Cleveland C54626 M10x1.50 Bottoming Hand Tap Hss

Product Description

The CLEVELAND C54626 is a 4-flute straight flute hand tap designed for cutting M10x1.50 metric coarse internal threads in ferrous and non-ferrous workpieces. Built from high speed steel with a bright uncoated finish, it delivers reliable thread formation in production and maintenance environments. The bottoming chamfer allows threading to within a few threads of the bottom of a blind hole, making it the correct choice when full thread depth is required close to the base of the bore. Overall length is 2.938 inches with a thread length of 1.25 inches (31.75 mm). The shank diameter measures 0.381 inches and the square drive is 0.286 inches, fitting standard tap wrenches.

This tap is suited for use in machine shops, toolrooms, and field maintenance applications where metric coarse blind hole or through-hole threading is required. It conforms to a 6H class of fit and D6 thread limit, producing threads appropriate for standard metric fastener engagement in precision assemblies. Typical material applications include alloy steel, carbon steel, aluminum, and free-machining stainless steel. It is a manually driven tap intended for use with a tap wrench or tapping fixture rather than a CNC spindle.

Key Features

• Bottoming chamfer for threading close to the bottom of blind holes
• 4-flute straight flute geometry provides chip control in through-hole and short blind-hole applications
• High speed steel construction supports use across alloy steel, carbon steel, aluminum, and free-machining stainless steel
• 6H class of fit and D6 thread limit for standard metric fastener compatibility
• Bright uncoated finish — no heat treatment coating to spall or chip
• Right-hand thread direction, M10x1.50 metric coarse pitch

Compatibility

Designed as an OEM-style hand tap for M10x1.50 metric coarse threading operations in blind holes and through holes across standard machinable materials.

Installation Notes

Installation is performed by machinists or maintenance technicians using a properly sized tap wrench. Before tapping, verify the pilot hole is drilled to the correct tap drill diameter for M10x1.50 and that the workpiece is securely fixtured. Apply cutting fluid appropriate for the workpiece material to reduce tap wear and improve thread finish. For bottoming taps, start the thread with a taper or plug tap first, then follow with this bottoming tap to complete the thread depth.
