Atoma Diamond Sheet - #1200

These Atoma Diamond Sheets are identical to the abrasive surfaces used in our Atoma diamond plates—offering the same fast, hard-wearing cutting performance—only without the fixed aluminium substrate.

Supplied with a waterproof adhesive backing, these sheets can be applied to the flat substrate of your choice, making them ideal for those replacing a worn sheet or building a custom sharpening setup.

To make things easier, we've sourced two substrates that pair beautifully with the diamond sheets:

1. Glass Substrate

Chosen for its consistent flatness, our 10mm glass backing turns your diamond sheet into a lightweight, low-profile flattening plate with minimal variation. Especially well-suited for flattening waterstones, the glass option can be double-sided, allowing you to mount different grits on each face. Once adhered, it performs like a full diamond plate with excellent accuracy.

2. Steel Substrate

This heavy 16mm mild steel plate was developed in response to customer requests for a flat, weighty base suitable for serious grinding. Machined to within 0.005mm flatness, it’s ideal for metalworking applications and sharpening workflows that require more heft. Designed to be clamped in a vice or used benchtop with waterstones passed over the surface, it can also host two different grits—one on each side—or double as a traditional lapping plate.

Please note: Each item is sold individually. To build a complete setup, please add your preferred diamond sheet and substrate (glass or steel) to your cart separately. We’ll ship them individually, and you’ll need to adhere the sheet to your chosen base at home.
