    This was a great way to convert my sander to hook and loop!!

    Figured I needed a new pad. Works fine. My complaint is the price. I forget what I paid but it seems it was about a third of what I paid for the sander. I don't need to praise the sander. If you need a new pad you already have one.

  3. Amazon Customer rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★★ and wrote:

    The non-electronic control random orbit sanders require a little soft plastic cfs disk to control the sanding pad speed. Virtually nobody outside the Dewalt engineering dept knows this. I have been to both big box stores in two states and none carry the DW 2488 hook and loop pad, which includes a cfs disk. Other pads are sold without the cfs disk, which is why they are cheaper. If your sander requires the cfs disk, which I believe most Dewalts do, you will not get sanding satisfaction without a functional one. They are a wear item, and need replacement about as often as the pad itself. You will know you need one when the speed goes out of control when lifting the sander off the workpiece. Shame on the big box stores as well as many (most?) tool websites for being ignorant about the cfs disk. I suspect Dewalt marketing is involved to "force" customers to purchase the more expensive electronic models.

    This fit my older Porter Cable 333 sander perfectly. It also converted it from a 5-inch 5-hole sander to the newer 5-inch 8-hole accepted format. 8-hole paper is now the standard and much easier to find. It seems to be built a little better than the Porter Cable version. The pad backer on this model is metal instead of plastic.

    Having a new pad is great. Easy to install, it is a blessing not to fight keeping discs on the sander.

    The replacement pad was the part needed to allow me to use the sander, arrived quickly and is installed and in use.

    after reading which sanders this fit, it was supposed to fit mine, it did not. modifications had to be made to make it useable and the hooks on the pad are very small, the sanding pads fly off way to easy, I would recommend seeing and touching this item in person before you make a decision to pay for it.

    Good adhesion and good performance. I do think that the price could be better but they work great as it goes.

    Just what we needed....our sander had been in use since about 1996 and finally the pad just disintegrated! Motor was fine so the replacement pad was ordered and our latest project completed.

  12. Charles Long rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★ and wrote:

    I have two DW 421 sanders. The older one has had a new pad, the newer one never. I sand alot and prefer having two grits readily available to use. The pads don't hold the paper well at all. The newer one now 3-4 years old and the older one 5 years or older. The 19.99 was around what I gave for the replacement pad at Lowes a couple of years ago. It still didn't help, even using identical sandpaper on both sanders. My old Makita's held the sandpaper much better.

    It worked like a charm. It took 2 minutes to replace the old one with this one. No more vibration or inefficient sanding jobs

  15. Brad rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★ and wrote:

    These DeWALT orbital sander pads are wonderful and do a great job when new, but if you do a lot of sanding work they might only last 6 months to a year and then the sandpaper doesn't adhere to the pads. After talking with a professional and looking at the loops under a microscope, we are pretty certain that heat tends to break/melt the tiny hooks that hold the felt sandpaper. Under a microscope on a bad pad, the little loops are gone and there is a little bump of plastic where the loop was. If the manufacturer used a heat resistant loop material, the pads would last a lot longer. Knowing this, your best bet is to lower the heat factor by using less pressure especially on wood edges and letting the pad cool more between uses.

    I was grateful to get this part in record time and to have it fit & work exactly. Reusing the screws was fine, but took a little muscle and patience. The sander is very old and I was surprised that I was able to get it.

    I think it is stronger built than the one that came on the sander. Easy to install also. Just be careful not to cross thread the screws. Also recommend you blow out your snder with compressed air while you are changing the pad.

    Good price for hook and loop (Velcro) pad to serve as a spare when the original wears out. No issues encountered.

    The pads on the Dewalt sanders lose their hook-and-loop holding capacity after a while, and need to be replaced periodically. This is the only way to do it. It would be better if they lasted longer.

    Not a bad deal. The price is fair. Dewalt is good quality and I can vote for it. Got this one for my Father-in-Law and he is very happy with it.

    I will have to wait and see, the last one I had it didn't last, didn't even make it through a box of sand paper. I love the way it works but if it won't last I will switch it over to one where you stick the sandpaper on it.

    I was frustrated with the sanding discs always falling off and had been pricing a new sander. This new pad made my 10 year old sander just like new. Changing out the old one was a piece of cake and the new one was an exact match.

  23. The Erstwhile Photographer rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★★ and wrote:

    There is nothing wrong with the rplacement pad. It's just that it is vastly over priced. almost a third of what I paid for the whole sander kit.

    Easy to replace and is a huge improvement then the old one that wouldn't hold the sand paper anymore. Makes sanding a breeze

  25. Harry G Stewart Jr rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★★★★ and wrote:

    I bought mine at Lowes because I was in a hurry, paid about same as Amazon. Package says it fits other models but didn't list the DW420, I guess because it's a much older sander. My DW420 came with the adheisive type backing pad and I was ready to change out to the hook-and-loop since I keep buying the wrong discs!To clarify, this DW4388 is a 5" hook-and-loop backing pad that fits the DW420, DW421, and the DW423 sanders.

