Sharpening Supplies Now Offers Atoma Diamond Plates

A New Approach to Diamond Plates

Whether you need them for sharpening or for flattening other stones, Atoma Diamond Plates have features that set them apart from other diamond sharpening stones.

Precision Placed Diamond Clusters
Instead of randomly coating the plate with diamonds, Atoma Plates have precisely placed clusters of monocrystalline diamonds laid out in a pattern on the surface of a stainless steel sheet. This arrangement creates a even, fast cutting surface more aggressive than randomly placed diamonds. And the geometric patterning creates channels between the clusters for waste material to collect, allowing it to get out of the way so the stone continues to cut without clogging.

Replaceable Abrasive Sheets

The diamonds are mounted to a 1mm thick sheet of stainless steel. This diamond covered sheet of steel is then mounted to a 10mm (3/8") thick piece of precision flattened aluminum. The resulting plate is reliably flat, sturdy and relatively light. And while the Atoma Plates last quite well, the diamond coated sheets are replaceable. Atoma Diamond Sheets Only are available in all four grits.

Practical Diamond Stones

Atoma Diamond Plates are Conveniently Sized

210mm (8-1/4") long x 75mm (2-13/16") wide, the Atoma Diamond plates are a great size, with plenty of surface area for use as sharpening stones or as lapping plates for flattening other stones.

Available in 4 grits

Depending on your need, you can opt for any or all of four grits:

  • 140 - for aggressive material removal reshaping edges or flattening stones
  • 400 - fast removal, but leaves a smoother surface
  • 600 - refines edges, smooths stone surfaces
  • 1200 - for fine edges or the smoothest stone surfaces

I recently placed my first order after finding you on the web while looking for grinding wheels. I am a customer for life. Here's why. My first order was a simple white grinding wheel for a "normal joe's shop". When I received the wrong wheel (150 grit instead of the ordered 100 grit) I called and without hesitation or the 3rd degree another wheel was sent off. No questioning of my integrity, intelligence or honor. Simply "I am sorry, we'll send the correct wheel off immediately..." The right thing was done by a neat guy. I was treated like an adult. Unbelievable in this day and age...proper...and priceless. Price, performance, responsiveness and customer service par excel-lance. 6-Stars! All my sharpening orders, albeit small shop orders, will now be with you. Promote you I will.
