Stone+ Inverted Conical Burrs

Carving stone has historically been a job for a hammer and chisel. As artists have begun to embrace technology to streamline their work, the die grinder or power drills are becoming a popular option for carving stone, replacing the hammer and chisel in many cases.

Precisely carve, polish & hollow stone!

Stone+ Inverted Conical Burrs

These Inverted cone-shaped Diamond Sintered Burrs are perfect for engraving, carving and sculpting in glass, stone, ceramics, and hardwood, plus grinding work in Lapidary and jewelry.

Coated with Extra Durable Diamond Grains

Due to the diamonds being sintered they are extremely durable. Maintain their efficiency by occasionally cleaning the sintered burrs with a dressing stone or aluminum oxide stick, use with water, let the drill do the work and apply very little pressure.

High Speed & High Tensile Strength

The stone+ should be used at an electric grinder speed as high as 2800-6000 r/min. But you need to be sure to use a handpiece with no wobble. High speed will prevent clogging in flutes of your burrs.

Inverted Conical Grinding Head gives smooth precision

When you need a diamond tool to sculpt, grind, shape and carve your hard materials, these inverted cone-shaped diamond-coated burrs are ideal. They give smooth precision and are great for making V-cuts and grooves.
