Rockler Disc Sander Angle Jig and Circle Sanding Points

Fine-tune miter angles, adjust the length of boards and edge sand perfectly dimensioned circles with this handy disc sander attachment.
Item #
84% of 100

Sand precise miters, square the ends of pen blanks, fine-tune the length of boards, and sand circles all with just this jig and an ordinary disc sander. Thanks to its pivoting fence and large, easy-to-read protractor scale, you can hold your workpiece at the precise angle required, every time. And straight edges aren't the only thing it can do. The jig includes a miter slot that holds a steel pivoting point and stop for sanding circles and outside radiuses. The jig is built on a 12'' x 15'' x 3/4'' MDF base and can be attached to any disc sander with a standard 3/8'' x 3/4'' miter slot and at least 3'' of distance between the front edge of the miter slot and the disc.

In the event that you lose or misplace the steel pivoting point that came with your Rockler Disc Sander Angle Jig, it's nice to have a couple spares on hand. The points slide into the miter slot and rest against the stop, allowing you to easily edge sand circles and semi-circles.

I have Delta belt sander with 12” disc. Easy to saw jig table to correct size. I rarely used disc sander, but with this jig I’m using the disc sander often. With little adjustment angle gage is very accurate.

Angle Sanding Jig
This jig is quite useful and well-built, but it does require customization. In my case, fitting it to a Jet combination 6" belt/12" disc sander required moving the track that fits into the sander's table grooves. The jig has an included track for doing circle sanding, but it is not the full length of the jig. I replaced it with a track that runs the full length so that I can place the circle stop and pivot points anywhere on the track. For this price, an Allen wrench that fits the circle stop should be included.

Expensive for what it is.
Only use the left side of the fence. Pretty much every disk sander I have ever seen, the disk is only usable on the *left* side, so stay on that side of the disk.
The stop / pin point works well! You can sneak up on a perfect circle, and the method accommodates stock that isn't even close to being round, which is nice.
It wouldn't be that hard to make one of these, but getting the details as right as this would be hard.
If you mostly use your disk sander for flat sanding, or rounding over bigger work, the fence will get in your way. But, if you need a bit more precision than a piece of painter's tape on your table to establish an angle, this system is pretty cool.

well built ..
Had to adapt to my disk sander and calibration was not easy. 45 degrees to right side does not match left 45. I have to reset when I switch sides.

Would have loved to have kept it
Ordered it online with free shipping. Price was $79.99 with the original price being stated at $129.99. It would not fit my Porter Cable bench sander miter slot, which I thought was odd because Porter Cable is not an off brand. So I had to return it. IMO, they should have an adapter miter bar for the PC slot, because I was looking forward to owning the product.

I’m giving it one star because of that and because the Rockler site claims it’s on sale at $79.99, saving $50, but when I went to return it at my local Rockler store, it was on sale for $53. Purchasing AND returning this was time consuming and an unsatisfying experience.

My miter slot is 2 7/8 inch from the disk. Can I trim 1/8 inch off the Rockler jig?
Larry H on Dec 9, 2016
BEST ANSWER: You will be right at the aluminum fence edge when at a 45 degree angle (left and right) at that length. You could probably sand down the fence if you so desired to get it to fit (the fence is chamfered at the corner already on the rh side. You will end up having to cut a chunk off the corner of the aluminum angle fence going to the lh side if you want to use both sides of the angle gauge.
What is the largest circle diameter this will sand?
Wayne Y on Feb 18, 2017
BEST ANSWER: You trim to fit the jig base to fit your disc sander; as the miter slot distance is a bit different with each model. So the max diameter if more based on your machine & you can also place the t-track to the back of the dado slot on the jig once it is cut to size. I think the max is approximately 18 inch diameter.
Can this item be placed on the plate of a Jet 12 inch disk sander that has the miter slot perpendicular to the disk?
Philip E on Dec 4, 2016
BEST ANSWER: There are no Jet disc sanders that lack a miter slot that is parallel to the disc. Some have an added one perpendicular, but I cannot find any at the Jet site that don't have the parallel slot needed for this Rockler jig.

