Types of Sanding Attachments

There are multiple different ways to use sanding attachments, so there are also multiple different types of the attachments themselves. Here are some of the most common:

Sanding Discs

This is the most basic type of sanding attachment and the one you will most often see. Sanding discs are small, flat circles composed of sandpaper (you can choose what grit of sandpaper depending on what you are sanding). These are the most versatile of the sanding attachments.

Angle Grinders

An angle grinder is a more intense type of sanding tool which is often used not for the finer sanding tasks of polishing and finishing, but the more intense tasks of grinding and cutting. Angle grinders also have a flat, circular end similar to sanding attachments, but as mentioned, it is sharper and more intense.

Dremel Attachments

Dremels are probably the best tool mentioned in this article when it comes to multitasking, and one of the many tasks a dremel can perform is different levels of sanding. If you have a dremel, it can be handy to invest in sanding attachment designed specifically for your dremel to maximize efficiency.

How We Choose These Attachments

Because of the wide range of different products, it is important to keep a few crucial qualities in mind when determining which will work best for you. We have compiled a list of the most integral:

Maneuverability

It is likely that, when sanding something down, you will need to move your sandpaper into some pretty tight corners. It can be helpful to have a sanding attachment that is on the smaller side and can be easily twisted and manipulated to fit where you need it to go.

Ease of Changing

The thing about sandpaper is, no matter how durable it may be, it will eventually wear down and can then actually cause more harm than good. You want a sanding attachment where it is quick and easy to replace the used with fresh sandpaper so you can get back to work.

Variety

Most attachments come in a kit. It can be helpful to invest in a kit with a wide variety of different sandpaper grits and attachment sizes so that you can handle whatever project may pop up.

Review of the Best Sanding Attachments for Drills

Now that you know more about the wonderful world of sanding attachments, let’s check out some actual products:

McKay 2' Abrasive Quick Change Discs Roloc Polishing/Sanding Mandrel with a Shank Power Tools Drill Bits Attachment

PROS

  • Well made
  • Durable, will hold up well
  • Will sand quickly and efficiently
  • Mckay provides good customer service

CONS

  • Only comes with one size of grit sanding discs

The Mckay 3” 120 Grit Abrasive Rollock Sanding Discs are the absolute best we were able to find after scouring the market. These discs are the real deal!

They are quick and easy to change out, though it should be noted that you will not really need to replace these discs that often because grinding the disc down will simply reveal more of the abrasive sanding surface, so they will last a long, long time.

Additionally, these are quite easy to maneuver and will be able to fit into the tight corners you need in order to sand those more tricky surfaces sometimes. The provided arbors will fit a wide variety of different discs (although it should be noted that only one type of disc comes with this order).

Bottom Line

The Mckay 3” 120 Grit Abrasive Rollock Sanding Discs are the premiere choice for sanding attachments for drills. Keep in mind that you may need to find other sizes of discs depending on what you are sanding, though.

Sungold Abrasives 74905 Sun-Brite Surface Conditioning Disc Assortment with Back-Up Pad and Storage Case, 2-Inch (25/box)

PROS

  • High quality
  • Will last a long time
  • Can quickly be changed out
  • Endorsed for use by professional mechanics
  • Excellent addition to working with a die grinder

CONS

  • Not great at fitting into tight spaces
  • On the stiffer side, feel more like a grinding wheel than a scouring pad

The Sungold Abrasives Sun-Brite Disc Assortment is a close second choice for a best sanding attachment for drills, right behind our first option, the Mckay 3” 120 Grit Abrasive Rollock Sanding Discs. But do not think there is anything secondary about the Sungold kit!

These are excellent for a wide range of different activities – users report they are effective at cleaning off rust, polishing metal, cleaning surfaces you intend to seal or to paint, removing sharp edges from metal objects, finishing off a surface (and most particularly, an aluminum surface), and removing gasket materials.

Plus, these discs come with a fantastic storage system. The whole ensemble consists of a case, a holder, and thirty-five discs. The holder is separated into nine different compartments so that the different types of discs are easily kept separate and organized.

And you get four different kinds of discs with this product: gray discs that are super fine, blue discs that are very fine, maroon discs that are medium, and brown discs that are coarse.

Bottom Line

The Sungold Abrasives Sun-Brite Disc Assortment is a fantastic example of a great sanding attachment product. It is not the best at getting into tighter spaces, though.

Best for the Money:
Woodstock D3292 Drum Sanding Kit

Woodstock D3292 Drum Sanding Kit, 16-Piece

PROS

  • Easy to use
  • Solid and sturdy
  • Great for use with power hand drills and drill presses
  • Particularly great at smoothing curved edges, both on the insides and outsides of wooden shapes

CONS

  • Sandpaper is too coarse for finishing work
  • Rubber on the inside of the attachment is not particularly stiff and it can be difficult to attach the drum to the spindle

If you are interested in finding yourself a high quality sanding kit that will not completely destroy your bank account or budget, it will be difficult to find a kit that walks that balance better than the Woodstock D3292 Kit. You are not compromising anything at all when you go with this, and you are saving your wallet quite a pretty penny.

