CNC core drills for Granite, Quartz, Engineered Stone
Continuous rim core bits suggested when you need a highly smooth, accurate holing and chip-free drilling
Thanks to the continuous rim these core drills give you a slower cutting if compared with a segmented ring core bits, but they ensure a clean cut even when exiting the material at the end of the holing. It has a little bit weaker structure because it’s thinner and with a finer diamond.
We suggest the use of a continuous ring core bit only with a precise CNC machine with no vibration. We do not recommend the use of this tool in a manual contouring machine or column drill where the spindle could have too many vibrations and the core bit will be worn-out very fastly.
You can buy continuous rim core bits in different diameters, from 10mm up to 60 mm, all 1/2″ gas fitting.
On request, it is possible to supply the continuous rim core bits in other diameters
Suggested parameters for the various models:
| Code | Size | Rpm | Feed |
|---|---|---|---|
| APF11010 | Ø10 X 50 mm | 2500-3000 | 50-100 mm/min |
| APF11020 | Ø20 X 50 mm | 2500-3000 | 50-100 mm/min |
| APF11025 | Ø25 X 50 mm | 2600 | 50-100 mm/min |
| APF11030 | Ø30 X 50 mm | 2400 | 40-50 mm/min |
| APF11035 | Ø35 X 50 mm | 2200 | 40-50 mm/min |
| APF11040 | Ø40 X 50 mm | 2200 | 40-50 mm/min |
| APF11050 | Ø50 X 50 mm | 2000 | 40-50 mm/min |
| APF11060 | Ø60 X 50 mm | 2000 | 40 mm/min |
