Hertel R867363-S 1/2-14 Rp Bsprp Pipe Tap Bottoming 4 Flute Hss

Product Description

The HERTEL R867363-S is a British Standard Pipe tap designed for cutting internal Rp (BSPRP) parallel pipe threads in a single-pass or final-pass threading operation. Built from high speed steel with a bright finish, this bottoming-chamfer tap is suited for threading operations where the tap must reach close to the bottom of a blind hole or fitting port. With 4 flutes and a regular hook geometry, it handles a range of materials common in pipe fitting, valve, and manifold work. At 3.125 inches overall length and a 1.375-inch thread length, it fits standard tap handles and machine setups used in trade shops and field fabrication.

This tap is used wherever 1/2-14 Rp BSPRP internal threads are required, including hydraulic fittings, pneumatic manifolds, fluid control valves, and plumbing components that follow British Standard parallel pipe thread specifications. It is appropriate for both manual hand-tapping operations and machine tapping setups in maintenance, repair, and fabrication environments. Licensed plumbers, pipefitters, millwrights, and machinist tradespeople handling British-standard threaded components are the typical installers.

Key Features

• Bottoming chamfer allows threading to within a few threads of a blind hole bottom
• High speed steel construction provides durability across a range of workpiece materials
• 4-flute design offers balanced cutting action and chip clearance
• Bright finish indicates an uncoated, as-ground tool surface suited for general-purpose tapping
• Regular hook geometry provides stable cutting performance in hand and machine tapping
• 1/2-14 Rp BSPRP thread standard for British Standard parallel pipe thread applications

Compatibility

Designed for cutting 1/2-14 Rp BSPRP parallel internal pipe threads in components conforming to British Standard pipe thread specifications. Suitable for use with standard tap wrenches and machine tap holders sized for this tool diameter and shank.

Installation Notes

This tap should be installed and operated by a qualified machinist, pipefitter, or plumber familiar with pipe thread tapping procedures. Always secure the workpiece and use appropriate cutting fluid to extend tool life and improve thread quality. For bottoming operations in blind holes, back the tap out periodically to clear chips. Inspect the tap for wear or chipping before each use and replace if cutting edges are degraded.
