Designed for engineers, buyers, tradespeople, hobbyists, and shop-floor operators, the Carmex Spiral Mill Threading Insert for BSPT (H63-11BSPTMT7) combines precision threading with versatile milling capabilities. Its spiral geometry supports smooth cutting at higher feed rates, helping reduce cycle times while maintaining strong thread quality across a range of components and machines—from compact centers to high-power milling setups.

With MT7 sub-micron inserts featuring a Titanium Nitride multi-layer coating (ISO K10–K20), this insert delivers durable wear resistance and broad material compatibility. It excels in threading, end-milling roughing, and finishing tasks, providing reliable performance across varied materials and production demands.

• Smooth, high-feed cutting: The spiral design enables a smooth cutting operation at high feed rates and reduces machining time, helping you finish jobs faster without sacrificing finish quality.
• Flexible insert arrangement with optimal indexability: Spiral fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures precise indexing for repeatable results.
• MT7 TiN-coated inserts for broad material compatibility: Sub-Micron MT7 inserts with Titanium Nitride multi-layer coating provide wear resistance across all materials, delivering longer tool life and reliable performance in threading and milling.

This combination translates to a streamlined workflow: fewer tool changes, predictable thread quality, and consistent finishes across threading and milling passes. The reliable indexing and vibration reduction contribute to cleaner BSPT threads, better surface finish, and greater confidence during production runs.
