VIBIRIT Glass Cutter Tool Set,2mm-28mm Pencil Style Oil Feed Carbide Tip with 4 Replacement Heads,Screwdriver and Oil Dropper for Cutter Stained Glass/Tiles/Mirror

Used this to cut some big 1/4" Toledo plate glass mirrors from the 1970s. SCARY!!! Big, sharp, heavy.I'm not a professional, but the cutter worked great. I filled it with sewing machine oil, which is similar to 3 in 1, because that's what I had on hand.It's important to hold the cutter as perpendicular to the glass as you can to get a nice score with a clamped on straight edge. Even pressure and score it once, end to end. If you hold the cutter a little sideways and it can make little chips In the edge.Took me a try or two to learn that.Then tap the glass with the other end of the handle of the cutter (ball part) on the bottom of the score to start the crack/run, and then a little lift and release down and pray and BAM! Perfect cut! (Most of the time)

Directions would be nice

I have several kinds of glass cutters. This one is my favorite and the one I always reach for first. It is a nice, solid weight (not too heavy or light) and the textured metal handle keeps my hand steady and in place when I’m scoring glass.

I bought this partly because it offered four carbide glass cutter heads. These are well made and should each last a long time. The cutters appear to be identical, even though they are laser engraved with different numbers in millimeters, which could refer to glass thicknesses.

appears good product. However does not work on 3/8" glass

No instructions so as a beginner I didn’t know which one to use or what the dropper was for. Still done I went with my gut. Not sure if I’m using correctly or not

As others mentioned, the set I received was incomplete. It didn't even come with the handle. The package that came had another Amazon-branded bag inside that was half open, inside that was the actual bag of parts, but it only included 4 of 7 listed parts: screwdriver, dropper, and two heads. No handle, and no extra heads. I've ordered a replacement, will update this review if it's complete and I can actual use it.

Easy to use
