Seco Introduces Crownloc PlusApril 1, 2012
Seco's new Crownloc Plus exchangeable tip drills are designed to increase output and decrease machining costs, the company said.
"Crownloc Plus incorporate several new features intended to yield high quality holes with less tool inventory and no regrinding or resetting costs," said a company spokesperson. "The line includes options for drilling holes ranging from .472 to .787 inches in diameter with 3xD and 5xD cutting depths.
"Featuring new optimized geometry with TiAIN coating, Crownloc Plus 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, Seco 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, Seco recommends an emulsion mix between 6 and 8 percent; however, when drilling in stainless steels, superalloys and high strength steels the recommended mix is 10 percent.
