Round head cylinder-shaped Diamond Sintered Burrs with a 2.35mm (3/32") shank. Sometimes referred to as Diamond Sintered Carving Points, these are perfect for engraving, carving and sculpting in glass, stone, ceramics and hardwood, plus grinding work in lapidary and jewellery.

Use the ball-nose top of the burr to make concave cuts and hollow out areas, and use the sides to cut flat areas and round edges.

Because the diamonds are sintered, these burrs are extremely durable. Maintain their efficiency by occasionally cleaning them with a dressing stone or aluminium oxide stick. Use with water, let the drill do the work, and apply very little pressure.

For use with all rotary drills and hand-held hobby drills such as a Dremel, pendant drills, micro motors and drill presses.

“The sintered diamond bur is superb. I have used it several times for filling and grooving out a larger area. Very nice indeed!” – Lesley Pyke
