I have recently been undertaking a lot of experiments with the relatively new product called Abranet, made by a Finnish company called Mirka. I have been using their cloth and paper backed disks for many years, with excellent results and feel very confident with the company for quality and reliability. However, after being given some of the Abranet product to trial – I am replacing all my paper and cloth backed disks with this new product.
The Abranet comes in grades P 80, P 100, P 120, P 150, P 180, P 240, P 320, P 360, P 400, P 500, P 600, P 800, P 1000 the material used is Aluminum oxide, bonded with resin to a Polyamide fabric backing. It is available in 6”, 5” and 3” disks as standard, also available in rolls and sheets for hand and other machine sanding.
I have found that this product, when sanding white oak, with a random orbit sander last 3 – 4 times longer than conventional cloth or paper backed disks. When sanding items that have been finished with paint or oils, that the Abranet disk does not become “clogged up” and if a residue does build up, then simply removing the disk, giving it a quick shake will dislodge about 99% of any material.
Dust, yes it crates a lot of dust, because it is so efficient at sanding, but I have found that my AEG, 8 hole ROS will pick up far more sanding debris, than it would with a conventional disk (and it was extremely good before). If I add a vacuum to the extraction port, then I get virtually 0 dust.
Heat, Non really, because it is so open-mesh, most of any heat is diffused by the surrounding air. Try it on the lathe for sanding a spindle or a bowl, whereas with conventional sanding disks or sand paper, you will feel the heat pretty quickly, almost to the point of burning fingers, the Abranet is definitely “cool running” all the time.
Aggressive sanding, you get a lot of stock removal quite quickly, even with the P 120, but you also get a very clean, even sanded surface when you finish, without unsightly scratches.
Interface Pad (picture 2). This pad is an optional extra (I recommend using it), but it is designed to be placed on your existing Hook & Loop pad and has 2 effects 1 – you add and remove the disks from the pad, not the ROS, therefore saving wear and tear on your ROS Hook & loop (these ROS Hook and loop are expensive to replace) and 2, the interface pad comes in 2 thicknesses, 3 mm and 10 mm, the 3 mm is designed for normal flat surface sanding, but the 10 mm is for contour sanding. The price of the 3 mm interface pad is about $6.00 each and come in packs of 5.
The price of the Abranet will vary on your distributor, but I would think about $1 to $1.50 per 5” disk. if like me you buy boxes of 50, then price comes spiraling down – do not forget they last a longer and give a better finish, so worth the extra cost – I will almost guarantee once you have tried one disk, you will not look back in anger.
If I could give this product more than 5 stars I would – it is tremendous
