Kennametal DFR Indexable Drill Inserts

Drill Fix™ DFR™

Drill Fix DFR offers maximum feed rates at diameter range 12,5–24mm at 2 x D, 3 x D, and 4 x D applications. Using rectangular-shaped inboard and outboard inserts enables soft starting cuts and short chips as well as enabling higher feed rates than small-size symmetrical-trigon or square inserts. Drill Fix DFR's low cutting forces provide long tool body life and highest stability at smallest sizes.

Furthermore, these inserts enable soft starting cuts and short chips. The low cutting forces of a Drill Fix DFR provide long tool body life and highest stability at smallest sizes.

Features and Benefits

Productivity and Profitability

  • Achieve highest feed rates with rectangular-shaped inserts
    that offer a soft starting cut and highest stability.
  • Use X-offset on turning machines to adjust the drill diameter,
    eliminating the need for specials in many applications and on
    machining centres, to reach tolerance optimisation.
  • Same insert size is used in each pocket, reducing inventory costs.


  • Diameter range covering 12,5–24mm.
  • 2 x D, 3 x D, and 4 x D L/D ratios as standard.
  • Various shanks as standard available: WD, SSF, and new KM-TS™.
  • Multiple insert grades and geometries available.
  • Use where feed rates are the limiting factor.
  • Apply at straight holes, inclined entries and exits, interrupted cuts, and rough or welded entry surfaces.
  • Eccentric chuck available as standard.


  • Highest stability at smaller sizes due to rectangular-shaped insert.
  • Same insert can be used as inboard or outboard insert.
    No risk of mixing up inner and outer insert.
  • Low cutting forces resulting in long body tool life.


  • Intermediate diameters available as semi-standards.
  • Engineered solutions available.
  • Multistep drills available upon request.
  • Left-hand version available.
