Cleveland C54354 Hand Tap 10-32 Unf Plug 3-flute Hss

Product Description

The CLEVELAND C54354 is a straight-flute hand tap designed for cutting 10-32 UNF internal threads in a wide range of metallic workpieces. Ground from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent thread form in both blind and through-hole applications. The plug chamfer (4-5 thread lead) provides a gradual cutting action that reduces starting torque and helps align the tap squarely in the hole. Overall length is 2.375 inches, with a 0.500-inch thread length, a 0.194-inch shank diameter, and a 0.250-inch square length for positive drive engagement in a standard tap wrench or holder.

This tap is suited for job-shop, maintenance, and production threading operations where 10-32 UNF threads are required. The straight-flute geometry is appropriate for through-hole threading and short blind holes where chips can be pushed ahead of or cleared below the tap. Machinists and tool-and-die technicians commonly use Series 1002 taps for hand-tapping and low-speed machine tapping in ferrous and non-ferrous materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel.

Key Features

• 10-32 UNF thread form, right-hand, Class 2B fit for standard tolerance applications
• H3 thread limit for consistent sizing across production runs
• Plug chamfer with 3 straight flutes for controlled chip flow in through and short blind holes
• High-speed steel construction for durability across alloy steel, carbon steel, aluminum, and free-machining stainless steel
• Bright uncoated finish — no coating buildup to affect thread tolerance
• 0.152-inch square drive size fits standard tap wrenches and holders

Compatibility

Designed for cutting 10-32 UNF internal threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces in both blind-hole and through-hole threading applications.

Installation Notes

Hand taps should be installed in a properly sized tap wrench or T-handle for controlled torque application. Always use a cutting fluid appropriate for the workpiece material to extend tool life and improve thread quality. Ensure the tap is started perpendicular to the workpiece surface to avoid tap breakage and thread distortion. Back the tap off periodically during hand tapping to break and clear chips, particularly in blind holes.
