CNC Finger Bits
Diamond CNC Finger bits for stone fabrication (for cutting marble, granite, ceramics, and synthetic materials such as Lapitec, Dekton, or Neolith
As with other types of CNC tools, the following general rule applies: use an electroplated finger bit when working materials such as stone and marble; choose a sintered-segment finger bit when working hard stones such as granite, lava stone, basalt, or quartz.
The bonding matrix is a very important factor when choosing the most appropriate sintered-segment finger bit. Choose the bond based on the material to be cut:
- Use a very soft bond (FB23) when cutting quartz, engineered stone, ceramic, Dekton, Laminam, Lapitec, Neolith…
- Use a soft bond (FB3) when cutting hard quartz
- Use a medium hardness bond (FB2) when cutting medium-hardness materials
- Use a hard bond (FB1) when cutting soft materials
Our wide range of Diamond CNC Finger Bits is intended for CNC machines, fabrication centers, and radial-arm machines.
Fingers bits are one of the most common tools used with CNC machines since they are used both to mill away material and cut any curve in stone.
We provide different types of finger bits to make fast, precise, and long-lasting cuts in any material. These are, specifically:
- Electroplated for marble
- Sintered with a hard bond for soft stone
- Sintered with a soft bond for hard granites and engineered stone
- Sintered with a very soft bond designed for the hardest stones like quartzite
Actually, a soft material requires a hard-bond finger bit whereas a hard material requires a soft bond bit.
1/2” gas is the standard connection, connecting however our replaceable tip bits come with have an M10 or M12 thread for the replaceable piece. Cylindrical-shank or flange connections are also available.
The cutting surface of a finger bit is always “on the side”. Never enter a bit into a material following a Z-shaped motion, but only use a lateral motion in the X-Y plane. To enter material from top to bottom, use the replaceable finger bit tip, or the segmented finger bit specifically designed for incremental cuts.
Choosing the right sintered finger bit for a particular job can be confusing due to the large variety of bits available. Consult the following chart for assistance:
