Proposed solution
Proposed solution
The HEULE representative proposed a standard VEX-P drill-chamfering combi tool. This tool allows to machine the complete hole in one setting and without any tool change.
VEX-Tool: GH-Q-O-4206
Drill: P-P-D-1500-1H
Chamfer blade: GH-Q-M-03846
Machining parameters:
- Cutting data drilling:
Speed: 1500 rev/min.
Feed: 0.2 mm/rev. - Cutting data chamfering:
Speed: 1000 rev/min.
Feed: 0.1 mm/rev.
