Combination Tools Combination Drilling Tools are customizable using standard components and combine centering, drilling, and countersinking into a single operation, increasing productivity by reducing cycle time Both the BF and SEFAS™ combination systems provide high flexibility to adapt the tool to varying hole geometries and provide full through-coolant capabilities. BF Combination Drilling System • Drilling, chamfering, and countersinking in one tool. • Uses solid carbide and modular KenTIP™ drills. • Covered drill diameter range .125-750" (3,4-18mm). • A specific range of drill diameters...

BF Combination Drilling System Primary Application Combines centering, drilling, and countersinking into a single operation, increasing productivity by reducing cycle time and number of tool changes. The modular design provides flexibility to adapt the tool to varying hole geometries in small- and medium-lot-size manufacturing. With its slim design and full-through-coolant capabilities, the BF combination system can be used even for deeper holes, critical materials, and with restricted workspace. • Reduce the number of tool changes and your cycle time by combining drilling and countersinking...
