Cleveland C55132 Hand Tap 1/2-13 Unc Plug Tin Hss

Product Description

The CLEVELAND C55132 is a straight-flute hand tap designed for cutting 1/2-13 UNC internal threads in a range of ferrous and non-ferrous workpiece materials. Built from high speed steel with a titanium nitride (TiN) coating, it offers improved wear resistance and reduced friction compared to uncoated taps. The plug chamfer — with several lead threads tapered — makes it well suited for both through-hole and blind-hole threading applications. Four flutes provide adequate chip clearance while maintaining tool rigidity. The tap carries a Class 3B thread fit at an H3 thread limit, meeting close-tolerance threading requirements common in production and maintenance machining environments. Installation is by hand or through a tapping fixture.

This tap is used in job shops, maintenance and repair operations, and production machining environments where 1/2-13 UNC threads must be cut or chased. It is appropriate for blind-hole and through-hole applications in alloy steel, carbon steel, aluminum, and free-machining stainless steel. The plug chamfer style makes it the standard choice when starting a tap in a pre-drilled hole where the tap cannot be run completely through from one side. It belongs to the Cleveland Series 1002TN product line.

Key Features

• 1/2-13 UNC thread form, right-hand, Class 3B fit at H3 thread limit
• TiN coating increases surface hardness and extends tool life in abrasive materials
• Plug chamfer provides 3-5 lead threads for controlled thread start in blind or through holes
• 4-flute straight-flute geometry supports chip clearance in a wide range of materials
• High speed steel construction provides toughness for hand tapping and low-speed machine tapping
• No coolant-through design — suitable for hand tapping and standard tapping setups

Compatibility

Designed for cutting 1/2-13 UNC internal threads in alloy steel, carbon steel, aluminum, and free-machining stainless steel; compatible with both blind-hole and through-hole threading applications per Series 1002TN design specifications.

Installation Notes

This tap is installed by machinists and maintenance technicians using a standard tap wrench, T-handle, or tapping fixture. Always use the correct tap drill size for a 1/2-13 UNC thread before tapping. Ensure the workpiece is securely fixtured and apply appropriate cutting fluid for the material being threaded. Back the tap off periodically to break chips and prevent binding, particularly in blind holes.
