SuperMax 16-32 Drum Sander

Item #
74% of 100

The new SuperMax 16-32 Drum Sander features a patented ''Quick Adjustment Lever'' that raises the drum through its entire 0'' to 3'' height range with an easy pull of the lever. The traditional adjustment wheel still allows fine adjustments, but there is no need to repetitively wind the wheel for larger adjustments. In addition, the patented ''Fast Lever'' permits rapid adjustments for wide and narrow stock. The Turbo Vented dust port uses impeller-like fins to improve dust collection by up to 15%, and a rear-mounted conveyor motor pulls stock through, instead of pushing, to improve conveyor tracking. The 16-32 features a built-in DRO that is paired with SuperMax IntelliSand Technology for easy setup and even sanding without burning or overloading the motor. The SuperMax 16-32 churns out flat, smooth surfaces with unwavering consistency, giving you the benefits of a wide belt sander at a price that won't break the bank. It offers 16'' of sanding width in a single pass and 32'' in a double pass. The 16-32 Drum Sander comes standard with an open stand, and the drum is pre-wrapped with 80-grit sandpaper.


  • Quick adjust lever for fast height adjustment—just pull the lever to go from 0'' to 3''
  • Built-in digital readout for precision and ease of setup
  • IntelliSand™ Technology automatically adjusts conveyor speed based on load, preventing gouging, damaging or burning of stock, providing consistent finish even with varying grain pattern and density, and greatly increasing abrasive planing and dimensioning speed
  • Single alignment point—just one nut aligns the conveyor parallel to the sanding head
  • Indexed conveyor alignment for wide stock
  • Extra-wide conveyor properly supports stock over 16'' wide
  • Thrust bearing eliminates backlash in height adjustment
  • Extra wide space for easy access to abrasive fastening system

SuperMax 16-32
Bought the sander a couple of months ago. Love it. Great for the price. Would recommend it. No snipe. Great deal.
March 28, 2018
Great machine, easy setup
I have owned a Supermax 16-32 drum sander for over a month now and I have used it to sand both wide and long pieces. I was immediately impressed with the quality of the construction and the thoughtful features built in to the machine. The single lever quick height adjustment, the digital thickness display, the intellisand rate adjustment, to the captive adjustment wrenches on the feed conveyor.
Only a minor adjustment was necessary on the drum/table alignment and it was quick and easy to perform following their instructions. The instructions are a little sparse but they give you all the info you need, I guess they assume you have some experience running and maintaining machines.
Running this sander, just like running any other power tool, has a learning curve. I have had a little trouble with snipe, but the snipe is because either I haven't supported the work piece or because I supported it too much. I just finished installing the optional infeed/outfeed table and got it aligned with no trouble. Remember to just snug the four bracket mounting cap screws, or tighten and then back off a half turn. This will allow the 3mm allen screw to move the support brackets into position. Also, don't use the allen to bring the table completely up, leave about 1/4 inch gap. Tighten the two bracket mounting bolts, then adjust the rest of the gap out by raising the table into final alignment and tightening the four carriage bolts that hold the table to the support brackets.
The conveyor belt began running a little to one side, but here again you need to keep an eye on how your machine is performing and make adjustments as needed.
I have had beautiful results sanding a 27" wide by 2 1/4" thick Black Walnut Crotch with no sanding line where the drum ended. The key is to make multiple passes at the same thickness setting. Four passes at one setting seems to work best on wide pieces. The four passes are done this way: Make your first pass, 2nd pass- rotate workpiece 180 degrees, 3rd pass- flip the piece over, fourth pass- rotate 180 degrees. Then lower drum and begin again. It may take a while, but the results are far superior to hand sanding with power tools although I do my finish sanding with 180 and 220 using a random orbital sander. I ordered the variety pack with the 36, 80, and 120 grit strips. The 36 is best for smoothing and flattening big pieces of hardwood. Pine with lots of knots or sap pockets can cause trouble with the resin building up on the belt and not coming off using the rubber cleaning bar.

Woodworking Experience:
Exactly what I expected
A cantilever is never going to be 100% perfect but Supermax makes it pretty darn close. It'll never replace my 20" helical Jet for making perfectly uniform thickness across a board however the intention of this is to make very light passes to cut down on hand sanding time and give you a relatively flat surface then finish out the last 10% with some RO or hand sanding. I started to sand the piece attached here with 80 grit and it would have taken over an hour for me to do going through the grits. I was able to run to Rockler (in town), buy the supermax, put it together and fully sand my piece in less time than using my Rotex 125 would have taken. Totally worth the money and time savings.

