Solid Carbide Flat Bottom Drill for Non-Ferrous Materials
Material Number100161601
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.
