Product Description

Amazon.com

A versatile all-in-one machine, this 4-inch belt sander lies horizontally for edge- and face-sanding without the runaway effort of a handheld belt sander, thanks to the sturdy, adjustable, and removable backstop. Or position the belt vertically (or at any angle between 0 and 90 degrees) for contour, bevel, and chamfer sanding--the tables on both sanders tilt to 45 degrees. Use the miter gauge, and you're able to sand in compound angles. The belt sands 2,000 surface feet per minute, and the disc rotates at 3,100 rpm for serious stock removal. A die-cast aluminum base offers stability at a remarkably spare 33 pounds. Predrilled base holes make mounting a simple task. Delta even provided a built-in 2-1/4-inch dust port for connection to a shop vacuum to keep your workshop air clean. Sure, handheld sanders have their place in a woodworker's shop, but add this to your collection and you won't know how you ever got along without it. --Kris Jensen-Van Heste

From the Manufacturer

Sand a variety of projects with this four-inch belt and six-inch disc sander. Powered by a 1/3-horsepower induction motor, this sander runs smoothly and has plenty of power for woodworking needs. The belt unit can be positioned horizontally for edge or face sanding or vertically for contour work or use with the tilting table. The tilting table installs in one of two positions for use with either the belt or disc units. The table tilts up to 45 degrees and has a slot for use with the miter gauge for angled work. A single dust port can be used for dust collection from either the disc or the belt and fits a standard 2-1/4-inch shop vacuum hose. Belt changes are simple with the tensioning lever and belt tracking control knob.

This is an excellent tool for anything short of production woodwork. One friend uses his in a full-time luthier's shop, making and repairing violins and other stringed instruments, and he's as happy with it as he's been with any tool.
I've only found one small sander I like better- a slightly more expensive Ryobi with a belt that tilts vertically. But other than that there's not much to choose from between the two. An excellent value, and of course Delta's warranty and service in first rate.

Easy to slow belt when sanding - aka low power. Motor burned up with 3 years of very infrequent light duty work - wooden bird houses and boxes. Motor began emmiting smoke with no load as soon as it was turned on with ambient temp of 40F. Delta Shopmaster products are thier low cost lines. I thought a simple Delta product for $90 would last longer.

It is an ok machine for the light use home shop. However it is under powered and under built for anything besides sanding the edge of a 1x3. I was sanding some paint off a 1x3 piece of pine, with 50 grit very corase paper. To much pressure and the machine would bog down. Careful as I was to keep the pressure light, let the motion and paper do the work, the drive belt fell apart. I decided to write the review while I was herelooking for a new belt (or perhaps a 6 pack). Note purchased at local hardware store, for a few dollar more then Amazon price.

to the point, this machine has a plastic drive wheel. I got a small piece of wood jerked out of my fingers (my fault) and it wedged the belt and stopped it (safety built in). However, that stripped the plastic drive wheel. After that, anything above slight pressure on the sanding piece and the belt/disc stopped. I didn't want to go through the hassle of begging Delta for an exchange, so I fixed it with JB Weld. Now it works fine. The discovery of the flimsy construction has kept me from considering Delta anything.

I recently purchased this product. I found the manual to be well thought out and easy to follow. Assembly was straight forward and easy. The unit seems to be fairly well constructed for its size and intended purpose. My only complaint is with the belt which has an overlap seam and can cause considerable thumping in some applications. I would definately reccommend this product for small projects. However, be sure to check everyone's price, as I found one seller to have a price considerably below everyone elses.

Purchased this sander and used it for light sanding only on small parts. Not many hours of use in two years when the warranty ran out. But so did the motor. It costs more for a motor than the whole sander so be aware that this is what I would consider a throw away tool.

This is definitely NOT an industrial sander and is fine for use with small material and moderate useage, which is what I do, so its fine for me. Grinding paint off of wood? Don't think that's what it was intended to do. PROS: Small footprint, belts track and adjust well, replace easily, it is quite quiet, dust collection fairly good. Contrary to above review, the belt table does tilt up. Price is hard to beat. CONS: This is not a heavy duty machine and it does bog down easily. The ribbed aluminum disc table really sucks as workpieces get hung up in the grooves. I bolted a thin piece of plywood to it to resolve this problem. The worst thing is that there is no metal/cork platten under the belt like on a portable belt sander. Every time the belt seam goes by the workpiece, it causes a thumping sound which is annoying.

Altogether it is a solid machine and good value for the money, better than a hobbyest machine like that hideous plastic Ryobi that costs more. This is a sander, not a grinder.

This tool is complete piece of garbage. I have been a woodworker for 25 years now, and I have a lot of experience with tools. As another reviewer mentioned, the pulley that attaches to the drive shaft fails. It is plastic, and it is keyed to the drive shaft with a spline. The spline is extremely shallow, and the plastic pulley will eventually slip on this spline, making the sander completely unusable. This is not a manufacturing defect. It is a design defect. I want to stress I did not abuse the machine. It broke within a few minutes of using it. The video shows what happens with applying slight pressure. You can see I am barely holding on to the piece of wood. Note, guard removed so you can see the pulley slip. One thing is for certain, I will never buy another Delta tool again.