Woodworking Experience:
there are definitely pros, but there are definitely cons
Call this review, "what I wished I had known before I bought this". I formed a favorable opinion of the Supermax 16-32 before I bought it, through online reviews and YouTube videos. I have now spent my first day with it, setting it up and testing and learning how to get the most out of it. First the pros, I will repeat what most say about it: it iseems to be of very good build quality, fit and finish very good, easy to assemble, easy to change the sandpaper, wiith pretty clear instructions. My first piece of advice is to trust the factory adjustment. Test the tool by sanding a piece of Mdf (or similar) nearly as wide as the drum but not too long, 18" to 24" long. Use a good pair of calipers to measure the thickness across the width, adjust the table if needed. I found the method described in the instructions to be somewhat less than easy to insure accuracy, you are better off testing, measuring, then adjusting. I was always skeptical that the open ended sander could plane a surface wider than 16" and leave flat results with no hint of the edge of the drum. Though I followed the instructions, I have yet to get such a result, though I can see how there could be other factors accounting for less than perfect results. Now for my biggest complaint. Unlike a planer, this sander has no powered feed rollers pressing down on the board, it uses a conveyor belt to feed the stock and there are two pressure rollers on the infeed and outfeed side of the drum to keep the stock flat. They are not that strong and the feed table is not that long. If you are trying to guide a longer board, anything over about 25", either into the machine or out of it, you have to be very careful not too lift or lower the board out of alignment with the table, it is very easy to make a snipe on longer boards, and they don't have to be that long. It is clear to me now that I must buy the optional in feed and out feed tables. Maybe then I can safely handle 3' boards. I would not trust the machine to give good results on anything much longer than that unless I had 4' - 5' outfeed and infeed tables. The instructions do make this clear, though they don't convey just how easy it is to make a snipe. (The cynical side of me sees that Rockler sells an expandable auxiliary out feed roller made by none other than Supermax. Makes you kind of think they knew all along that their machine needed long feed tables.) I am also pretty sure I would not sand a board wider than the drum (16") unless it had pretty good support on the outboard end of the drum. The short, smaller boards l sanded were great, flat smooth and within a .001" consistent thickness. If you are a box maker this would be great as is. But I had longer, narrower boards to sand (6' and under) and I am very disappointed that it is so fussy. I will buy the tables, but I am certainly going to test it a lot before I run any cabinet stock through, and I have to believe those fairly short tables will need additional support on both the in feed and out feed side for anything much longer than 3'. We shall see. In summation, there is a lot to like about this machine, but my frustration is that I will not get its best performance with out an investment of more time and money than I had hoped to spend.

Woodworking Experience:
Not what I expected.
From the reviews I was so excited about using this machine. Unfortunately installing the belts was far more difficult than I expected. I ended up severely twisting my nuckel causing sever pain.
The feeding of wood had has to be done in such a was that only a small amount of wood is taken off otherwise black strips are left on the wood also the causing the connector ends to prematurely wear out.

Take it for what it's worth...
After doing a lot of research on drum sanders, I settled for the SM 16-32. So far I am not impressed and kind of want my money back! Shall we start with the Pro's?
1. two powerful motors 2. SuperMax is USA based company and owned by Laguna. 3 Fast adjustment lever and Fine adjustment handle operate incredibly smoothly. 4. DRO is a wonderful option that comes standard!.
Con's. After the first half hour to hour of run time, I started noticing white dust everywhere, turns out that the conveyor tension wasn't set up properly and frayed one side of it. After 20 hours now, it is a constant 15 minute adjustment to keep the conveyor straight and I need to order a new conveyor belt. 2. After reading the poorly written instruction, the inside bolts that need to be slightly loosened to allow the tracking arm handle (used for items wider than 16 inches) still doesn't work and leaves lines on wide panels. 3. Adjusting the infeed roller tension is to hard or to loose, meaning that you have to stick your fingers under it to raise it so you can get a board under or so loose that you end up with snipe! 4. The outside adjustment bolt/stud is not long enough for parallelism adjustment, mine is way to short to raise it up properly resulting in shims being made.
I hope someone out there has had a better experience than me!

BEST ANSWER: SuperMax is manufactured in Taiwan.
How hard is it to change the sandpaper? Typical jobs require working down from coarse to fine. It would seem that this is a real hassle on a machine like this.

Is assembly required?
Harold T on Apr 3, 2018
BEST ANSWER: Yes. Though not too difficult, mostly the stand assembly. you will need help lifting the main body on top of the stand. Also, I needed to align the machine and the belt, which is easy to do but also takes time. Any machine requires alignment....
