Scorpion CNC Finger Bits

Fast-cutting CNC finger bits engineered for granite and other hard natural stones.

Looking for a CNC Finger Bit That Excels on Granite?

Scorpion CNC Finger Bits are designed to deliver fast, efficient material removal and exceptional tool life when machining granite and other hard natural stones. Featuring a soft bond diamond matrix, these professional-grade finger bits continuously expose fresh diamonds during cutting, allowing them to maintain aggressive performance on dense materials where harder bond tooling can become glazed.

Engineered for professional stone fabrication shops, Scorpion Finger Bits provide smooth cutting, reduced machine load, and cleaner finished edges while helping maximize CNC productivity. Their optimized bond and cutting geometry produce less noise and lower amp draw, allowing CNC machines to operate more efficiently during demanding machining operations.

Whether you're milling sink cutouts, enlarging holes, or preparing edges for profiling, Scorpion CNC Finger Bits deliver the performance fabricators rely on every day.

What Fabricators Use Scorpion CNC Finger Bits For:

• CNC sink cutouts
• Granite countertop fabrication
• CNC interpolation
• Enlarging drilled holes
• Material removal before profiling
• Radius and inside corner machining

  • 300–350 mm/min after break-in, depending on the material being machined

Why Soft Bond Tooling Works Best on Granite

Hard materials such as granite require a soft bond finger bit because the bond wears at a controlled rate, continually exposing fresh diamond particles. This allows the tool to maintain aggressive cutting action and prevents the bit from glazing over.

In contrast, softer stones typically require a harder bond, which slows diamond exposure and extends tool life when machining less abrasive materials.

Using the proper bond for the material being machined is essential for maximizing cutting speed, finish quality, and tooling life.

Whether you're producing custom countertops or operating a high-volume fabrication shop, Scorpion CNC Finger Bits deliver the speed, efficiency, and durability professionals demand.

Frequently Asked Questions

What materials are Scorpion CNC Finger Bits designed for?
Scorpion CNC Finger Bits are optimized for granite and other hard natural stones where a soft bond provides the best cutting performance.

Why does granite require a soft bond finger bit?
Granite is highly abrasive. A soft bond wears more quickly, exposing fresh diamonds throughout the cutting process and maintaining aggressive cutting performance without glazing.

What RPM should these finger bits be operated at?
Scorpion Finger Bits are designed to operate at 5,500 to 5,800 RPM for optimal cutting performance.

What feed rate is recommended?
During the break-in period, use a feed rate of approximately 200 mm/min for the first 2 meters. After the tool has broken in, increase the feed rate to approximately 300–350 mm/min, depending on the stone being machined.

What are the benefits of a properly matched finger bit?
Using the correct bond for the material results in faster cutting, cleaner finishes, lower machine amp draw, reduced noise, and longer overall tooling performance.