This kit comes with a variety of different drum sizes: a half inch drum, a three quarters inch drum, a one inch drum, a one and a half inch drum, and a two inch drum, along with quarter inch spindles and three – count them, THREE – medium grit sanding sleeves included for each of the five drums.

That’s quite a bit for the price! And it is simple and easy to use – it is straightforward to install the sandpaper on the mandrels, and since the biggest attachment is still only two inches, it can be easily maneuvered to fit into really tiny spaces.

Bottom Line

While you may struggle a bit to attach the drum to your drill spindle, the Woodstock D3292 Drum Sanding Kit is a top notch option that will not break the bank.

PROS

  • Best option for a sanding disc
  • Durable, will last for a long time
  • Discs can be changed out quickly
  • Versatile, can be used for a variety of projects
  • Sturdy attachment system will hold discs in place

The DRILLPRO 70Pcs Sanding Discs Set is far and above the best sanding disc set we were able to find. This set has it all! It comes with three different kinds of discs. The black high performance discs are designed for working with stainless steel, plastics, aluminum, ceramics, and concrete surfaces.

The zirconium oxide discs are great for polishing hard metals and removing rust. And the aluminum oxide discs are ideal for general grinding, deburring, prepping a surface, and removing paint, AKA the rougher tasks.

Users report that they are able to use the range of different discs on a variety of projects, including cleaning gaskets, resealing automotive engine surfaces, and detail work on their smaller projects.

Bottom Line


The DRILLPRO 70Pcs Sanding Discs Set is the premiere option for sanding discs that you will be able to find. Keep in mind that working with this product can get a little messy, though.

Katzco Grinding Wheels – Flap Grinding Wheels for Angle Grinder - 5 Piece 4.5 Inch Finish Work, Deburring, and Light Grinding - Size 4 1/2 X 7/8 Inch - Grit Aluminum Oxide - 40, 60, 80, 120, 180 Grit

PROS

  • Best option for an angle grinder
  • Excellent at shaping and polishing
  • Katzco provides good customer service
  • Great for sharpening lawn mower blades

CONS

  • Not particularly well made

The Katzco Grinding Wheels for Angle Grinders are the best option for an angle grinder. It comes with five different wheels, all with different grit sizes. The coarsest wheel is excellent for removing scratches and defects from knife blades, and it will not leave behind any ugly marks itself.

It is also great at removing rust, excess material from other tools, and for cleaning up welds that may have turned out a little bit rougher than you originally intended when you were working on them. These wheels also happen to be excellent at finishing carved wood pieces, so they are truly quite versatile. There really is not much to dislike about the Katzco kit.

Bottom Line

The Katzco Grinding Wheels are a fantastic set that can really do it all for you - from polishing up a carved wood piece until it shines, to scrubbing off those scratches and imperfections from your knife blade. Just keep in mind that, although the wheels work well, they do not look or feel particularly well made.

This kit comes with thirteen fat sanding drums, thirteen skinny sanding drums, twelve 180 grit sanding discs, twelve 220 grit sanding discus, twelve 240 grit sanding discs, four small polishing wheels, four large polishing wheels, one polishing cone, one package of polishing compound, two aluminum oxide grinding cones, two silicon oxide grinding cones, one steel bristle wheel, one nylon bristle wheel, five different collets, one high speed cutter, twelve small cutoff wheels, twelve medium cutoff wheels, one large cutoff wheel, one large reinforced cutoff wheel, one grinding wheel, one grinding stone, and one collet wrench/driver.

3M Perfect-It Ultrafine Foam Polishing Pad (05708) – For Paint Finishing on Cars, Trucks, Boats and RVs – Double-Sided – 8 Inches

PROS

  • High quality
  • Best option for a floor buffer
  • Durable, will last for a long time
  • Good for use on farm equipment
  • Great for cleaning up foggy headlights

CONS

  • Can be difficult to clean the pad after use

The 3M Perfect It Ultrafine Foam Polishing Pad is the best option for a incredibly top notch floor buffer. It can be quickly attached and detached from your polishing tools, and its attachment system will also automatically center the polishing pad on your attachment.

This centering will reduce vibration and wobbling, and will ensure you are getting the most efficient polish experience. It is fantastic also for polishing the finish on your car, particularly when eliminating tiny scratches and swirl marks in the paint. This system is effective even when working on cars with darker paint colors, whose paint defects are more readily noticeable in the sunlight.

Bottom Line

The 3M Perfect It Ultrafine Foam Polishing Pad is the ideal polishing pad, with a number of qualities that make it the premiere in floor buffers, and also ideal for polishing up your car’s paint job. It can be a bit of a hassle to clean the pad off after you are done using it, though, so keep that in mind.

  • Good quality

  • Drums hold firmly and are easily changed
  • Durable, will hold up even under constant use
  • Great at shaping knife scales and at smoothing out finished woodwork

CONS
