Cleveland C54165 Hand Tap M3x0.50 Plug Rh Hss

Product Description

The CLEVELAND C54165 is a straight-flute hand tap designed for cutting internal M3x0.50 metric coarse threads in both blind and through-hole applications. Made from bright, uncoated high speed steel, this plug-chamfer tap is built for use with standard tap wrenches and is suited to manual tapping operations on the shop floor or in the field. The 3-flute geometry provides reliable chip clearance in a range of workpiece materials. Key dimensional specs include a 1.938-inch overall length and a 0.31-inch thread length, with a 6H class of fit and D3 thread limit to hold consistent tolerance across production runs.

This tap is well suited for machining, fabrication, and maintenance operations requiring metric coarse threads in M3 fastener applications. Blind hole and through-hole threading are both supported. The plug chamfer provides a gradual lead-in that is practical for starting threads in pre-drilled holes. It is a common choice for manual tapping in job shops, assembly operations, and field repair work where metric fastener sizes are standard.

Key Features

• Plug chamfer for controlled thread lead-in in blind or through holes
• 3-flute straight-flute design supports chip evacuation during hand tapping
• High speed steel construction handles a broad range of workpiece materials
• Bright, uncoated finish for direct use without added surface treatment
• 6H class of fit with D3 thread limit for consistent metric tolerance control
• Compatible with both blind hole and through-hole threading applications

Compatibility

Designed for cutting M3x0.50 metric coarse internal threads. Suitable for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces as noted by the manufacturer.

Installation Notes

Installation is performed by a machinist or maintenance technician using a standard tap wrench sized to the 0.11-inch square drive. Power down any machinery before tapping threads in situ. Ensure the pilot hole is drilled to the correct M3x0.50 tap drill diameter before starting. Apply cutting fluid appropriate to the workpiece material to reduce heat buildup and extend tap life.
