1 Choose the right tool (Diameter & Style)
2 Make sure your machine meets the tool requirements for speed and power
3 Make sure your machine meets the requirements in axial force
4 Assemble the tool holder correctly
5 Insert the Formdrill into the tool holder and tighten the nut very tightly
6 Insert the tool holder in the machine spindle
7 Clamp your work piece securely
8 Consult our wizard page for machining depths and feedrates
9 Lubricate the tool
10 Perform the drilling operation
11 When depth is reached make sure the tool retracts as fast as possible (no dwelling!)
12 Observe cycle time and drill color
13 Adjust when needed the speed and feedrate (Step 8). To much heat: Lower Rpm or increase feedrate or both
Working with Flat style drills
Attention: A hot chip is produced - use a guard to protect machine operator and surroundings
When a Flat style Formdrill is used you need to accelerate the feedrate just before the cutting starts: See video
This acceleration will increase tool life of the cutters significantly
The length and shape of the produced chip is a good indication: See picture
