Cleveland C54489 Hand Tap M7x1.00 Taper Rh D5 Hss

Product Description

The CLEVELAND C54489 is a 4-flute straight flute hand tap designed for cutting M7x1.00 metric coarse internal threads in a range of ferrous and non-ferrous materials. Manufactured from high speed steel with a bright uncoated finish, it is built for hand tapping operations in both blind hole and through-hole applications. The taper chamfer provides a gradual thread lead-in, reducing the force required to start the cut. Overall length is 2-23/32 inches, with a 0.69-inch thread length and a D5 thread limit for close tolerance work to a 6H class of fit. Machinists, tool-and-die makers, and maintenance technicians use this tap for precision threading in production and repair environments.

The C54489 is suited for blind hole and through-hole threading in materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. The taper chamfer style distributes cutting load gradually, making it appropriate for hand-driven tapping with a tap wrench or fixture. It is a Series 1001 tap following metric coarse thread standards, with a right-hand thread direction. The 0.318-inch shank diameter and 3/8-inch square drive are sized for standard tap wrenches used in general machining and maintenance work.

Key Features

• M7x1.00 metric coarse thread form with right-hand cutting direction
• Taper chamfer for gradual thread engagement in blind and through-hole applications
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish — no coating buildup that could affect thread tolerance
• D5 thread limit to 6H class of fit for close-tolerance metric threading
• 4-flute straight flute geometry provides chip clearance and cutting stability

Compatibility

Designed for hand tapping M7x1.00 metric coarse threads in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces. Fits standard tap wrenches accepting a 0.318-inch shank with a 3/8-inch square drive.

Installation Notes

Hand taps should be installed and driven by a qualified machinist or maintenance technician using an appropriately sized tap wrench. Always secure the workpiece before starting the cut, and back off the tap periodically to break chips, particularly in blind holes. Apply cutting fluid suited to the workpiece material to extend tap life and improve thread finish. Never force a tap that has stopped advancing — back out and clear chips before continuing.
