![]() ![]() The aluminum oxide abrasive showed a good level of longevity with the ability to completely sand both sides of approximately 62 square feet of Baltic Birch plywood using a single disc without signs of degradation in cut quality. The Whiteline discs showed mild shedding when rolling over sharp corners or "edge banging" using the orbital sander. During light hand sanding with a sanding block to break edges, the abrasive grain resisted shedding. The sanding discs show good resistance to tearing in flat panel applications using a random orbital sander. The Whiteline offers a D-weight paper backing at P120 and below and C-weight paper backing at P150 and greater. The Rhynogrip Whiteline is a budget friendly line that will accomplish most medium to fine woodworking tasks. ![]() However, based on my experience with Festool Rubin at $36 per box fifty (50), I’d have to use two Rhynogrips White discs to equal one Festool Rubin. Obviously, I’m not testing this along side other competitive lines. Given a working time of 1-hour per disc, you can expect to spend between $2.25 and $2.72, per 8-hour working day, per user during continuous sanding. Whereas P150 and greater are less aggressive and therefore are suitable to a lighter weight backing.Ī box of fifty (50) 5” Rhynogrip White Line 8+1 velour backing sanding discs will cost you between $14 ( ) and $17 ( ) depending on the distributor. It makes sense for the P120 and lower abrasives to be made of a heavier paper weight due to the heavier cutting demands of the lower grits. ![]() Paper backed products also generate less heat than cloth backed products however, they’re more prone to tearing and abrasive grain shedding. They offer a greater overall flatness than cloth backed products, but are less consistently flat than film backed products. They’re not as sturdy as cloth and film back products but are less expensive to manufacture. Paper backed abrasive products are ideal for light to medium sanding of flat surfaces. Grits between P36 and P120 come in a D-weight, while grits of P150 and finer come in a C-weight paper backing. Paper backed abrasives come in a variety of weights ranging from A through G, with A being the lightest and most flexible to G being the heaviest and most sturdy. I tested the P120 and P180 grits on a computer desk build made of 12mm Baltic Birch plywood. I was sent P120, P180, P220, and P320 grit varieties with a velour backing (hook and loop), and Festool hole pattern. The Rhynogrip White Line is Indasa’s economy line. In May of 2020, Indasa, an abrasives coatings company based out of Portugal, sent me samples of four of their product lines (Rhynogrip White, Red, Plus, and Ht Line) to test in my shop. ![]()
