SEFAS System
The SEFAS™ combination drilling system allows for centering, drilling, and chamfering in a single operation. The high-performance design and flexibility can be used to adapt the tool for varying hole geometries and provide full through-coolant capabilities. SEFAS chamfering bodies provide additional workpiece and workholding clearance during operations. The chamfer rings can be mounted to Kennametal hydraulic chucks for optimal drill performance and increased productivity. SEFAS chamfering inserts are available and can be used on various materials and with KenTIP™ or KSEM™ drills.
