taper tap. It is commonly used in metal fabrication, mechanical maintenance, and repair work across HVAC, plumbing, and industrial equipment service. The 12.0x1.50 thread specification is a standard coarse metric thread pitch used widely in machinery and equipment fastener applications.

Key Features

• Plug-style chamfer for general-purpose through-hole and intermediate threading
• Precision-formed threads for consistent, accurate thread cutting
• Heat treated and tempered construction for file-hard cutting edges
• Extended tool life compared to non-heat-treated taps
• Designed for hand cutting applications
• Sold as a 2-pack for backup availability on the job

Compatibility

Designed as a standard metric plug tap for hand-tapping applications requiring a 12.0x1.50 thread specification. Compatible with standard tap handles and T-handle wrenches sized for this tap.

Installation Notes

Installation requires a correctly sized tap handle or T-handle wrench rated for hand-tapping operations. The workpiece should be securely clamped before tapping begins. Apply cutting oil or thread-cutting lubricant to reduce heat and extend tap life, particularly in ferrous metals. Back off the tap periodically to break chips and prevent binding or breakage.
