Arbortech Ball Gouge: Fast, precise hollowing for spoon and small-bowl carving

In a typical UK kitchen, space is at a premium and small tools need to earn their place. Arbortech Ball Gouge fits onto a standard angle grinder and converts it into a rapid hollowing tool for spoons and small bowls, saving time at the bench. Is it the right addition to a hobby carver's kit?

⚡ At a Glance

• Cutting Quality: Smooth, rapid hollowing of small concave surfaces using a 30 mm spherical cutter for consistent finishes
• The go-to for: Spoon-makers and small-bowl carvers who need quick, repeatable concave cuts
• Trade-offs for: Furniture makers shaping deep chair seats; the 30 mm diameter limits material removed per pass, forcing many passes and extended grinder runtime to reach deep hollows

A 30 mm ball-shaped gouge attachment that fits most 100 mm and 115 mm angle grinders. The rotatable, self-sharpening ring blade combined with Anti-Grab Technology targets fast, low-dig hollowing on small to medium carving projects.

Rapid Hollowing – 30 mm Spherical Cutter

Operating at up to 12,000 RPM, the 30 mm spherical cutter removes material quickly from small concave areas, matching profiles used for spoons and small bowls. In-workshop use shows that the compact ball shape lets the grinder follow curves with minimal bouncing or chatter.

Carving sessions finish faster with fewer finishing passes, making batch work such as sets of spoons far quicker to complete. The small diameter suits detail work and repeatable concave shaping for hobby and small-scale sculpting.

The Ring-Shaped Blade Advantage in Detail

A ring-shaped cutter that is self-sharpening, rotatable and replaceable keeps the cutting edge consistent through longer sessions, while Anti-Grab Technology reduces the tendency to dig into timber. Compatibility with common 100 mm and 115 mm grinders keeps setup straightforward on widely used machines.

Edge rotation and replacement cut down workshop downtime compared with single-piece cutters, so carving remains productive over multiple uses. Supplied accessories let users rotate or change the ring quickly between projects.

❓ Frequently Asked Questions

Q: Which angle grinders will accept the ball gouge?

A: Fits most standard 100 mm (4") and 115 mm (4 1/2") angle grinders; confirm flange compatibility before mounting. Pro-tip: remove the existing disc and follow the grinder maker's fitting instructions, checking guard clearance and secure fastening with the included Allen key.

Q: What is included in the box and how quickly is it ready to use?

A: An Allen key and the milling ball are supplied so the cutter can be mounted and adjusted straightaway. Pro-tip: keep the Allen key with your kit and rotate the ring periodically rather than waiting until the edge dulls, which reduces session interruptions.
