Kennametal Carbide Flat Bottom Drills

FB Drills with Through Coolant for Flat-Bottom Applications

Primary Application

B707_FB Series Solid Carbide Drills are productivity tools that combine two operations in one:
 1) Eliminate the 180° end mill in flat-bottom drilling or when preparing an inclined or curved surface for drilling.
 2) After full cylindrical engagement, the drill runs at normal solid carbide drilling parameters.

The B707_FBS Series with the new uncoated KN15™ grade now offers the same advantages for drilling in non-ferrous materials, such as aluminium, copper, and brass. The B707_FBL Series is designed for applications in stainless steel and high-temperature alloys.

Features and Benefits

Unique FB Drill-Point Design

  • Two effective cutting edges over centre enable high feed rates.
  • Creates a true flat-bottom hole from O.D. to centre.
  • Four-margin lands improve hole straightness and roundness providing good alignment even in cross holes.

Straight Cutting Edge

  • Guarantees a true 180° hole ground.
  • Rake angle correction improves chip control.

Customisation

  • Intermediate diameters available as semi-standards.
  • Length variations available as semi-standard:
    • B706_ 1,5 x D
    • B708_ 5 x D
    • B709_ 8 x D
  • Other length variations and step drills are available as engineered solutions.

KC7315™ Grade on B702_FBG and _FBL

  • Enables high drill-like penetration rates and superior tool life.

KN15 Grade on B707_FBS

  • The uncoated grade prevents built-up edge reducing the risk of fracture.
  • The highly polished surfaces ensure superior chip evacuation even when low-pressure coolant or MQL is applied.
