Century Drill Tool 97313 Metric Plug Tap M8 X 1.25

Product Description

The CENTURY DRILL TOOL CO INC 97313 is an M8 x 1.25 metric plug-style tap designed for hand cutting internal threads in metal and other materials. The tap features precision-cut threads that are accurately formed to produce consistent, exact threading results on every use. Heat treated and tempered to file-hard hardness, the cutting flutes maintain their edge through repeated use, extending service life. This is a standard trade-shop hand tap suited for machinists, pipefitters, HVAC technicians, electricians, and other trades who need to cut or chase metric threads in the field or at the bench. Each package contains 2 taps.

This tap is intended for hand-cutting applications where a tap wrench or T-handle is used to drive the tool manually. The M8 x 1.25 thread specification is one of the most common metric fastener sizes, appearing in equipment enclosures, HVAC components, electrical panels, pipe hangers, and general mechanical assemblies. The plug chamfer style — typically 3 to 5 lead threads — makes it suitable for through-holes and moderately deep blind holes. It is appropriate for use in both shop and field settings where power tapping equipment is not available or practical.

Compatibility

Designed as a standard M8 x 1.25 hand tap suitable for cutting or chasing metric internal threads in metal workpieces across general mechanical, HVAC, electrical, and plumbing trade applications.

Installation Notes

Use a properly sized tap wrench to drive the tap — do not use power tools unless the tap is rated for machine use. Align the tap perpendicular to the workpiece surface before starting the cut to avoid cross-threading. Apply appropriate cutting fluid to reduce friction and heat buildup, particularly in steel or cast iron. Back the tap off periodically to break chips and clear the flutes, especially in blind holes.
