    • Flat bottom drills with through coolant.
    • Application-specific SC drills that combine two operations in one:1) Eliminate the 180 Deg. 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.
