These very coarse, Ball shaped Diamond Sintered Grinding Burrs are often called Diamond Sintered Carving Points. They are perfect for carving and shaping into stone, ceramics, granite, tiles, marble, glass and hardwood. Due to the diamonds being sintered, they are extremely durable. (Not suitable for delicate cold working of glass such as engraving)

• Available in either 8mm, 10mm, 12mm, 15mm, 18mm or 20mm diameters
• 6mm diameter shank (1/4")
• 46 grit (very coarse)

For use in rotary drills, flexible shafts, and die grinders.

Use wet, at a slow speed and dress with an aluminium oxide stick before use and after each use to reveal the fresh layer of diamonds. This will ensure you achieve the maximum life span from your sintered burrs.
