Description

Specs

  • Quantity: 1 piece
  • Length: 12 inches
  • Material: High-Speed Steel (HSS)
  • Type: Aircraft extension drill bit
  • Designation: DWDA/C

Features

  • Long-reach design provides extended access to deep or recessed holes in metalwork.
  • HSS construction delivers durability and sharpness for repeated drilling in steel and other metals.
  • Aircraft extension geometry supports steadier guidance in tight spaces, reducing wandering.
  • DWDA/C designation identifies the bit family and its intended usage within standard drill setups.
  • Ideal for single-piece long-hole drilling tasks where shorter bits would require multiple passes.
  • Use cases: accessing deep pockets in automotive frames, machine tooling, and fabrications with limited clearance.
  • Practical tips: use light lubrication to manage heat; ensure the bit is properly secured in the chuck before starting; start with a pilot hole if drilling through harder substrates.
