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.
