Description

The Atoma Advanced Diamond Sharpening Plate #400 Grit is a versatile tool designed to flatten dished whetstones and replace traditional whetstones up to 500 grit. It offers the perfect balance between coarse and fine grit, making it suitable for a wide range of sharpening tasks.

Compared to traditional whetstones, the main advantage of using an Atoma plate is its ability to remain flat over time, providing consistent performance and longevity. The Atoma #400 is a staple grit for general whetstone flattening, covering a range from low grits to high polishing grits.

To use the plate, mount your whetstone in a stone holder and rub the Atoma plate on top of the whetstone in various directions until the stone is effectively lapped.

Atoma Diamond Sharpening Plates are products of Tsuboman, a highly regarded Japanese manufacturer known for their refined diamond products. These plates are made of mono-crystalline diamonds with a cutting abrasive surface mounted on a 10mm thick stainless steel base. The base is machined to be extremely flat, ensuring the diamond plate remains flat throughout its use.

The quality and durability of Atoma plates are among the highest available on the market. They feature precision-made surfaces with high uniformity, maintaining their flatness even after prolonged sharpening sessions. The diamond plate can be replaced after a few years without purchasing another baseplate, as they are adhered using strong double-sided tape.

Atoma Diamond plates can be used dry or with water, depending on personal preference.

Best choice! Absolutely necessary for anything above basic stock bass.
Bonded to services well, completely removed panel reverberation in my tacoma. Also really made the doors so much quieter even when closing. Very happy with the result. Used only one set on my 01 tacoma 4 door. Installed inside doors on exterior skin panel, over interior door panel access holes (sealing the door to provide backpressure to door speakers (left drains open)), roof panel, and back wall of cab. Achieved about 70% coverage and am very happy. 2 8in SKAR SVR8 at 1oh on walmart power acustic 2500 (only rated to ~800rms at 2oh, forum showed testing at 1oh worked about 1kw) in 6th order with blow through into cab. With cab gain, im over 130db between ~30 and ~50hz. This was a necessary addition!

Looks good so far, will update once installed
Have not installed this yet, so this is only a first impression review. I bought it to use in the wheel well area on my truck, so I’ll update later once I actually get it on and see if it makes a real difference. So far it looks good out of the box and seems straightforward enough. One thing I’d recommend is making sure you have a sound deadening roller for install, because I would not try putting this on without one. Too early for me to say how well it works for road noise since it is not installed yet, but I wanted to post my initial thoughts for now and will update later.

Great product, very impressed
Looks good, adhesive grabs well, forms well to floor pans. Price is great will be ordering more again. It definitely deadened the tin can sound you can get.
