Cleveland C54690 Hand Tap M12x1.75 Plug Hss Bright 6H

Product Description

The CLEVELAND C54690 is a 4-flute straight-flute hand tap designed for cutting M12x1.75 metric coarse internal threads in both blind and through-hole applications. Manufactured from high speed steel with a bright uncoated finish, this plug-chamfer tap provides a balanced entry angle suited for general-purpose threading work across a range of ferrous and non-ferrous materials. The tap measures 3.375 inches overall length with a 1.66-inch thread length, and carries a 6H class of fit with a D6 thread limit for consistent, tolerance-correct threads. It is a standard tool for machinists, maintenance technicians, and toolroom operators working with metric fastener specifications.

This tap is suited for production and maintenance threading operations where M12x1.75 metric coarse threads are required. The plug chamfer makes it appropriate for both starting threads in through-holes and threading blind holes where adequate thread depth clearance exists. Compatible material applications include alloy steel, aluminum, carbon steel, and free-machining stainless steel. It is part of the Cleveland Series 1002 hand tap line and is intended for hand tapping as well as low-speed machine tapping setups.

Compatibility

Designed for threading M12x1.75 metric coarse internal threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces in blind-hole and through-hole applications.

Installation Notes

This tap should be installed using an appropriate tap wrench or tapping fixture; ensure the workpiece is securely fixtured before starting. Power down or de-energize any machine tool before mounting or removing the tap from a holder. Apply cutting fluid appropriate for the workpiece material to reduce heat and extend tool life. Follow standard machinist practice for tap alignment to avoid tap breakage in the hole.
