Full details

The Makita D-18764 metal grinder disc is an essential consumable for metalworkers and contractors who require high-precision cuts in stainless steel, inox, and aluminum materials. These discs are ideal for professionals seeking clean finishes on pipes, extrusions, and welds, though users must be aware that the 1.2mm extra-thin kerf requires a steady hand and controlled pressure to prevent premature disc wear or breakage.

Extended Product Information

FAQs

Can I use these for grinding down welds?

No, these are strictly cutting discs. Using them for side-grinding can cause the disc to shatter.

What is the bore size of this disc?

The bore size is 22mm, which is standard for most 115mm angle grinders.

Are these safe for stainless steel?

Yes, they are specifically engineered for stainless steel and inox to ensure clean, contamination-free cuts.

How thick is the disc?

These discs feature an extra-thin 1.2mm kerf.

Does this pack include a mounting tool?

No, the pack includes 12 cutting discs only.

Troubleshooting

Disc is wearing down too quickly

Reduce downward pressure; let the speed of the grinder do the cutting to prolong disc life.

Disc is vibrating heavily during use

Ensure the disc is properly centered on the spindle and that the locking nut is fully tightened.

Excessive sparks or burnt edges

Check that the cutting speed is consistent and do not stall the grinder in the material.

Pros and Cons

Pros

  • Extremely thin kerf allows for fast, accurate cuts with less resistance
  • High-quality material prevents discoloration when cutting stainless steel
  • Convenient 12-pack size ensures you have replacements on hand
  • Excellent for precision tasks like notch cutting and pipe trimming

Cons

  • Extra-thin discs are more prone to shattering if subjected to side pressure
  • Not intended for grinding or beveling, only for straight-line cutting
  • Requires professional-grade angle grinders to ensure stable RPM speeds

Setup, Compatibility & Care

To use these discs, ensure your angle grinder has a 22mm bore mounting flange. Always ensure the disc is tightened securely but do not overtighten, as this can crack the disc. When installing, always check for any structural defects or chips in the disc before beginning your work. Store the discs in a dry, moisture-free environment; humidity can affect the bonding agent in abrasive wheels over time. When working, always wear appropriate PPE including eye protection and gloves. Avoid applying excessive downward pressure, as the disc is designed to let the high-speed rotation perform the work; forcing the tool can lead to premature wear or safety hazards.
