INDEXABLE DRILLS USER GUIDE Setup of Non-Rotating Drills Machining Conditions Make sure the center line of the drill is aligned with the spindle center line. It is recommended to verify the setup Optimizing Chip Shape for DR Drills according to the instructions shown below. DR-06 L L1 h2 h1 D-0.3 (mm) DT GF D+1 (mm) Under regular conditions it is possible to adjust the center line of the drill (X-axis of the machine) in order to change hole diameter size. General use For ISO – P/M/K/H/S For low up to medium materials feed rates For medium up to For ISO – P material high feed rates L – close L – open H2 – highH2 – lowL1 – small CORE L1 – medium H1 – deep H1 – shallow 1 Drill a hole 6 mm deep with the drill center AL HD line aligned with the spindle center line.2 Check the existing core. If there is no core, check the alignment of the Y-axis of the drill and spindle. Correct by checking the adapter or adjusting the Y-axis. 3 Check that the hole diameter equals the drill diameter +0.0- +0.2 mm. If not, adjust the X-axis. 4 Note: In some operations, part of the core may break. For medium up to For low up to medium If this occurs, use finger contact to verify if any high feed rates feed rates core remains For ISO – N material For ISO – P material L – open L – openH2 – highH2 – high Warning: As the drill goes all the way through L1 – non L1 – non a workpiece, it ejects a disc.
