Value Collection JY4863320 Hand Tap 1-3/16-32 Uns Hss

Product Description

The VALUE COLLECTION JY4863320 is a straight-flute hand tap designed for cutting internal threads in through-holes and blind holes where hand-tapping operations are required. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap cuts a 1-3/16-32 UNS right-hand thread to a Class 3B fit tolerance. The H4 thread limit designation indicates a controlled oversize grind suited for threading harder materials or plated hole applications. At 4 inches overall length, the tap provides adequate reach for standard production and maintenance threading tasks. Licensed machinists, toolroom technicians, and maintenance mechanics are the primary users of this tool.

This tap is intended for use in metalworking, toolroom, and maintenance applications requiring a 1-3/16-32 UNS thread form. The plug chamfer — typically 3 to 5 threads — makes it well suited for starting threads in through-holes or for following a taper tap in a two-tap sequence on blind holes. The 6-flute design distributes cutting load across more cutting edges compared to standard 4-flute taps, which helps extend tool life and improves thread finish when working in softer ferrous and non-ferrous metals.

Key Features

• 1-3/16-32 UNS thread form, right-hand cut
• High speed steel construction for durability across a range of workpiece materials
• Bright uncoated finish suitable for use with standard cutting fluids
• Plug chamfer for versatile use in through-holes and as a second-tap in blind-hole sequences
• 6-flute straight-flute design for improved load distribution and thread finish
• Class 3B fit, H4 thread limit for precise tolerance control

Compatibility

Designed as an OEM-style hand tap for use in standard tap wrenches and T-handle tap holders sized for large-diameter machine taps requiring a 1-3/16-32 UNS thread form.

Installation Notes

This tap is installed by hand using a tap wrench or T-handle holder; it is not intended for machine tapping unless the operator confirms the drive configuration is appropriate. Secure the workpiece firmly and ensure the tap is started perpendicular to the hole surface to avoid thread damage or tap breakage. Apply a suitable cutting fluid throughout the operation and reverse the tap periodically to break chips. Follow applicable shop safety procedures when working with cutting tools.
