Precision Crafting for Hard Materials

About this item

Luo ke 20-piece diamond burr bits feature a 1/8" shank and 1.5mm needle shape, crafted from premium diamond particles and alloy. These bits are designed for precise drilling and expanding holes in hard materials like stone, glass, ceramics, and jewelry. For optimal performance and longevity, use with a lubricant and ensure proper tool cooling to prevent overheating and premature wear. Compatible with most rotary tools, drills, and grinders.

Proper installation and operation are key to maximizing the lifespan of these diamond burrs. Always ensure the tool is securely fitted and runs smoothly without excessive vibration. Overheating can cause the diamond coating to graphitize, significantly reducing its effectiveness. Regular use of coolant, such as water, is highly recommended, especially for dry drilling applications. Avoid shaking the tool during operation to prevent localized damage and premature wear.

These Luo ke diamond burrs offer a cost-effective solution for detailed crafting and fabrication in India. Imported directly, all customs duties and GST are included in the price. Your order is shipped via ExpressBox with tracking, ensuring reliable delivery to your pincode within 12-14 days.

Why choose this product

Engineered for Precision in Hard Materials

These Luo ke diamond burrs are specifically engineered for precision work on challenging materials. The premium diamond particles ensure effective grinding and shaping, while the alloy base provides durability. Unlike generic burrs, the 1.5mm needle shape allows for intricate detailing and precise hole expansion crucial for jewelry and fine craft applications. Imported from authorized US retailers, these bits are factory-sealed and sourced for authenticity, ensuring consistent performance that local alternatives may not match.

Who Should Use These Burrs & Who Should Consider Alternatives

Ideal for jewelers, craft enthusiasts, and DIYers working with stone, glass, ceramics, and hard metals. If you require large-scale material removal or are working with very soft metals like aluminum or brass, consider burrs with a single-cut or coarser double-cut pattern. For extremely high-volume industrial cutting, specialized industrial-grade burrs might be more suitable. Always use with appropriate cooling and speed settings for optimal results and tool life.

How to use

  • Secure the Burr — Insert the 1/8" shank of the Luo ke diamond burr bit into the collet of your high-speed rotary tool or grinder. Ensure it is securely tightened to prevent wobbling during operation.
  • Apply Lubricant & Set Speed — Apply a lubricant, such as water, to the work area and the burr bit. Set your rotary tool to a high speed, ideally between 15,000 and 30,000 RPM, for optimal cutting performance and to prevent overheating.
  • Begin Cutting — Gently bring the spinning burr into contact with the material (stone, glass, ceramic). Use light pressure and a smooth, controlled motion. Avoid excessive force or shaking the tool to prevent damage to the bit and workpiece.
  • Clean and Store — After use, clean the burr bit to remove debris. Store the bits in their case or a dedicated holder to protect the diamond coating and prevent corrosion, especially in humid Indian climates.

FAQ, See What Others Asked

How to buy original Luo ke diamond burr bits in India?
Purchase original Luo ke diamond burr bits directly from crowcrowcrow.com. We source exclusively from authorized US retailers and authorized brand partners, ensuring factory-sealed products. All customs duties and GST are pre-paid and included in the listed INR price. Your order is shipped via ExpressBox with tracking, arriving within 12-14 days.
What is the primary functional difference between single-cut and double-cut carbide burrs?
Single-cut burrs have a continuous right-hand spiral flute designed for rapid stock removal and long chip clearance on non-ferrous materials, soft steels, and plastics. Double-cut burrs incorporate a secondary set of flutes cutting in the opposite direction, which breaks shavings into small granular chips, lowers operator vibration, improves tool control, and leaves a cleaner finish on harder alloys.
Can these rotary cutting burrs be operated using a standard household power drill?
While standard power drill chucks can physically hold the burr shank, drill operating speeds (typically 500 to 2,500 RPM) are significantly below the optimal operating range of 15,000 to 30,000 RPM required for carbide cutting burrs. Operating at inadequate speeds leads to severe vibration, rough surface finishes, and potential chipping of the cutting teeth; high-speed die grinders or dedicated rotary tools provide the intended performance.
Are Luo ke diamond burr bits safe for use?
Yes, Luo ke diamond burr bits are designed for safe operation when used correctly with appropriate tools and safety precautions. Always wear safety glasses and use a lubricant for cooling. Ensure your rotary tool or grinder is operating at the recommended high speeds (15,000-30,000 RPM) to prevent tool damage and ensure smooth, controlled cutting.
How to use Luo ke diamond burr bits for best results?
For best results, use Luo ke diamond burr bits with a high-speed rotary tool (15,000-30,000 RPM) and a lubricant like water to keep the bit cool. Ensure the tool runs smoothly without vibration. Apply light pressure and avoid excessive force. Use a continuous drilling motion, and avoid shaking the tool to prevent localized damage and premature wear.
What is the best Luo ke diamond burr bit for stone and glass?
The Luo ke 1.5mm needle shape diamond burr bits are excellent for precise work on stone, glass, ceramics, and jewelry. Their diamond coating provides effective grinding on hard surfaces, and the needle shape allows for detailed shaping and hole expansion in these materials.
How long will these diamond burr bits last?
With proper use, including adequate cooling, lubrication, and avoiding excessive vibration or incorrect speeds, these diamond burr bits are designed for long-lasting use. Diamond-coated tools are durable, but performance depends on correct application and maintenance. Using them on materials they are designed for, like stone and glass, will maximize their lifespan.
