The cutting speed relates to the periphery inserts, The feed rate depends on the load of the center pilot insert. The best condition will create short cutting chips. The feed rate can be applied ± 25% of the recommended value depended on the shape of the cutting chips. Be careful to monitor the spindle power consumption! When the spindle load is 15% higher than starting power consumption, please change the periphery insert to next new cutting edge and change a new center pilot insert. Minimum coolant pressure is 10 bar (about 150 psi.). Internal coolant is required. Increase 20% of the cutting speed and the feed rate for horizontal spindle machine. For the CNC lathes, maximum miss-alignment of drill center and spindle center is ±0.05 mm, it is not necessary to drill center hole in advance.

12 Ø10 Super Drill Smallest indexable drill from 10mm. 4 cutting edges per insert, same insert for outer and inner insert. ~ Ø30 SMALLEST DIMENSION 3xD : Ø10 to Ø30 mm. 4xD : Ø16 to Ø30 mm. SMALLER CUTTING CHIP The center and peripheral inserts are positioned in order to divide the cutting chips into smaller spiral shape. It helps the cutting chip to be removed faster and easier. Designed for high productivity, high speed cutting. Coolant supply is needed. BETTER SURFACE FINISH AND BETTER DIAMETER ACCURACY Special insert positioning to balance the cutting forces, better surface finish and diameter accuracy are achievable. 9
