Cleveland C54767 Hand Tap 9/16-18 Unf Bottoming Hss

Product Description

The CLEVELAND C54767 is a 9/16-18 UNF straight-flute hand tap designed for cutting internal threads in blind holes and through-holes. Manufactured from high speed steel with a bright uncoated finish, it delivers a Class 2B thread fit with an H3 thread limit for consistent dimensional accuracy. The tap features a bottoming chamfer, allowing threads to be cut to the full depth of a blind hole. With four flutes and right-hand thread direction, it is suited for general-purpose tapping operations in machine shops, maintenance environments, and fabrication settings. Licensed machinists and toolroom technicians are the primary users.

This tap is intended for threading operations in a range of ferrous and non-ferrous materials. Its material application list includes alloy steel, aluminum, carbon steel, and free-machining stainless steel. The bottoming chamfer makes it especially useful as the finishing tap in a tap set sequence when the full thread depth must reach close to the bottom of a blind hole. It belongs to Cleveland Series 1003 and is packaged as a single unit.

Key Features

• Bottoming chamfer for threading to the bottom of blind holes
• High speed steel construction for durability in production and maintenance tapping
• Bright uncoated finish compatible with a wide range of cutting fluids
• H3 thread limit maintains Class 2B fit tolerances
• Four straight flutes for chip clearance in through-hole and blind-hole applications
• Coolant-through design not required — suitable for standard hand or machine tapping setups

Compatibility

Designed for use in 9/16-18 UNF blind-hole and through-hole threading applications in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench or tapping attachment. Always secure the workpiece and ensure the tap is started perpendicular to the surface to avoid thread misalignment or tap breakage. When tapping blind holes with a bottoming tap, use a plug or taper tap first to establish the thread before finishing with this bottoming tap. Apply appropriate cutting fluid for the workpiece material throughout the operation.
