| 1 | Choose the right tool (Diameter & Style) |
| 2 | Make sure your machine meets the tool requirements for speed and power |
| 3 | Assemble the tool holder correctly |
| 4 | Insert the Formdrill into the tool holder and tighten the nut very tightly |
| 5 | Insert the tool holder in the machine spindle |
| 6 | Clamp your work piece securely |
| 7 | Make sure the distance between work piece and drill bit is limited |
| 8 | Set the correct spindle speed for the tool |
| 9 | Set the correct drilling depth |
| 10 | Lubricate the tool |
| 11 | Perform the drilling operation in a constant downward motion (no dwelling!) |
| 12 | When depth is reached retract the tool as fast as possible |
| 13 | Observe cycle time and drill color |
| 14 | Adjust when needed the speed (See step 8 & 11) |
| 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 |
