Note: 1. The speeds and feeds in the table above apply when drilling on a flat surface with water-soluble coolant. 2. When using non-water soluble oil or water-emulsifiable (over 20 times dilution), reduce cutting speed by 30%. 3. Use a rigid and precise machine and holder. 4. Please minimize tool overhang as much as possible during machining. 5. Adjust the rotational speed and the feed rate in accordance with conditions such as the machining shape, machine rigidity, or work holding. 6. Please set up the drill so that the runout of the cutting edge is under 0.0004 in. 7. When machining an inclined plane,adjust the rotational speed and the feed rate in accordance with the angle of the incline (β). • When the machining incline angle(β) is less than 30°, please reduce the feed to 40-60%. • When the machining incline angle(β) is over 30°, please reduce the speed to 60-80% , the feed to 40-60%. 8. Please use step drilling in pilot holes to improve cutting chip separation. 9. If it is necessary to ensure the locating precision of the hole to be machined, adjust the rotational speed and the feed rate as indicated above (in accordance with the machining precision requirement).
