High Speed Steel Tip Welded Internal Threading Tool Bits – Model 52

This High Speed Steel Tip Welded Tool Bit is a precision internal threading tool, Model No. 52, engineered for cutting accurate internal threads on lathes. The HSS tip is securely welded to a robust steel shank, combining sharp cutting geometry with the durability required for heavy-duty machining operations.

Ideal for marine engineering workshops, ship repair facilities, and general machine shops, this internal threading tool bit cuts clean threads in both blind and through holes. It is commonly used for producing or re-machining internal threads on low-alloy steels, carbon steels, and non-ferrous materials. The tool bit is easy to mount and delivers reliable performance at standard lathe speeds.

Listed under IMPA 633071, this cutting tool is a valuable addition to ship stores and offshore maintenance inventories. The HSS tip retains hardness at elevated temperatures, allowing repeated internal threading tasks without frequent replacement.
