Our 11V9 Taper Cup Diamond & CBN Grinding Wheels are precision-engineered abrasive tools designed for sharpening, grinding, and reconditioning drill bits and other cutting tools. Featuring a tapered cup shape (11V9 specification), these wheels provide optimal access to drill bit flutes, relief angles, and cutting edges. Manufactured with high-quality diamond or CBN (Cubic Boron Nitride) abrasives in a robust vitrified or metal bond, they deliver exceptional durability, precision, and efficiency. Ideal for tool manufacturers, metalworking shops, and industrial maintenance facilities, these wheels ensure extended tool life and consistent performance.
Specialized Tapered Cup Design (11V9)
22.5° or 45° tapered sides enable precise grinding of drill bit relief angles and flute geometries.
Recessed center allows easy access to complex tool contours without interference.
Premium Abrasive Options
Diamond Wheels: Ideal for carbide-tipped drill bits, ceramics, and non-ferrous materials.
CBN Wheels: Optimized for HSS (high-speed steel), cobalt, and ferrous alloy drill bits.
High-Performance Bond Systems
Vitrified Bond: Provides porosity for cooler grinding and self-sharpening properties.
Metal Bond: Offers extreme durability for aggressive stock removal and long service life.
Precision and Efficiency
Achieves sharp, burr-free edges with surface finishes up to Ra ≤ 0.2 µm.
Uniform abrasive distribution ensures consistent results and minimal vibration.
Customization Flexibility
Available in grit sizes (#120-#1200), diameters (75-200 mm), and taper angles.
OEM/ODM support for tailored specifications, including bore sizes and bond hardness.

| Applications | Drill bit sharpening, tool regrinding, deburring, and surface finishing |
Drill Bit Sharpening:
Precision grinding of HSS, cobalt, and carbide drill bits (e.g., twist drills, step drills).
Tool Regrinding:
Restoring worn or damaged cutting tools, including end mills and reamers.
Deburring and Edge Preparation:
Removing burrs from machined components and refining cutting edges.
Industrial Maintenance:
On-site tool maintenance for manufacturing, aerospace, and automotive industries.
Machine Compatibility
Designed for tool and cutter grinders, universal grinding machines, and CNC grinding systems.
Ensure the machine spindle speed matches the wheel's maximum RPM rating.
Coolant and Lubrication
Wet grinding is recommended for heat-sensitive materials (e.g., HSS) to prevent tempering.
Use water-soluble coolants or grinding oils to extend wheel life and improve surface finish.
Grinding Parameters
Wheel Speed: 20-35 m/s.
Feed Rate: 5-30 µm/pass for fine finishing; 50-150 µm/pass for stock removal.
Light pressure to avoid overheating and premature wheel wear.
Dressing and Maintenance
Dress periodically with diamond dressers to maintain the tapered profile and sharpness.
Store wheels in a dry, clean environment to prevent bond contamination.
Factory-Direct Quality: Competitive pricing with strict quality control (ISO 9001 certified).
Proven Performance: Optimized for drill bit grinding with minimal heat generation and wheel wear.
Custom Solutions: Tailored designs for specific applications, including exotic materials.
Global Shipping: Fast delivery to manufacturing hubs in North America, Europe, and Asia.
Samples: Available for testing ($25-$100/wheel based on specifications).
MOQ: 10 pieces for standard sizes; custom orders require higher MOQs.
Lead Time: 10-20 days for production; expedited shipping available.
Certification: Complies with ISO 9001 and industrial safety standards.
