Our vast assortment of Diamond CNC Finger Bits is intended for CNC machines, fabrication centers, and radial-arm machines. Fingers bits are one of the most common CNC tools used being employed to mill material and cut any type of curve in stone. We provide different types of finger bits to make fast, accurate, and enduring cuts in any material or job. Specifically, we offer:

Persons having a Conventional personality type "dominate" this environment. There are more of them than there are people of other personality types. For example, in an office of a bank or real estate company there will be more persons having a "Conventional" personality than there will be people who have a Artistic type.

Large selection of finger bits for all-natural stone, quartz, engineered stones, natural quartzite, ceramic and ultra-compact surfaces. (For the glass working: CNC glass cutting bit)

N.B. The cutting surface of a finger bit is always “on the side”. Never plunge a finger bit into a material in the Z-direction, only use a lateral motion in the X-Y plane. To plunge from top to bottom, use an interchangeable 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 vast assortment of bits available. Consult the following chart for assistance:

Remember, 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, however, we also have interchangeable bit tips with an M10 or M12 thread for the replaceable piece. Cylindrical shank or flange connections are also available.

As with other types of CNC tools, the following general rule applies: use an electroplated finger bit to work materials such as stone and marble; choose a sintered-segment finger bit to work hard stone 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. The bond must be chosen based on the material to cut:

Single-pass cutting if you want to get a better finish without having the steps visible and because it spreads the wear over a longer flute length, which means your tool will last longer. If you can cut in one pass and get a clean cut and good speed – do it. Multiple-passes cutting (incremental cutting) if you have a small CNC router and you need to cut without creating excessive tool deflection to minimize the risk of tool breakage or if the piece could move on the table.

The two work environments that are closest to the Conventional type are Realistic and Enterprising. The farthest away is the Artistic type.

Likes to work with numbers, records, or machines in a set, orderly way; generally avoids ambiguous, unstructured activities

Common rule for soft materials (if you are cutting granite or quartzite it could not be valid): It’s best to cut all the way through as the tip of a bit wears n-times faster taking n passes instead of one. The best bit life is had with top speed and most material removed per pass within the limit of cut quality and machine power

"Conventional" people create a "Conventional" environment. For example, they particularly value people who are orderly, and good at following a set plan -- good at working with written records and numbers in a systematic, orderly way.
