Crownloc® is a range of exchangeable tip drills designed to offer high-quality holes at a lower cost. Matching the quality of high precision drills, Crownloc® uses replaceable crowns to eliminate the need for and cost of regrinding. This guarantees consistently higher performance and tool life while also reducing the number of drills required in inventory. Crownloc® features a unique clamping design with a precision ground interface of interlocking V-grooves to allow high cutting speeds and ensure rigidity and exact repeatability of positioning of each crown. Long land margins provide excellent guidance to ensure high hole quality and self-centering geometry eliminates the need for center drilling operations. Double coolant holes through the crown permit a high volume of coolant to reach the cutting edges. The result is safer chip evacuation and longer tool life.
