Engineered for reliability and control, this slot drill minimizes deflection in shallow slots while delivering a clean, precise finish. The powder-metallurgy HSS-E composition enhances wear resistance for longer tool life under demanding cutting conditions. The 30° helix facilitates smooth chip evacuation, helping to reduce heat buildup and extend insert life in copper alloys and free-machining steels. With its Weldon 10 mm shank, it locks securely in collets and holders, ensuring stable cuts even at depth. DIN 327 D compliance guarantees compatibility with standard tooling setups, making this drill a dependable choice for shops needing repeatable performance in tight milling operations.
