Allied Machine TN150K-BSPP11 Carbide Thread Mill Insert Bspp

Product Description

The ALLIED MACHINE AND ENGINEERING TN150K-BSPP11 is a carbide thread mill insert designed for cutting BSPP (British Standard Pipe Parallel) threads at 11 teeth per inch (TPI). Carrying an AM210 coating and finish, this TN-style insert is built for both internal and external threading applications. The insert measures 0.14 inches thick (3.56 mm) and is engineered for use in thread milling operations where precision, tool life, and consistent thread form are critical. Machinists and tooling technicians working in precision manufacturing, fluid system component production, and general metal fabrication rely on this insert for repeatable BSPP thread profiles.

This insert is suited for thread milling on parts that require BSPP thread forms, commonly found in hydraulic, pneumatic, and pipe fitting components. The TN150K-BSPP11 handles both internal and external threading in a single insert style, making it a practical choice for shops producing fittings, manifolds, and ported housings. It is a non-conical insert, appropriate for straight-wall BSPP thread forms. The AM210 finish provides enhanced cutting performance on a range of ferrous and non-ferrous materials.

Key Features

• Carbide construction for extended tool life in demanding threading operations
• AM210 coating and finish for improved surface finish and cutting efficiency
• BSPP thread standard, 11 TPI for British Standard Pipe Parallel thread forms
• Capable of both internal and external threading with one insert style
• Non-conical profile for straight-wall BSPP thread applications
• TN insert style for secure seating in compatible thread mill toolholders

Compatibility

Designed as an OEM-style replacement or direct-use insert for thread milling tools that accept TN-style carbide inserts configured for BSPP 11 TPI threading.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with thread mill insert seating and torque procedures. Always power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating the new insert. Follow the thread mill toolholder manufacturer guidelines for proper insert orientation and clamping to ensure accurate thread form and safe operation.
