Question: If I already have the multi-tool attachment (with sander), why would I need this?
Document: Expecting that the whole Matrix line will probably be dropped or become unavailable in a short time, I bought ever accessory I expected to need. replacing my giant old 18V set that had a sander, jigsaw, circular saw, and drill. More power than the old set, stores for months and still has a charge, and all fits into a decent sized tool bag instead of a giant case.Bathroom door was sticking due to moisture swelling at Winter's arrival. 20 seconds with the sander head and problem solved.
This tool and Black and Decker Matrix system made you , man of man.hahahaha.This 'Sander attachment ' include six sander patch.I think , It is very fully amount
My son wanted this for Christmas. He  just got a new house and I thought this set would get a lot of use. He loves his black& decker set he got for Christmas. They work great. The tool bag is awesome. Lots of pockets.
Great attachment for my 20v Matrix drill!! Great for small projects around the house. I would recommend this to anyone needing a quick sanding..
I don't know that I would get rid of the handheld sander just  yet - but in many applications this wins as part of the set.
I go this for my 20v Matrix Drill and it works amazing. I like the Matrix system since I can have numerous attachments and not have to deal with keeping up with numerous tools. The sander works great and being hooked to the drill make sit easy to hold. The unit includes a few things of sand paper, but since this unit has a normal size sand paper you can use any that fit it by just buying whatever grade you need from the store.
So with doing a little research I found that the Bolt-On is manufactured by Black &  Decker. All of the Matrix attachments fit the Bolt-On fine, so no more waiting for attachments. Feel free to call Black and Decker, they can confirm!Don't think I would get rid of my electric sander but this does come in handy when your on a job and  don't have access to power.
I originally saw this as the &#34;Bolt On&#34; drill with attachments at Sears. I saw the great potential for a weekend user like me to have one motor with almost every conceivable attachment. It quickly sold out at Sears and I went to all their catalogs, nearby stores, etc. and could find nothing until I saw an ad on Amazon that looked like the Sears tool. I bought one attachment just to see if it worked.
Purchsed it as I have all the other attachments and rather have it and not need it vs need it and not have it.
I needed a power drill and a new sander, so this Black and Decker attachment worked out. The sander is small enough to get the detailed areas, but big enough for any furniture project. Arrived quickly and good quality.
Answer: yes
