KenDrill™ HPS • 3 x D • Internal Coolant • Straight Shank • Metric
Solid Carbide Drill for Non-Ferrous Materials
Features and benefits
- HPS Beyond™ drills for aluminum machining with MQL.
- Material-specific SC drill with highly polished surface that ensures superior chip evacuation and avoids built-up edge, even when MQL coolant is applied.
- Sharp cutting edge enables higher tool life in aluminum and other non-ferrous materials.
- HP point enables high feed rates by progressive rake angle.
- Enlarged flute design enables fast chip evacuation and high metal removal rates.
- Enlarged chamfer on back end according to DIN 69090-3 (round cylindrical for MQL) to ensure optimum coolant flow without leakage.
