Solid Carbide Milling Disc
A solid carbide disc that mounts on the angle grinder you already own and cuts metal into clean chips you can sweep up. One disc outlasts 1,000 to 5,000 grinding discs, and the prep comes out metallic bright, ready to weld.

Why fabricators switch from grinding
Put an abrasive disc on aluminum and four things go wrong at once.
Plastic-bonded grit embeds in soft metal and causes porosity and inclusions when you re-weld.
Grinding throws it into the air. Milling makes chips you can sweep off the floor.
Abrasive discs drive the part past 300°C and distort it. Milling holds it at 40–60°C.
A flap disc lasts ~30 min on aggressive aluminum removal. A milling disc runs 300–500 hours before its first resharpening.
That last gap compounds. A disc that replaces thousands of consumables resets your cost per part.
The cutting action
No embedded abrasive, so the prep is clean and weld-ready with nothing to cause porosity.
Chips you can sweep off the floor, not the fine combustible dust grinding aluminum throws into the air.
The workpiece stays cool, so it doesn't distort and the base metal keeps its properties.
Side by side
| Dimension | Milling Disc | Grinding / Flap Disc |
|---|---|---|
| Removal rate | 40–70% faster than grinding | Slows as the disc wears and clogs |
| Surface quality | Metallic bright, no smearing | Smeared, embedded abrasives |
| Workpiece temperature | 40–60°C | 300°C+, distortion risk |
| Dust / particles | Chips only, no airborne dust | Fine combustible dust on aluminum |
| Tool life | 300–500 hrs per cycle, up to 4,000 hrs total | ~30 min per disc |
| Kickback risk | Virtually eliminated | Significant with hard stones |
| Weld contamination | Zero abrasive residue | Embeds particles, causes porosity |

A milling disc cutting aluminum weld prep on a standard angle grinder. Chips on the floor, a metallic-bright surface, and nothing in the air.
Choosing a disc
Cut on one face: beveling, chamfering, leveling welds, deburring, and surface scrubbing.
Cut on both faces with a defined radius. Open butt and fillet welds and cut V-preps in one pass.
Both functions in one disc. Bevel, scrub, and open seams without a tool change.

Industries & applications
Contaminant-free processing is a requirement. No embedded abrasives, no heat distortion, no structural changes to the part.
Battery enclosures, structural castings, and aluminum body panels need weld prep that won't compromise the base material.
Thick aluminum plate, long seams, enclosed hull spaces. Exactly where grinding dust becomes a serious hazard.
Made & supported
The discs are made in Germany to EN 847-1 and supplied through MIGAL.CO. Inmotion sells, supports, and handles resharpening in the US.
One disc replaces 1,000 to 5,000 grinding discs, Over its life it eliminates far more consumable spend than it costs. Fabricators report 39 to 78% lower consumable costs.
Resharpening handled for you, When a disc reaches the end of a cycle, send it to us. We coordinate resharpening through the manufacturer and return it ready for another 300–500 hours. Five to seven cycles per disc, up to 4,000 hours of total life, over two years on a single-shift line.

FAQ
Any standard electric or pneumatic angle grinder rated at a minimum of 1,500 W and 12,000+ rpm. No special equipment.
300 to 500 hours per cycle before resharpening, depending on the material. Each disc resharpens 5 to 7 times, for total life up to 4,000 hours.
Yes. Steel-specific discs use different tooth geometries and run slower, 1,800–3,200 rpm, versus 8,500–15,300 rpm for aluminum.
Single-sided discs cut on one face, for beveling, chamfering, and leveling welds. Double-sided discs cut on both faces, for opening butt and fillet welds. The Doubleworker combines both in one disc.
A single milling disc replaces 1,000 to 5,000 conventional grinding discs over its lifetime. Fabricators report 39 to 78% lower consumable costs.
