Crownloc® Plus Tip drills for efficient, cost-effective holemaking.
Crownloc® Plus is a range of exchangeable tip drills that take holemaking to the next level by increasing output and decreasing machining costs.
The drills save users money by incorporating several unique features that yield high quality holes with less tool inventory and no regrinding or resetting costs. An optimized geometry with TiAIN coating, enhances Crownloc Plus’ entering capabilities, as well as 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 that enables users to simply change the crown rather than the entire tool due to wear.
Crownloc Plus is available in P geometry for general applications, M geometry for excellent performance in high temperature alloys, titanium, titanium allows and stainless steel, and L geometry for demanding applications such as angled exits. The line includes options for drilling holes ranging from .472" to .787" in diameter with 3xD, 5xD and 8xD cutting depths.
For best results, use 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 high pressure collet.
Coolant mix should be 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.
