Description

Sphere rotary burr for wood carving

Hollow a bowl in an afternoon, not a week.

The Gear Elevation sphere rotary burr is a golf-ball-size carving ball covered in sharp rasp teeth on a sturdy 10 mm (3/8 in) shank. Chuck it into your angle grinder or drill and it becomes a power carver for bowls, spoons, kuksas, sculptures and every curved surface in between.

Woodworkers call it a ball burr, a ball gouge, a carving ball or a rotary rasp. Whatever you call it, it does one job brilliantly: it removes wood fast and leaves a smooth, round hollow behind.

Precision carving

Deep, smooth curves with far less effort.

Scooping a bowl or a spoon by hand with gouges and mallets is slow, tiring work that leaves torn grain and rough edges. The sphere burr takes over the heavy lifting: guide it across the wood and it shaves away material in even, controlled passes.

Because the ball is round, it cuts the same in every direction. Sweep it side to side for a wide, shallow dish or rock it in place for a deep, tight hollow. Your shapes come out flowing and even, ready for a quick sanding.

Why carvers reach for it

Three reasons it earns a spot on your bench.

Fast

Hogs out wood quickly

Coarse rasp teeth remove material fast, so hollowing work that once took days goes in a single session.

Smooth

Clean, round finish

Teeth all around the ball leave an even, consistent surface with sharp, polished cutting edges.

Tough

Made to last

Premium carbon steel holds its edge on oak, maple and other hardwoods, project after project.

How it cuts

Hundreds of sharp teeth, all working at once.

Rows of pyramid-shaped rasp teeth wrap the entire sphere. Each one takes a small, clean bite, so together they cut quickly while keeping the surface smooth. The fine polishing on the cutting edges keeps them sharp for crisp, meticulous results.

The stepped shank keeps the ball rigid and centered at speed, so the burr runs true and stays under your control through long carving sessions.

What woodworkers say

Rated highly by the carvers who use it.

"I was looking for a tool to remove wood in a concave shape. This is perfect. It fits in my 4" side grinder."

Peter W., verified review

"Used to make small spoons. Worked very well on curly maple, blood wood and other types of wood. Very pleased with it!"

Harold B., verified review

"There's no sign of wear after a few hours of sculpting white oak. It's perfect for sculpting curved areas."

Timothy L., verified review

Carvers use it for wooden bowls, fruit and salad bowls, spoons and sculptures, and they keep coming back to the same words: smooth, durable and a nice quality burr at a reasonable price.

One burr, many jobs

From spoons to cylinder head ports.

The sphere burr is at home in the wood shop and well beyond it. Use it for bowls, spoons, kuksas, chair seats, sculptures and relief carving, and for chamfering, deburring and engraving on wood, plastics and light alloys.

Professionals and hobbyists use the same shape for model engineering, casting cleanup, weld blending, jewelry making and porting work. If it needs a smooth, rounded hollow, this is the tool for it.

Two finishes

Black or Silver, the same fast cut.

Choose a deep black finish or a bright silver finish in the Color menu above. Both carry the same ball, the same rasp teeth and the same 10 mm (3/8 in) shank. Many carvers keep one of each on the bench.

Guide it

Hold the tool with both hands and let the ball do the cutting with light, sweeping passes.

Shape and finish

Work from rough to fine, then give the smooth hollow a quick sanding.
