Choosing the Right Finger Bit

Selecting the proper bond is essential for maximizing cutting speed and tool life.

• Soft bond finger bits perform best on hard materials such as granite and Dekton®, continually exposing fresh diamonds for aggressive cutting.
• Hard bond finger bits are ideal for softer materials, helping extend tooling life by slowing diamond exposure.
• Electroplated finger bits provide excellent performance on marble and other softer natural stones where clean cutting and finish quality are important.

Using the proper bond and segment design helps improve productivity while reducing tool wear and minimizing edge chipping.

Whether you're producing custom countertops or operating a high-volume CNC fabrication shop, Diamut CNC Finger Bits provide the speed, precision, and reliability professionals expect.

Frequently Asked Questions

What materials can Diamut CNC Finger Bits machine?
These finger bits are designed for granite, quartz, marble, engineered stone, and Dekton®, making them an excellent all-purpose choice for countertop fabrication.

What is the difference between hard bond and soft bond finger bits?
A soft bond is recommended for hard materials like granite and Dekton® because it continually exposes fresh diamonds. A hard bond is better suited for softer materials, helping extend the life of the tooling.

What are the 5-segment and 7-segment spiral designs?
Both spiral designs promote efficient material removal and smooth cutting. Depending on the application and material, fabricators can choose the configuration that best fits their production requirements.

Can these finger bits be used for sink cutouts?
Yes. Diamut CNC Finger Bits are ideal for sink cutouts, edge truing, interpolation, hole enlargement, and other common CNC machining operations.

Why choose the electroplated version for marble?
The electroplated version is specifically designed for marble applications, providing smooth cutting performance and excellent finish quality on softer natural stone materials.
