Value Collection JY4880092 Hand Tap 2-1/4-12 Uns Bottoming

Product Description

The VALUE COLLECTION JY4880092 is a bottoming hand tap designed for cutting right-hand internal threads in through-holes and blind holes that require threading close to the bottom. Machined from high speed steel with a bright, uncoated finish, this tap handles standard UNS thread form at 2-1/4-12. It features six straight flutes for effective chip evacuation in short-chipping materials. With an overall length of 5.25 inches and a thread length of 2 inches, it is sized for heavy-duty manual tapping operations. Machinists, tool-and-die technicians, and maintenance mechanics use this tap when a starting or plug tap has already established the thread and a full-depth bottom thread is required.

This tap is suited for production and maintenance environments where 2-1/4-12 UNS bottoming threads are needed in ferrous and non-ferrous workpieces. The H6 thread limit provides a controlled oversize fit appropriate for standard tolerance threading applications. Straight-flute geometry makes it a reliable choice for hand tapping in materials that produce short, brittle chips. It is intended for use with a tap wrench or suitable hand-tapping fixture.

Key Features

• Bottoming chamfer allows threading to within 1-2 threads of the bottom of a blind hole
• High speed steel construction provides wear resistance for hand tapping in a wide range of metals
• Six straight flutes promote chip clearance in short-chipping materials
• H6 thread limit delivers controlled oversize tolerance for standard fit requirements
• Bright, uncoated finish suitable for use with cutting oil or tapping fluid
• Right-hand thread direction conforms to standard fastener orientation

Compatibility

Designed as an OEM-style replacement or direct-use hand tap for applications requiring a 2-1/4-12 UNS right-hand bottoming thread in manual or assisted tapping setups.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Ensure the workpiece is securely fixtured before beginning the tapping operation, and always apply an appropriate cutting fluid or tapping compound to extend tool life and improve thread quality. Back the tap off periodically to break chips and prevent binding. Follow applicable shop safety practices and relevant machinery safety standards when operating tapping equipment.
