Our diamond blind hole core bits, also known as anchor drills, are high-precision drilling tools featuring CNC-machined steel bodies and specialized segmented diamond tips. They are engineered specifically for drilling precise blind holes (non-through holes) and undercut anchor holes in dense, hard materials. These core bits ensure absolute depth control, exact hole diameter, and smooth interior walls required for the secure installation of mechanical anchoring systems.
They are extensively utilized across stone fabrication, building facades, and heavy construction sectors:
Stone Facade Anchoring: Essential for drilling precise blind holes in granite, marble, and engineered stone panels for undercut anchor systems in exterior wall cladding.
Concrete & Masonry Anchoring: Ideal for setting heavy-duty drop-in anchors, expansion bolts, and chemical anchors in hard concrete structures.
Monument & Architectural Stone: Applied in high-value stone craftsmanship where precise, non-penetrating holes are required for hidden mounting hardware.
Tile & Porcelain Installation: Used for precise blind hole drilling in large-format porcelain slabs and ceramics without cracking the delicate surface.
Precise Depth & Diameter Control: The CNC-machined steel barrel and integrated depth-stop designs guarantee consistent hole depth and exact diameters, crucial for the pull-out strength of anchor bolts.
Premium Segmented Diamond Matrix: Formulated with high-grade industrial diamond grains and robust metal binders, providing rapid penetration speeds and clean, chip-free hole edges.
Heavy-Duty CNC Machined Core: Engineered with thick-wall alloy steel bodies precision turned on multi-axis CNC lathes to ensure absolute concentricity (+/-0.005 mm) and prevent drill wobble during operation.
Optimized Swarf Evacuation: Features specialized side slots and internal water feed compatibility to efficiently flush out stone dust, preventing bit jamming and extending tool life.
Versatile Shank & Custom Sizes: Fully customizable in drilling diameters (commonly 6mm to 35mm), drilling depths, and shank styles (straight round, hex, or threaded) to fit standard anchor drilling machines and CNC work centers.
Backed by over 10 years of intensive CNC machining experience, we are a professional all-around custom hardware manufacturing facility dedicated to delivering ultra-precision component processing services. We specialize in high-precision CNC component machining and contract manufacturing, acting as a reliable direct-source hardware supplier rather than an assembler of complete machinery equipment.
Direct Factory Price Advantage: Source your precision hardware components, core bit steel barrels, custom anchor drills, and mounting adapters directly from our production workshop to eliminate trading company markups.
All-Around Hardware Fabrication: We process a full spectrum of high-performance materials. Beyond standard metals, our extensive machining capabilities cover steel, aluminum, iron, brass, titanium alloys, and industrial plastics to meet your exact engineering specifications.
Bespoke Precision Processing: We provide highly specialized custom machining services tailored precisely to your CAD/3D STEP models, ensuring perfect OEM fitment for your specific diamond tool designs or architectural anchoring hardware.
Advanced Multi-Axis CNC Capabilities: Equipped with state-of-the-art CNC turning and milling centers, our technical team handles high-complexity geometry, ultra-fine surface finishes, and tight dimensional tolerances with exceptional proficiency.
Rigorous Quality Control: Every machined component undergoes severe dimensional audits, concentricity testing, and runout verification using advanced inspection equipment to guarantee premium out-of-the-box performance and safety.
