Cleveland C54676 Hand Tap M12x1.25 Plug Rh Hss

Product Description

The CLEVELAND C54676 is an M12x1.25 plug chamfer hand tap designed for cutting metric fine threads in both blind holes and through-holes. Built from high speed steel (HSS) with a bright uncoated finish, this 4-flute straight flute tap produces 6H class-of-fit threads to D5 thread limit tolerance. It measures 3.375 inches overall length with a 1.66-inch thread length and a 0.367-inch shank diameter. Machinists and tool-and-die tradespeople use this tap for hand tapping operations where precise metric fine thread engagement is required in production or maintenance environments.

The C54676 is suited for threading M12x1.25 metric fine applications in both blind hole and through-hole configurations. Its straight flute geometry and plug chamfer make it a practical choice for general-purpose tapping across a range of common workpiece materials. The 4-flute design provides balanced cutting action and adequate chip clearance for moderate-depth threading tasks.

Compatibility

Designed for tapping M12x1.25 metric fine threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces in blind hole and through-hole threading applications.

Installation Notes

This tap is installed and driven by a licensed machinist or qualified tool operator using a standard tap wrench or tapping fixture. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for M12x1.25 before beginning. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Never force a tap if resistance increases unexpectedly; back off to clear chips and prevent breakage.