Will this jig work on the Rikon 50-120 10” disc sander?
Timothy T on Feb 24, 2019
BEST ANSWER: YES. That’s what I use my Rockler jig with. The supplied mitre gauge from Rikon can’t hold a candle to the one from Rockler. If you follow the instructions, the results will be dead on.
How is the angle guide locked in place?
Randy K on Dec 31, 2016
BEST ANSWER: There is a dado arc channel cut into the underside for a T-bolt to slide along and a 1" knob on top to lock the fence into place.
What sanders will this jig fit?
Paul W on Jun 28, 2019
BEST ANSWER: The product packaging does not specify sander types. However, I purchased my sander from Harbor Freight; it's made by Central Machinery. I had to file the miter slot to make it wide enough for the jig to fit.
can i make this work with my shopsmith? the miter slot seems to narrow even though it measures 3/4 in.
james k on Feb 3, 2019
BEST ANSWER: I do not have a shopSmith. The only reason that It woiuld not work is if the miter slot is not the correct size. I would look at your shopsmith manual for the spec on the miter slot to see if it is of the appropriate size. If you do not have your manual, you should be able to find it online.
Will this work on the Ridgid sander?. Sander has a osculating belt.
Baer on Aug 4, 2018
BEST ANSWER: I don’t see why not. I have the Ridgid oscillating sander and do not have problems.
I have a Porter Cable 8 inch disk and belt sander. Has anyone used this device on that sander. If the miter slot is not perfectly parallel to the disk face, is there an adjustment to better align it. What is the benefit of this device compared to the miter guage that comes with the sander?
steve on Feb 16, 2017
BEST ANSWER: Yes, that is why there is a hair line indicator to help adjust the jig to zero for this type of situation, granted there is a limited distance to adjust the hairline to. Are you able to fine tune the sander lip with the miter slot to better aligned? Miter gauges that come with tools, the angle is typically mounted to the bar, so there is no adjustment to align zero to the actual zero - your point on the miter gauge may be a 1/2 degree one way or another off zero. This jig allows you to set zero so you aren't doing the math to compensate.
can this be used on a DEWALT DW745 table saw?
Koals on Jan 25, 2020
BEST ANSWER: I can’t imagine it was designed for that. However, assuming you plan to use a sanding plate on your table saw, it might work. I tried mine on my powermatic, and to my surprise it fit. The base is 12” so it depends on the distance between the mitre gage slot and the sanding disc. Of course a dedicated disc sander would be better.
i have this jig, and i do really like it, but am curious about something?? for a disc sander that spins counter-clockwise (i have the rikon 50-120), the piece i'm sanding gets pulled from the fence using the setup in the product pictures. feel free to tell me if it's just me, but was just wondering if anyone else experienced this?? does seem to make sense. thanks . . . john. sorry if this is repeated . . . i didn't see my previous question show up.
John C on Sep 14, 2019
BEST ANSWER: I have the same setup. Just hold workpiece tightly and press against disc lightly.
I own a Jet •J-41002, 2 in. x 42 in. Bench Belt and 8 in. Disc Sander - 577004. The miter slot is only 1/4" deep by 3/4 wide. Will this sled work on this sander?
Don W on Feb 9, 2017
BEST ANSWER: The miter slot runners that come with this jig are designed for a 3/8" deep miter slot. One could purchase or make two runners that would fit into the miter slot and get past that aspect but, I would be concerned that this jig would be to large for a 8" disk. It is well built, was easy to install and will be an asset to the shop but i believe that you will only gain limited benefit using it in unison with an 8" disc.
Understand the 3" min distance - what is the max.? ( the inside of the miter slot to the disk is 5" on my large powermatic sander) ie I don't want a gap between the jig and the sander disc Thanks
TOM B on Jul 25, 2018
BEST ANSWER: I'm not sure exactly what you are asking, but there are 2 rows of mounting holes for the miter bars due to the variance in miter slot distance between brands. I would move the bars to the back row, and measure where you can trim the base to, to not have the gap (you will want a slight gap so that the sander doesn't lift and grab the jig while in use). There are instructions you can download above to understand how to set it up for your sander.
On my Jet 9" disc/belt sander the disc is on the other side of the belt turning clockwise, now what?
Paul R on Feb 18, 2018
BEST ANSWER: In this case use your right hand side side from the center of the disc to sand. You want your work piece to be push down into the support table while you are sanding. That is also why the jig has 2 sides that the fence can swing.As long as your sander has a standard size miter track, this should still work. The swing fence is also there to help sand miters on 3D moldings, for example, that can't be flipped upside down to sand.
