This industrial-grade Sintered Diamond Finger Bit is a high-performance tool designed for heavy-duty material removal, shaping, and calibrating in professional stone fabrication environments. Proudly Made in the USA, this bit features a rugged metal bond matrix and a spiral flute design, built for maximum longevity and speed.
This bit is engineered for high-speed cutting and shaping of the hardest surfaces in the industry. It is ideal for:
Granite: Excellent for all grades of natural granite.
Quartz & Engineered Stone: Specifically designed to handle the abrasive nature of resin-based quartz.
Hard Marble: Provides stable, aggressive cutting for denser marble varieties.
Quartzite: Durable enough to tackle the extremely high silica content in quartzite slabs.
The 1/2" Gas Male connection is the global standard for CNC stone fabrication machinery. This bit is fully compatible with:
CNC Stone Routers: Including industry leaders like Bavelloni, Intermac, Park Industries, CMS, and Northwood.
Radial Arm Polishers: When equipped with a 1/2" gas adapter.
Stationary Grinding/Profiling Machines: Specifically those featuring an internal water-feed spindle.
Origin: Made in the USA
Bond Type: Sintered Metal Bond (Diamonds impregnated throughout the segment)
Grit Size: 35/40 (Aggressive / Fast Cutting)
Connection: 1/2" Gas Male Fitting
Outside Diameter (OD): 1.07" (~27mm)
Shank Diameter: 16mm
Shank Length: 110mm
Total Length: 8.25"
Cooling: Integrated Water Holes (Center-fed) for superior slurry removal and cooling.
Internal Water Feed: Designed for wet-use CNC spindles to ensure maximum tool life and prevent stone cracking.
Spiral Flute Design: Reduces vibration and allows for smoother, more stable cutting at higher feed rates.
Extreme Durability: Because it is sintered, this bit maintains its cutting effectiveness throughout its entire lifespan—it won't "strip" like electroplated or brazed alternatives.
Applications: Perfect for sink cut-outs, heavy-duty edge calibration, and internal profiling of 2cm and 3cm slabs.
