Frequently Asked Questions
Q: What CNC machines are compatible?
A: Compatible with standard CNC routers and engraving machines with ER11 or ER16 collets accepting 6mm or 8mm shanks.
Q: Which tip size should I choose?
A: Smaller tips (0.2–0.4mm) are ideal for fine detail and thin line engraving. Larger tips (0.6–1.0mm) suit broader strokes and faster material removal.
Q: What angle is best for stone carving?
A: 60° produces the finest, deepest V-groove. 90° gives a wider, shallower cut suitable for bold lettering. 70° is a versatile mid-range option.
