| The P geometry is recommended for drilling in steel and replaces the need for regrindable tools such as solid carbide drills and brazed drills. | About Crownloc: | 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. | Crownloc is available in a large range of optimized tip geometries for different applications and workpiece materials. | It reduces stress in the machined surface and minimizes burr creation at the holes exit by minimizing cutting forces, high heat generation and workpiece hardening. | Diameter range 10 - 25.99 mm (.393 - 1.023 inch).
