RUHI Center Drill BS5 X 100 mm Long

The Center Drill BS-5 × 100 mm is a long-length combination center drill and countersink tool, manufactured as per British Standard BS 328 Type 5.
It features a 90° included angle, specially designed for countersinking, deburring, and precise center hole machining in a single operation.

Made from premium-grade High-Speed Steel (HSS) or Solid Carbide, this long series BS-5 drill offers superior edge strength, wear resistance, and thermal stability, making it ideal for high-speed and heavy-duty machining.
Its protective chamfer geometry ensures a clean finish and prevents tool tip chipping during deep centering or large component work.

With an overall length of 100 mm, this long series version provides extended reach, making it suitable for deep or recessed center holes, countersinking large shafts, or finishing edges on CNC, lathe, and drilling machines.
