Nine9 99314- 4xD Super Drill: Ø16 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.

Cutting Insert

Fully ground dual-relief insert, for improved surface finish and higher feed rate.
Primary relief angle is to increase the toughness of the insert, secondary relief angle is to strengthen the axial feed rate.
Same insert for outer and inner insert.
Square insert with 4 cutting edges, reducing cost per insert.
Better surface finish.
Better diameter accuracy.
