About The Product
Massive Savings on Diamax Cyclone Ultra CNC Finger Bits, 40 mm, 20 mm diameter, Wet Only, which is engineered for demanding CNC machine stonework, with durability that professionals notice on first use. If you're processing engineered stone, granite, or porcelain tile, this finger bit's 40 mm length and 20 mm diameter strike a practical balance - aggressive enough for fast feed rates but sized to control fine shaping and detail. The surface cut stays consistent thanks to the premium diamond matrix, especially when used at up to 4500 RPM, max as specified.
This bit comes with a 1/2 inch gas arbor, which fits most commercial CNC machines configured for automated wet operations. It's exclusively designed for wet-only applications, which extends tool life and keeps debris under control during extended fabrication runs. Professionals value the bit for its reliable cut-off rate and minimal chipping when used with engineered stone backsplashes or high-density granite.
You will see different spindle speeds recommended for different substrates, but the manufacturer lists 4500 RPM as the upper safe limit. If your workflow calls for a tool that reduces downtime, these finger bits are known for outlasting standard options, especially when properly cooled. There are no additional adhesives or accessories required; just mount and go - as long as your CNC is set up to handle wet bits in this diameter and arbor size.
These come from Diamax, which is a recognized provider of pro fabrication tooling. If you need a reliable supply chain, inventory is in stock now, so contractors can bulk order and expect consistent fulfillment. Browse more core and finger bits for CNC applications here.
