Instructions for use
- 200 rpm – recommended spindle speed
- 400 rpm – possible spindle speed, but increased wear of drill bit or service life losses (about 7-9%) can be expected
- 600 rpm – not recommended, significantly increased wear
- 35 – 45 kg: optimum feed pressure
- “cutting (scratch) noise” should be heard
- “drilling test holes” (preferably to be drilled in an oddment of the tile)
- 1. Precise centering with light pressure
- 2. Turn on the drill
- 3. Full feed pressure
- 4. Reduced feed pressure in the exit of the hole (drilling through the tile)
Please avoid full feed pressure on the drill bit when the drill is not operating. Risk of breakage!
- If despite the recommended spindle speed (rpm) and optimum feed pressure is no cutting (scratch) noise, the service life of the drill bit is achieved
- Low feed pressure or too high spindle speed (rpm) -> early end of tool life
- Please avoid tilt and swivel motion during drilling operation. Risk of breakage!
