Description

Specs

  • Diameter: #28 (0.1406 in / 3.57 mm)
  • Overall length: 6.0 in
  • Material: cobalt alloy (high-heat resistant cutting edge)
  • Package: 1 piece

Features

  • Extended reach: 6" overall length enables deep-hole drilling and access to recessed fasteners that standard bits cannot reach
  • Cobalt alloy construction: superior heat resistance and edge life when drilling harder metals, reducing premature wear
  • Long-bit geometry: optimized for applications requiring increased bit length and extended reach
  • Use scenarios: ideal for aerospace maintenance, automotive work, and industrial fabrication where long-access drilling is needed
  • Practical guidance: apply cutting fluid and use moderate feed pressure to manage heat and maintain edge integrity

Physical

  • Overall length: 6 inches
  • Nominal diameter: #28 (0.1406 in / 3.57 mm)
  • Construction: cobalt alloy drill bit with extension design for increased reach
