CNC and shop tips for diamond finger bits used on engineered quartz sink openings.
Engineered quartz is dense and abrasive, so finger bits must balance sharpness with bond life. Too soft a bond sheds diamonds early; too hard a bond burns the edge. Protec Tools finger bits are tuned for wet CNC sink cutouts where dimensional accuracy and chip-free walls matter to fabricators.
Process tips that protect edges
- Use adequate water at the bit and keep chips flushed
- Step down in multiple passes instead of one deep plunge
- Dress the bit when cutting speed drops suddenly
- Confirm template offsets before the production nest
For OEM buyers, share your common sink radii and quartz brands so bit geometry can be frozen before the first container order.
