  • Nice compass tool!
Size: 12 Inch
I just got this compass and it was a pleasant surprise. Hefty metal construction and it has positive thumbscrew to keep the distance adjusted. An interesting surprise is the warranty that says they will replace or refund your order NO MATTER HOW LONG YOU OWN IT. Hard to beat that!

  • Surprisely useful
Size: 12 Inch
The body is stiff enough to do the job, and the points at the end both hold it in place, and etch the wood. The pencil is nice, but I found I preferred to etch the surface of the wood and then follow along with a 0.5mm pencil so that I could see it.

  • Large Compass
Size: 12 Inch
Great product for the price. I needed to trace an 8" circle on a wood cutting project and it did the trick. Standard sized pencils fit in the loop for marking.

  • Not professional, not even percise
Size: 12 Inch
Review for the 12" compass divider. This divider is very sloppy, I can move the two halves about 1/4" (See the photos) Additionally most of the grinding looks like it was done with an angle grinder. This is not a precision machine tool, There are gouges in the metal, and the rivet that holds the two parts together looks like it was hit with a hammer multiple times. Perhaps, in some vain effort to make it less sloppy. I returned it and will order a more expensive/ Better quality one. I gave it three stars as it does function as a measuring device ( You can set the points on the two areas you want to measure, lock it down, and then measure the distance between the two points.) But it is not useful for drawing circles, nor for stepping off a consistent location for drilling holes. ... show more

  • Great birthday present
Size: 12 Inch
My Son got me these for my birthday because I was so sick of trying to find something round in my shop to make curves or circles. Its very sturdy and makes my life easier doing wood projects!
