High-Performance Solid Carbide Drills

180° Flat-Bottom Drills • Through Coolant

Features and benefits
  • Flat bottom drills with through coolant.

  • Application-specific SC drills 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.

  • Unique FB drill-point design with two effective cutting edges over center enable high feed rates.

  • Creates a true flat-bottom hole from O.D. to center.

  • Four-margin land design improves hole straightness and roundness and provides good alignment, even when drilling cross holes.

  • Three grades-geometry-combinations available to cover most common materials.
