Regal Cutting Tools 013595AS Hand Tap 1-5/16-12 Unf Plug Rh Hss

Product Description

The REGAL CUTTING TOOLS 013595AS is a straight-flute hand tap designed for cutting right-hand 1-5/16-12 UNF internal threads in ferrous and non-ferrous materials. Built from high speed steel with a bright, uncoated finish, this tap is suited for through-hole and blind-hole applications where a plug chamfer is appropriate. The H5 thread limit provides a controlled tolerance for close-fitting threaded assemblies. With 6 flutes and a plug chamfer, the tool advances smoothly into a pre-drilled hole and is well-matched to machine or hand-tapping operations where chip clearance is manageable and thread accuracy is required.

This tap is used in production and maintenance settings where large-diameter UNF threads are required. The 1-5/16-12 thread specification is common in mechanical assemblies, hydraulic fittings, and structural fastener applications where a fine thread pitch offers improved holding strength over coarse alternatives. Machinists, tool-and-die professionals, and maintenance technicians are the typical users. It is suited for use in standard tapping fixtures or with a hand tap wrench in manual operations.

Key Features

• 1-5/16-12 UNF right-hand thread for fine-pitch large-diameter internal threading
• Plug chamfer (3-5 thread lead) for easy starting in through-holes or deep blind holes
• H5 thread limit for close-tolerance thread fit in precision assemblies
• 6-flute straight-flute geometry suited for shorter chip materials and controlled cutting
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish for general-purpose use without coating-related dimensional offset

Compatibility

Designed as a standard replacement hand tap for applications requiring 1-5/16-12 UNF right-hand internal threads. Compatible with standard tap wrenches and tapping heads accepting the appropriate shank diameter.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench or machine tapping setup. Always drill the correct tap drill size for a 1-5/16-12 UNF thread before tapping, and ensure the workpiece is securely fixtured. Use appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Never reverse-drive a tap while chips are packed in the flutes, as this increases breakage risk.
