Diamut Thin-Wall CNC Core Bits

Fast-cutting CNC core bits engineered for granite, marble, quartz, and Dekton with superior cooling and long tool life.

Looking for a High-Performance Thin-Wall CNC Core Bit?

Diamut Thin-Wall CNC Core Bits are engineered to deliver fast, efficient hole drilling in granite, marble, Dekton, engineered stone, and other natural stone materials. The thin-wall design reduces cutting resistance, allowing fabricators to drill clean, accurate holes while increasing productivity on CNC machining centers.

Designed for both hard and soft stone, these premium core bits feature integrated side cooling holes that quickly evacuate slurry and water from the cutting area. This improves cooling efficiency, reduces heat buildup, and helps extend tool life during demanding production work.

With a standard ½" Gas thread and available diameters ranging from 1" to 3", Diamut Thin-Wall CNC Core Bits provide outstanding versatility for countertop fabrication and CNC machining applications.

Why Choose Diamut Thin-Wall CNC Core Bits?

The thin-wall construction reduces the amount of material removed during drilling, allowing the bit to cut faster while placing less strain on the CNC machine. This results in shorter cycle times, cleaner holes, and improved production efficiency.

The strategically positioned side cooling holes continuously remove slurry while allowing fresh coolant to reach the cutting edge. This helps maintain lower operating temperatures, improves drilling performance, and significantly extends tool life during high-volume fabrication.

Whether you're drilling faucet holes in granite, machining quartz countertops, or fabricating Dekton slabs, Diamut Thin-Wall CNC Core Bits provide the speed, precision, and durability professional fabrication shops demand.

BB Industries carries Diamut CNC tooling, finger bits, core bits, bridge saw blades, polishing systems, and fabrication supplies trusted by professional stone fabricators throughout North America.
