Bihui 2mm - 38mm Diamond Conical Milling and Beveling Bit

The Bihui Diamond Conical Milling Bit is a professional-grade, high-precision rotary detailing tool engineered for enlarging, reshaping, and smoothing pre-drilled holes in dense architectural substrates. Featuring a tapered cone design coated in premium industrial diamonds, this heavy-duty bit is highly recommended for tilers, stone fabricators, and plumbing installers. It allows operators to effortlessly expand circular openings from a tiny pilot hole up to a wide clearance, providing clean results when fitting pipework, shower valves, and electrical conduits.

Why Choose the Bihui Conical Diamond Milling Bit?

• Highly Versatile Taper: The gradual conical geometry allows a single bit to process an expansive range of hole diameters. Whether you need to lightly clean up a small screw hole, adjust a misaligned pipe opening, or enlarge a circular cut out to clear large mechanical fittings, this versatile tool adapts instantly.

• Stress-Relieving Bevels and Smooth Edges: Raw, straight-drilled edges in hard materials harbor high mechanical tension and micro-fractures. Utilizing this conical bit to apply a smooth, uniform bevel (chamfer) relieves this surface stress, drastically reducing the risk of large-format tiles or stone slabs cracking over time.

• Premium Medium-Grit Diamond Matrix: Engineered with an optimized medium-grit configuration of industrial diamonds. This specific density delivers an aggressive material removal rate for rapid shaping, while leaving behind an exceptionally clean, chip-free edge that preserves delicate surface glazes.

• Vacuum-Brazed Structural Longevity: Manufactured using advanced vacuum-brazing technology, which molecularly bonds the premium diamond grit directly to the high-tensile steel core. This ensures maximum heat resistance and structural integrity, allowing for long-lasting performance during high-RPM dry milling operations.

• Direct-Fit M14 Threaded Connection: Outfitted with an industry-standard internal M14 thread that spins directly onto the spindle of a standard high-speed angle grinder. This direct mechanical mounting provides zero-wobble concentricity and ultimate control while working freehand.

• Broad Material Application: An essential detailing and correction tool for premium modern fits, this robust bit works smoothly across:

  • Dense porcelain floor tiles and ultra-thin large format slabs

  • Engineered quartz, sintered stone, and luxury granite countertops

  • Polished marble, limestone, slate, and architectural ceramics
