Cleveland C54618 Hand Tap M10x1.25 Plug Rh Hss

Product Description

The CLEVELAND C54618 is a straight-flute hand tap designed for cutting M10x1.25 metric fine internal threads in both blind holes and through-holes. Manufactured from high speed steel with a bright uncoated finish, this plug-chamfer tap provides a moderate lead-in of several threads, making it well suited for starting in pre-drilled holes and running threads near the bottom of blind bores. The tap carries a D5 thread limit and a 6H class of fit, delivering consistent thread tolerance for precision machined components. Overall length is 2.938 inches with a 1.25-inch threaded section. Four flutes provide chip clearance and cutting stability across a range of workpiece materials.

This tap is intended for use in machine shops, maintenance and repair operations, and production environments where metric fine threads are required. It is suited for threading alloy steel, carbon steel, aluminum, and free-machining stainless steel. The plug chamfer style makes it a general-purpose choice for both new thread cutting and chase work where thread access is not severely restricted. It is sold individually and is part of the Cleveland Series 1002 line of hand taps.

Installation Notes

This tap is installed by machinists and maintenance technicians using a tap wrench or tapping fixture aligned to a pre-drilled pilot hole sized for the M10x1.25 thread form. Ensure the workpiece is securely fixtured and apply appropriate cutting fluid for the workpiece material before tapping. For blind holes, clear chips periodically by reversing the tap to prevent packing and tap breakage. Follow applicable shop safety practices when working with sharp cutting tools.
