Why choose this product

Precision Diamond Grit for Superior Finish

HARFINGTON diamond grinding bits utilize a 120-140 grit diamond coating for efficient material removal and a smooth finish on hard surfaces. Unlike generic bits that may shed abrasive particles, these are engineered for consistent performance. The stainless steel construction ensures heat resistance and durability, crucial for prolonged use in India's varied workshop conditions. All customs duties and GST are pre-paid, offering a transparent landed price.

Ideal for Detailed Craftwork & DIY

These bits are perfect for gemstone carving, molding repair, cleaning castings, rust removal, and general polishing. They are also suitable for nail art, shaping natural or artificial nails. While they excel on hard materials, avoid using them on extremely soft plastics where they might melt. For very large-scale concrete grinding, consider specialized industrial equipment.

How to use

  • Select the appropriate bit — Choose the HARFINGTON diamond grinding bit best suited for your material (ceramic, glass, metal, stone, nails) and task (grinding, polishing, engraving, cutting).
  • Secure the bit in your rotary tool — Insert the 2.35mm shank into the collet of your compatible rotary tool, electronic grinder, or engraving machine. Ensure it is securely fastened and centered.
  • Operate at recommended speed — Set your tool's speed between 30,000-50,000 RPM. Wear safety glasses and keep the workpiece stable to avoid vibration and ensure effective, safe grinding.
  • Perform grinding and polishing — Apply steady, controlled pressure to the workpiece. Move the bit smoothly to achieve the desired shape, finish, or engraving. Store bits in the provided case after use.

FAQ, See What Others Asked

How to choose the right HARFINGTON diamond grinding bit?
Select bits based on material and task. For harder metals and smoother finishes, double-cut bits are often preferred. For softer materials and rapid removal, single-cut bits work well. HARFINGTON's 120-140 grit cylinder bits are versatile for general grinding, polishing, and engraving on ceramic, glass, stone, and metal.
What is the best operating speed for HARFINGTON diamond grinding bits?
For optimal performance and to prevent damage, maintain an operating speed between 30,000 to 50,000 RPM. Exceeding the maximum speed can lead to the bit jumping, reduced grinding effectiveness, or even bending of the shank.
Can HARFINGTON diamond grinding bits be used on standard household drills?
While the 2.35mm shank may fit a standard drill chuck, household drills typically operate at much lower speeds (500-2,500 RPM) than the recommended 30,000-50,000 RPM for these bits. Using them at low speeds results in poor finish and potential damage to the bit and workpiece.
How to ensure the longevity of HARFINGTON diamond grinding bits?
Use the bits at the recommended RPM range, apply steady pressure without excessive force, and keep the workpiece stable. Store them in the provided sturdy plastic box to protect the diamond coating and prevent damage during transport or storage.
Are HARFINGTON diamond grinding bits suitable for use in India?
Yes, HARFINGTON diamond grinding bits are imported for use in India. All customs duties and GST are included in the price, and they are shipped via ExpressBox with tracking. Ensure your rotary tool or grinder can achieve the recommended operating speeds for best results.
What materials can HARFINGTON diamond grinding bits work on?
These bits are effective on a wide range of hard materials including ceramic, glass, marble, stone, agate, tiles, and hard metals like iron and silver. They are also suitable for plastics, wood, and for nail art applications.
How to buy original HARFINGTON diamond grinding bits in India?
Purchase HARFINGTON diamond grinding bits from authorized US retailers and authorized brand partners exclusively through crowcrowcrow.com. Products are factory-sealed, imported per-order, and all duties and GST are included, shipped via ExpressBox tracked delivery.
