Want some guidelines on how to improve performance of drill-bits? Head to our blog section or explore our upcoming events and exhibitions around the globe. Here is a quick overview of expos where you can find us next. Hope to see you there:
Stroke Speed: 2 – 10 strokes / minute (the stronger the cardboard the slower the speed)
Pile Height: approximately 35 mm
RPM: as above
Recommended: PVD coated WCC Tungsten Carbide, TiN
Drilling on Plastic Films
Stroke Speed: 2 – 10 Strokes / Minute
Pile Height: approximately 35 mm
Recommended: PVD Coated Hard Carbon, Futura Nano
Drill Bit Diameter
Spindle Rotation Speed
4 mm
1,350 rpm
5 mm
1,100 rpm
6 mm
900 rpm
7 mm
770 rpm
8 mm
680 rpm
9 mm
600 rpm
With plastic films
larger diameters are easier to drill than smaller ones
drill bit cooling and lubrication is essential
the chips have to be cleaned out of the drill bits right after finishing the job by drilling 3 – 4 times through a 50mm pile of offset paper
Drilling on Recycled Paper
The paper drill bit becomes blunt much faster when drilling on recycled paper than, for example, with offset paper. In order to enhance results, they must be changed or sharpened at shorter intervals. Drill Bit cooling and lubrication is important to achieve a certain drill life and to avoid drill breakage.
