Cleveland C54536 Hand Tap M8x1.00 Taper 4-flute Hss

Product Description

The CLEVELAND C54536 is a straight-flute hand tap designed for cutting M8x1.00 metric fine internal threads in a wide range of metallic workpieces. Ground from high speed steel and left in a bright, uncoated finish, this tap delivers consistent thread quality under hand-tapping conditions and in low-speed machine tapping setups. The taper chamfer distributes cutting load gradually across the leading flutes, making it well-suited for starting threads in both blind holes and through-holes. Overall length is 2.719 inches, with a thread length of 0.69 inches and a D5 thread limit for predictable fit in 6H tolerance applications.

This tap is intended for threading M8x1.00 metric fine holes in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The taper chamfer style makes it a common first-choice tap for beginning a thread in a pre-drilled hole, particularly where a smooth entry and controlled torque are priorities. It is used in maintenance, repair, and production environments by machinists, tool and die makers, and mechanical tradespeople working with metric-dimensioned components.

Key Features

• M8x1.00 metric fine thread form, 6H class of fit with D5 thread limit
• Taper chamfer for gradual cutting load and easy thread starting in blind and through-holes
• High speed steel construction suitable for alloy steel, carbon steel, aluminum, and free-machining stainless steel
• 4-flute straight flute design for chip clearance in general-purpose threading applications
• Bright uncoated finish — no coating buildup to affect thread dimensions
• Right-hand thread direction, Series 1001

Compatibility

Designed as an OEM-style hand tap for M8x1.00 metric fine thread applications across blind hole and through-hole configurations in compatible metallic materials.

Installation Notes

A licensed machinist or qualified tradesperson should ensure the pilot hole is drilled to the correct tap drill diameter for M8x1.00 metric fine threads before use. Secure the workpiece and use a properly aligned tap wrench to avoid tap breakage. Apply appropriate cutting fluid for the workpiece material, particularly when tapping steel. Never force a tap; reverse periodically to break chips and reduce the risk of binding or breakage.
