Aluminum Milling Disc

The TFT Pneumatic Milling Discs are best for grinding aluminum welds, bevelling, leveling of welds or general scrubbing jobs. You can also use them for root pass cleaning and opening butt or filet welds. These aluminum grinding discs are superior to traditional grinding discs because regular discs have pores and they get filled with the melted aluminum.

One-sided milling discs are used for bevelling, leveling of welds, or general scrubbing (e.g. root pass cleaning).

Double-sided milling discs are best for opening weld roots, butt welds or fillet welds.

Each milling disc is unique. We design and build them to work with specific materials. Whether aluminum or titanium, copper or stainless steel. They all part from the principle of milling, not grinding. That being said, we have milling discs available for the following materials.

    • Aluminum
    • Titanium
    • Copper
    • Brass
    • Carbon/Fiberglass
    • Plastics
    • Wood
    • Hastelloy


Discs are available in 3, 4 ½ and 5 inch diameters, according to the grinder to be used.

Use milling rings on standard angle grinders, electric or pneumatic, with minimum 13,000rpm and 1,500 watts.

Milling Discs Features

No explosion hazard from aluminum dust

Chips are produced instead of dust which means a significant contribution to work safety.

No Abrasive residues, no smearing

Especially with aluminum no plastic bonded abrasives may be used as they leave residues in the material that may cause weld defects like porosity or inclusions after rewelding. In using our milling disc weld defects are immediately visible and the smearing caused by grinding is avoided.

No stress in the material through overheating

With milling the workpiece remains cold. Overheating is avoided.

Higher process efficiency

Through higher material removal rate and elimination of frequent tool changes due to an estimated product lifetime of 300 hours in comparison to 30 minutes of a conventional flap disc.*

No sudden or unexpected reaction/kickbacks

Unlike traditional cutting discs, with our milling discs you will notice the kickbacks are drastically reduced and in most cases completely eliminated.

Long expected lifetime of disc

Each disc has a lifetime before resharpening of up to 500 hours and they can be resharpened up to 7 times, giving a total lifetime of 4,000 hours. This means non-stop grinding for 8 hours shifts, 52 weeks a year, for 2 years.

Cost reduction/Savings

Our discs, including the initial cost and 7 resharpenings, allow for cost savings of as little as 39% and as high as 78% when compared to a similar product commonly referred to as “ninja blade.”

TFT-PNEUMATIC does not assume or imply any lifetime guarantees as many factors influence and affect this determination including but not limited to: User proficiency, user vices, air pressure, tool being used as well as material being removed.
