SE Four-Margin Drill • Coolant • Steel
The SE solid carbide drills are enhanced with superior chip evacuation ensuring long tool life and consistent performance. In applications demanding high accuracy, consistent hole straightness, and excellent metal removal rates, such as in connecting rods (conrods), our application-specific SC drill for mid-L/D applications excels. Featuring an SE drill point design with a sculptured edge, these drills enable high feed rates. Moreover, our multi-layer grades allow for higher cutting speeds ensuring efficient steel machining operations.
