Circle and Straight Glass Cutter, Adjustable Scaled Compass Glass Cutting Tools for Circle, Small T Type Glass Cutter for Straight Cutting

You will need a running board for the T to slide on. It’s not level with the scoring wheel. The triangle center for the circle cutter works great. It makes at smallest about 2 1/2 in circle. Good sturdy tool. I use it almost everyday. So far it still makes good scores. Very good tool for the price.

This is a really inexpensive version of a stained glass strip cutter. As I only had one small project, I didn't want to spend a lot of money cutting strip glass. However, it worked OK as a cutter, cutter points were sharp and the cutter head could be rotated to other cutting heads. I didn't try to use the circular part. But, The scale is worthless, as I had no real idea what the scale readings represented. Best to accurately measure from the cutting point to the back edge of the slide. Also don't know what they mean by a standard board; could be a 1 X 4???. Anyway, you have to build a slide mechanism to make it work. I gerry-rigged a cutting board and so far so good.

Does the job well

Pretty cheap. Dont waste money on this.

Haven't used it yet but looks like good quality

Very crappy cuts uneven circles because there is no suction cup, do yourself a favor buy one with a suction cup.
