What materials are these CNC Core Bits designed for?
Porcelain slabs, sintered slabs (Dekton®, Neolith®), crystallized glass and other vitreous materials.
What thread do they use?
1/2" gas thread, the standard fitment for CNC stone tool holders.
What is the maximum RPM?
4,000 RPM. Do not exceed.
Why is bottom-side blow-out a concern?
Most CNC fabrication of porcelain and sintered slabs is performed upside-down, so the bit exits through the visible face. The Alpha® matrix is engineered to keep that exit clean.
Can these be used dry?
No. CNC Core Bits require continuous water through the tool holder for cooling, slurry removal and bit life.
What traverse speeds should I use?
Approximately 1-1/4" (30mm)/min while cutting through 3/4" stock, reducing to 5/8" (15mm)/min as the bit exits to prevent blow-out.
