Seco’s Crownloc Plus exchangeable tip drills takes holemaking to the next level by increasing output and decreasing machining costs. The drill saves users money by incorporating several new features that yield high quality holes with less tool inventory and no regrinding or resetting costs, the company says. The line includes options for drilling holes ranging from 0.472” to 0.787” in diameter with 3×D and 5×D cutting depths.
 
Featuring optimized geometry with TiAIN coating, the drill has enhanced entering capabilities, as well as excellent chip evacuation and wear resistance in a variety of materials, including stainless steels and superalloys. The line’s strong, polished drill body design includes deep and wide flutes and a high-strength locking interface.
 

For best results, the company recommends using these exchangeable crowns with the following holders: the Weldon DIN 1835 B/DIN 6535 HB, Type 5834 hydraulic chucks (for cylindrical, -R1 shanks only) or Type 5603 shrinkfit holders (for cylindrical, -R1 shanks only). In terms of coolant mix, the company recommends an emulsion mix between 6 percent and 8 percent. However, when drilling in stainless steels, superalloys and high strength steels, the recommended mix is 10 percent.
