Value Collection JY9975772 Extension Tap 10-24 Hss

Product Description

The VALUE COLLECTION JY9975772 is a spiral point extension tap designed for cutting 10-24 unified coarse threads in through-hole applications. Built from high-speed steel with a bright uncoated finish, this tap features a plug chamfer and H3 thread limit, making it suitable for tapping operations that require close dimensional tolerances. With a 2-flute design, it channels chips forward ahead of the cutting edge, reducing clogging in through-hole work. At 4 inches overall length, the extended reach gives machinists and maintenance technicians access to recessed or deep-set hole locations that standard-length taps cannot reach.

This tap is used in machine shop, production, and maintenance environments wherever 10-24 UNC through-hole threads are required at depth. The spiral point design makes it best suited for through-holes rather than blind holes, as chips are pushed ahead rather than back. It is appropriate for use in ferrous and non-ferrous metals depending on cutting fluid selection. The right-hand thread direction and 2B and 3B class of fit coverage make it a versatile choice for general fastener thread standards in both light and standard assembly applications.

Key Features

• Spiral point geometry pushes chips forward, reducing chip packing in through-hole tapping
• H3 thread limit provides controlled tolerance for consistent thread fit across 2B and 3B fit classes
• 4 inches overall length provides extended reach for recessed or deep-set hole locations
• High-speed steel construction offers durability across a range of common work materials
• Bright uncoated finish allows direct visual inspection of the tool edge before and after use
• Plug chamfer with 2 flutes balances cutting speed and chip clearance for production and maintenance use

Compatibility

Designed as an OEM-style replacement or direct-use tap for applications requiring 10-24 UNC right-hand threads in through-hole configurations where extended reach is needed.

Installation Notes

Installation should be performed by a machinist or qualified maintenance technician using a properly sized tap wrench or tapping head. Secure the workpiece firmly before tapping and align the tap perpendicular to the hole axis to avoid thread run-out or tap breakage. Apply cutting fluid appropriate to the work material throughout the operation. Do not use this spiral point tap in blind holes, as forward chip ejection requires an open exit path.
