Cleveland C54909 Hand Tap M24x3.00 Bottoming Hss

Product Description

The CLEVELAND C54909 is a bottoming chamfer hand tap designed for cutting metric coarse internal threads in both blind and through-hole applications. Built from high speed steel (HSS) with a bright, uncoated finish, this 4-flute straight flute tap produces M24x3.00 threads to a 6H class of fit at a D8 thread limit. The overall length is 4.906 inches with a thread length of 2.22 inches. The bottoming chamfer allows threading close to the bottom of a blind hole, making it the final step in a standard tap sequence. Licensed machinists, tool-and-die makers, and maintenance technicians use this tap for production and repair work on metric-threaded fastener holes.

This tap is suited for threading M24x3.00 metric coarse holes in a range of materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. It is appropriate for both blind hole and through-hole threading operations. The Series 1003 designation places it within Cleveland's standard production hand tap line, making it a common choice for job shop, manufacturing floor, and MRO maintenance threading tasks where metric coarse threads are required.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• High speed steel construction for durability across ferrous and non-ferrous materials
• 4-flute straight flute geometry provides chip clearance and thread-form stability
• 6H class of fit with D8 thread limit meets standard metric tolerance requirements
• Bright uncoated finish suitable for use with standard cutting fluids
• Right-hand thread direction, metric coarse pitch of 3.00 mm

Compatibility

Designed as an OEM-style replacement or direct-use hand tap for M24x3.00 metric coarse threading operations. Compatible with standard tap wrenches sized for a 0.57 inch square drive.

Installation Notes

This tap is installed using a hand tap wrench or machine holder rated for the shank diameter. Always apply an appropriate cutting fluid for the workpiece material before threading to reduce heat and extend tap life. Ensure the hole is drilled to the correct tap drill diameter for M24x3.00 metric coarse threads before use. When tapping blind holes, use this bottoming tap as the final pass after a taper or plug tap has established the thread form.