    Of course this is a quality product. Putting this on the sander makes it almost like new. Highly recommend if you think you want to replace yours.

    When the pad on my DW421 came apart, I needed a new one. Amazon had it (thankfully). Installs with three screws and now my random orbit sander is functioning again. Not sure what the difference is between the DW421K and the DW421, but it worked fine on my DW421.

  29. Martin gross rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★★★ and wrote:

    Obviously, this is the original part and is 100% perfect. Installation is <1 min. with the three existing screws. Makes the sander good as new if you've worn down the pad a bit and have trouble keeping sandpaper disks adhered.My one hesitation is that I recall there used to be a replacement "disc brake" included in older versions of the pad kit. They don't mention it anymore and it wasn't in the box, so I can't complain. However, by the time the pad wears, that "brake" disc also wears out, allowing the random orbit pad to spin out of control (instead of forcing it to keep moving in random pattern). Inconvenient and extra cost to have to track down the little wear item separately.

    This is my second sander pad for this great orbital sander. I use it a lot on a big range of wood projects. The pads are a little soft and do wear but I expect them to wear out at some stage. OK by me.

  31. Earl S. Handy "ehandy" rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★★★★ and wrote:

    This product is a straight forward replacement for a Dewalt hook & loop Pad which eventually will wear out and no longer hold the sanding disks. These pads hold up well and are very durable for years of service. The pad is easy to replace; I recommend locktite or something simular on the threads of the screws that hold the pad on because of all the vibration. This pad is expensive but as long as your sander runs well is worth buying as it's cheaper than replacing the entire sander.

    I used to buy Dewalt tools thinking they are going to last a long time without any problems. Not true and replacement parts are seriously overpriced. $22 for a piece of foam and rubber? I expected that at the price I paid for the Dewalt Sander that I should not run into any problems. I've had to replace the Seal twice and now the foam pad twice. I only use it for light woodworking and not that often either. I should have just bought Ryobi at 1/2 the price and would have been money ahead. I really think that with all the problems I've had with Dewalt tools and Dewalt batteries that somewhere along the way Dewalt decided to cheapen everything, live on their reputation for awhile and somebody pocketed the savings from switching to cheap parts and cheap designs. And by the way, this Pad is Made in China.

    Works perfectly on Makita BO5010. The metal backing appears more durable than the OEM pad on the Makita. Opted for this one after reading negative reviews on the Makita pad.

    After five minutes of using the new pad the screws that hold the pad to the sander pulled thru creating holes bigger than the screw heads making it unusable.The metal on the pad that the screws go in seem to be very thin and not as solid as the original pad.Very disappointing

  35. Terri Solomon rated DEWALT DW4388 5-Inch Random Orbit Palm Sander Pad, Medium (Fits the DW421K and DW423K) as ★★★★★ and wrote:

    What annoyed me about this part was the fact that it is listed as 151281-06 on the paper work that came with my DeWalt DW421 sander. On-line searches quickly confirmed that number was superceded with 151281-08. It was only after a lot of searching that I found out that DeWalt now markets the part as DW4388 with many sites stil using the old number. The new box says it's for DW421 but makes no reference to the part number info. that came with the tool. As to those complaining about the price,once I had the new part number I discovered the the two big box home giants carry this item at a better price and one outfit that came up under the old number using one of the big price search sites is way cheaper along with free shipping. As for the part: it seems to be a perfect replacement.

    My Dewalt orbital sander pad had reached the end of it's useful life. The Velcro on the old pad was not holding the sandpaper in place. I ordered this from Amazon and it came on time and as promised. Easy to replace. Now my old sander works like new again. Worth the money!

    The sanding discs would no longer stick to the pad on my sander. I wasn't sure if it was the discs or the pad. I took a chance and got a new pad. It was the pad! It now takes considerable effort to remove the disks! Works just like a new sander.

    Replacement pad fits exactly as it should and is super easy to replace. Velcro holds sandpaper like new and my only gripe would be the cost of the pad itself. kind of pricey for a simple item but much less than buying a new sander. Overall great product.

    The replacement sander pad ended up giving me two dewalt sanders..After my old trusty sander pad bit the dust i went shopping again. The dewalt had lasted almost ten years so I said why not get the next model up..After getting home I looked at the old sander again and said,"all it needs is a new pad." I looked on Amazon and the rest is history.

    I've had this random orbit sander for about 10 years now, and after years of hard use on everything from sanding the reproduction Stickley furniture I make, to smoothing my amateur plastering patches in my 1920s house, the pad finally failed.

    For this type of item, you'd think it would be easy to find at your local hardware store - not so! Amazon to the rescue...

A fair price and fast shipping - all around good experience.

    FYI, just found out that the Dewalt 421 can use the Makita replacement pad (Makita 743051-7 5" Rubber Pad). The opposite isn't true-- Makita has a bearing that prevents the use of the Dewalt pad. Handy news if this product is out of stock.
