Value Collection JY79772653 Bspt Pipe Tap 1-1/2-11

Product Description

The VALUE COLLECTION JY79772653 is a straight-flute British Standard Pipe Tap designed to cut 1-1/2-11 BSPT internal threads in a variety of metals and materials. Built from high speed steel (HSS) with a bright, uncoated finish, this tap delivers consistent thread form in applications where BSPT tapered pipe threads are required. The bottoming chamfer allows threading closer to the bottom of a blind hole than a taper or plug chamfer. Seven flutes provide adequate chip clearance during cutting. Right-hand thread direction is standard. This tap is used by machinists, pipefitters, and maintenance technicians working to British pipe thread standards.

This tap is suited for production and maintenance applications requiring BSPT threads in ferrous and non-ferrous materials. It is appropriate for through-hole or near-bottom blind-hole threading where a bottoming chamfer is specified. Common applications include hydraulic fittings, pneumatic manifolds, and fluid-system components manufactured or maintained to British Standard pipe thread specifications. Overall length is 4.5 inches, with a shank diameter of 0.9843 inches and a square drive size of 1.125 inches, making it compatible with standard tap wrenches and holders of appropriate size.

Compatibility

Designed for use in any application requiring 1-1/2-11 BSPT internal threads. Fits standard tap wrenches and machine tap holders with a 1.125-inch square drive.

Installation Notes

This tap should be installed by a qualified machinist or pipefitter familiar with British Standard pipe thread tolerances. Secure the workpiece firmly before starting. Use appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Ensure the tap is properly aligned to avoid thread damage or tap breakage.
