Value Collection JY79772737 3/8-19 Bspt Pipe Tap Bottoming 4 Flutes

Product Description

The VALUE COLLECTION JY79772737 is a straight-flute British Standard Pipe Tap designed to cut internal BSPT (British Standard Pipe Taper) threads in metal workpieces. Built from high speed steel (HSS) with a bright, uncoated finish, this tap handles 3/8-19 BSPT thread profiles with a bottoming chamfer, allowing threads to be cut close to the bottom of a blind hole. The 4-flute geometry provides balanced cutting action and adequate chip clearance for most ferrous and non-ferrous metals. Machinists, pipefitters, and maintenance technicians use this tool in manual or machine tapping applications wherever BSPT-standard threaded pipe connections are required.

This tap is suited for fabrication shops, maintenance facilities, and field service work involving British Standard Pipe Taper threaded fittings. The bottoming chamfer makes it particularly useful when a plug or taper tap has already started the thread and full thread depth to the bottom of a blind hole is needed. It is appropriate for use in carbon steel, alloy steel, and aluminum workpieces when correct cutting speeds and lubrication are applied. The 3/8-19 BSPT designation is a common thread size found in hydraulic, pneumatic, and fluid-transfer piping systems that follow British standards.

Key Features

• 3/8-19 BSPT thread size for British Standard Pipe Taper applications
• Bottoming chamfer allows threading to the base of blind holes
• 4-flute straight design provides balanced cutting and chip evacuation
• High speed steel construction for durability across ferrous and non-ferrous metals
• Bright, uncoated finish suitable for general-purpose tapping with cutting fluid
• Right-hand thread direction, standard for the majority of pipe thread applications

Compatibility

Designed for use in any manual tap wrench or machine tapping setup that accepts a 0.9843-inch round shank with a 0.5310-inch square drive. Suitable for cutting 3/8-19 BSPT internal threads per British Standard Pipe Taper specifications.

Installation Notes

This tap should be installed and operated by a qualified machinist or pipefitter familiar with tapping procedures. Always secure the workpiece and ensure the tap is properly aligned before applying cutting pressure to avoid tap breakage. Use a suitable cutting fluid or tapping compound to reduce friction and extend tool life. Follow applicable shop safety standards and manufacturer guidelines for spindle speed when used in a machine tapping application.
