The Center Drill BS-6 is a long pilot combination center drill, manufactured as per British Standard BS 328 Type 6.
This tool is specially designed for deep center hole drilling and accurate alignment in components where a longer pilot depth is required.
Made from premium High-Speed Steel (HSS) , the BS-6 provides excellent rigidity, heat resistance, and dimensional accuracy.
It features a 60° included angle with an extended pilot, allowing improved guidance and concentricity during turning and grinding between centers.
The BS-6 is ideal for heavy-duty CNC machining, precision turning, and shaft center hole preparation.
