Please use in a machine with precise spindle rotation. Tight clamping is critical.
2. The indicated feeds and speeds are for drilling with water-soluble fluid. 3. Please use water-soluble high density fluid (less than 20 times dilution). 4. These tables are applicable for less than 3xD deep drilling operations. When drilling deeper than 3xD, please peck every 0.25-0.5xD accordingly.
5. The run out with a drill in the spindle should be less than 0.0001”. 6. OSG’s Shrink Fit System is the recommended tool holder for these drills. For machines that cannot achieve the speeds indicated in the above table, please set rotation as high as possible. Tool life may be decreased.
