Bi-Metal Extended Bit

Extended drill bits were used by a rail industry customer in hand-assembly work to help workers to reach beyond structural members to attach materials. The cobalt drill taps and bits were costly, yet broke frequently during use. Factory management insisted that this consumable expense and the resulting downtime be reduced.

Solution

A bi-metal extended bit was proposed by American Friction Welding that will improve productivity and bring down material costs by attaching a 1018 carbon steel extension shaft into cobalt steel drill bits and taps.

The key features of the bi-metal extended bit are:

  • Strength more than full-length cobalt tool steel bits
  • Less likely to snap under tension at a range of work angles
  • Material cost brought down by reducing cobalt steel by 66%
  • High worker productivity with less down time

Conclusion

American Friction Welding application specialists work closely with customers all through the project. Design engineering assistance, process analysis and testing offer the ultimate cost solutions.
