ATORN 180° high-performance drill, SC TiAlN, 5xD 14.0 mm x 14 mm x 122 mm

Application

For producing drill holes with a 180° hole base in one operation

Execution

• Heavy-duty solid carbide drill with 180° precision grinding and drill heels
• Recommended pilot drill bits under art. no. 11181.

Advantage

• drilling and counterboring in a single work step at high cutting speed
• Innovative geometry ensures good chip removal

Notes

The maximum permissible inclination of the drilling surface is 15° correction factor = 0.25
For spot drilling, multiply feed f [mm/U] by correction factor Kf

• Spot drill with reduced feed until the tool cuts to 0.25xD over the total ø


• For angled spot drilling: Retract at double feed rate f [mm/U]


• After spot drilling at reduced feed rate (correction factor), drilling continues at feed rate f [mm/U] according to recommended cutting data without correction factors


• Setting a pilot hole is recommended for drilling on flat surfaces.
