Scientific Cutting Tools TM620-11BSPP-A Thread Mill 1-11 Bspp

Product Description

The SCIENTIFIC CUTTING TOOLS TM620-11BSPP-A is a straight flute thread mill designed for cutting 1-11 BSPP (British Standard Pipe Parallel) threads in both external and internal applications. Built from submicron-grade solid carbide and coated with AlTiN+, this tool delivers thermal resistance and wear performance in demanding CNC milling operations. With 5 flutes, a 0.62 inch cutting diameter, and a 1.125 inch length of cut, it is suited for threading operations where rigidity and thread accuracy are critical. Machinists and tool-and-die professionals install this mill on CNC machining centers for production and job-shop work.

This thread mill is used in applications requiring BSPP thread forms, commonly found in hydraulic fittings, pneumatic components, and fluid-system hardware produced for export or international markets. The straight flute geometry makes it effective in materials that generate short chips. With a 5/8 inch shank diameter and 3.5 inch overall length, it fits standard ER and end mill collet systems on vertical and horizontal machining centers. No coolant-through capability is present, so flood or mist coolant is applied externally during operation.

Key Features

• Cuts 1-11 BSPP threads in both external and internal configurations in a single tool
• Submicron-grade solid carbide construction for rigidity and edge stability
• AlTiN+ coating provides high-temperature oxidation resistance and extended tool life
• 5 straight flutes with 0.62 inch cutting diameter and 1.125 inch length of cut
• 3.5 inch overall length with 5/8 inch shank for standard collet compatibility
• No staggered tooth design - consistent chip formation in appropriate workpiece materials

Compatibility

Designed as an OEM-style thread milling solution for CNC machining centers equipped with standard collet toolholders accepting a 5/8 inch shank diameter, used in BSPP thread-form applications.

Installation Notes

Installation and operation should be performed by qualified CNC machinists familiar with thread milling toolpaths and G-code programming. Secure the shank fully in a balanced collet holder and verify runout before cutting. Flood or mist coolant should be directed at the cutting zone, as this tool does not have coolant-through capability. Follow the machine tool manufacturer and cutting tool guidelines for spindle speed, feed rate, and helical interpolation parameters appropriate to the workpiece material.
