RUHI Center Drill BS3 X 100 mm Long

The Center Drill BS-3 × 100 mm is a long series, double-ended center drill designed as per British Standard BS 328 Type 3 for deep centering and pilot hole drilling in recessed or long components.
This long version provides extra reach while maintaining dimensional accuracy and stability during machining, turning, and drilling operations.

Manufactured from premium-grade High-Speed Steel (HSS) or Solid Carbide, it ensures high hardness, wear resistance, and durability.
It features a 60° included drill angle with a protective chamfer, which prevents edge chipping and improves surface finish at the center hole.

The 100 mm overall length is ideal for deep center holes, large shafts, and components with restricted access, especially in CNC lathes, vertical machining centers, and precision toolrooms.
