I'm looking for a sander that will sand 90 degree corners. I normally do it by hand with 220 paper. It gets old real fast. Does anyone know if the Festool Linear sander that tool?
to The FOG Penny Geez,
It is unclear to me what you wish to accomplish. Are you trying to preserve the appearance of crisp edges? Or do you want just enough of a radius that the edges are less likely to cause injury?
I own a large custom cabinet shop, so routinely we make cabinet doors and drawer fronts. Hardly ever these days do our clients want us to run a slight radius with a round-over bit. From a distance they want well-defined edges, yet they also do not want to risk a skinned knuckle if a hand bumps those edges.
If those doors and drawer fronts involve frames, we sand those using RO 90 DX with the hard pads. The last step of the sanding process is to make a very light pass with the hard pad held at 45 degrees to slightly break the edge. My experience is when using a softer pad on the sander the slight break will not be as consistent, of in places it will be obvious.
By the way, my business is exclusively wholesale. Virtually all of my clients (designers and installers) already have business relationships with finishers. We always ask how fine they want us to sand. Most of our clients do not want us to remove 'mill glaze' from veneer, because they prefer to do so at the last possible moment prior to apply finish. Also, on solid wood, such as hardwood edge banding and door/drawer front frames, most clients do not want us sanding finer than 120 grit, because that is the point when they prefer to apply stain.
Of course we stock abrasives as fine as 600 grit, but rarely are asked to use that.
