Camdios Glass Cutter 2mm-20mm, Upgrade Glass Cutting Tool with Glass Cutting Oil, Pencil Style Oil Feed Carbide Tip Glass Cutter for Mirror/Tiles/Mosaic.

What it is and why I picked it up

I keep a small roster of cutters in the shop for picture-frame glass, mirror offcuts, and stained-glass repairs. I wanted a compact, oil-fed option I could throw in a pouch without babying it, and the Camdios glass cutter fit that brief: pencil-style body, carbide wheel, an internal oil reservoir, and three interchangeable heads covering 2–20 mm glass. It also ships with oil, a dropper, and a tiny screwdriver, so I didn’t have to hunt for extras to get started.

Build, feel, and ergonomics

The cutter is roughly pen-sized with a knurled alloy handle that’s easy to index in the hand. Balance is slightly forward of center, which helps plant the wheel without forcing me to press down. The grip texture is on the aggressive side—great with gloves or slightly oily fingers, a touch sharp if you’re barehanded and bearing down for long sessions. I ended up knocking down one micro-burr on the handle edge with a Scotch-Brite pad. After that, it felt secure and comfortable.

The cutting heads mount with a small set screw. The heads themselves have flat sides on the block, which gives you a reliable reference against a straightedge; that’s a thoughtful detail I appreciated immediately. The included plastic case is serviceable for storage, though the raised set screw on the head can keep the lid from snapping perfectly shut if you don’t nest things just right.

Interchangeable heads and oil feed

Three heads are included: one each for 2–6 mm, 6–12 mm, and 12–20 mm glass. The wheel geometry and bearing tension feel appropriately different head to head—subtle, but noticeable. Swapping heads takes under a minute with the included screwdriver.

The oil feed is gravity/pressure assisted through the handle. If you fill the reservoir and give the cutter a gentle press on first contact, the wheel gets lubricated consistently during a scoring pass. It’s not a “gusher,” which is good—just enough to leave a faint track. If you’re a casual user and don’t want to store oil in the handle, a single drop on the wheel from the included dropper works fine. I tested both approaches. For short sessions, I preferred the dropper; for batch cutting mirror strips, filling the reservoir saved time and kept the cut quality uniform.

Cutting performance in practice

• Thin window and picture-frame glass (2–3 mm): Excellent. With the 2–6 mm head, the wheel produced that tell-tale continuous “zip” and a fine, clean score. A gentle tap from underneath ran the break with minimal flaking. Edge chipping was tiny—easily cleaned up with a stone.

• Mirror (5–6 mm): Very good. Scoring against a steel rule felt controlled thanks to the flat-sided head tracking along the straightedge. Clean breaks with predictable runs; I had only one instance of the score wandering at an inside corner when I rushed and double-scored—my fault.

• Stained glass and mosaic: Good to very good depending on glass texture. It handled smooth art glass nicely. On heavily textured pieces, the wheel wants a steadier hand and a bit more oil; still usable, but I reached for running pliers more often to start the break cleanly.

• Thick glass (10–12 mm): Respectable for a budget cutter. With the 6–12 mm head and a confident single score, the break ran true with firm taps. For 12–20 mm cast glass, the tool will score, but technique becomes critical and the success rate drops without proper support and a running tool. The included 12–20 mm head is a useful addition, but don’t expect miracles on the upper end without experience.

• Bottles: This is not a dedicated bottle-cutting jig, but if you have a fixture to hold and rotate a bottle, the wheel and oiling do fine. I set up a quick cradle with a fence and achieved consistent scores; thermal shock and tapping yielded clean splits on most wine bottles. Freehand scoring around a cylinder is a frustration I don’t recommend.

A note on tile: The cutter is intended for glass. It will score glass tile well. It won’t cut ceramic or porcelain tile—wrong tool and wrong wheel for that job. If your project involves non-glass tile, use a tile cutter or a wet saw.

Technique that made the difference

Glass cutting is as much about process as the tool. Here’s what worked best for me with this cutter:

• Keep the handle at roughly a 45-degree angle and the wheel vertical to the glass.
• Score once, edge to edge, in one continuous pass. Don’t retrace a cut.
• Listen for a steady, crisp “zip.” A gritty grind means too much pressure or too little oil.
• For straight cuts, run the head’s flat face against a metal straightedge and keep your elbow locked to avoid wandering.
• Start the run with gentle taps on the underside along the score, then move to the table edge or use running pliers. Don’t force a hesitant break—re-tap and let the score propagate.
• Deburr with a stone or 120–220 grit wet/dry paper to keep edges safe.

Durability and maintenance

The carbide wheel on the 2–6 mm head is still sharp after several dozen straight cuts in mirror and picture glass. There’s no side play, and the wheel spins freely. The oil feed is intact and hasn’t leaked on the bench, though I store the tool upright when filled. Because the heads are user-replaceable, longevity isn’t a major worry; you’re not throwing away the handle when a wheel eventually wears. I’d like to see slightly smoother finishing on the handle edges from the factory, but that’s a nit I fixed in two minutes.

One caution: on my sample, the tiny set screw threads are cut cleanly, but you need to seat the head squarely and hold it down while snugging the screw. If you start the screw at an angle, it will feel like it bottoms early and the head can shift. Once properly seated, mine stayed put.

What I liked

• Predictable tracking along a straightedge thanks to the flat-sided head
• Versatile head set covering thin picture glass up through 12 mm, with an option for thicker stock
• Oil reservoir that actually works and doesn’t drench the work surface
• Compact, pen-style ergonomics that make it easy to control pressure
• Useful kit extras (oil, dropper, screwdriver) so you can get started right away

What could be better

• Handle edges benefit from a quick deburr; the grip is grippy, but almost too sharp out of the box
• The storage case is a tight fit with a mounted head; it’s fine for a drawer, less so for a go-bag
• The head swap system relies on a tiny set screw—it works, but a captured screw or knurled thumb screw would be friendlier
• The marketing mentions tile; to be clear, it’s for glass (including glass tile), not ceramic or porcelain

Who it suits

• DIYers and hobbyists working on frames, mirrors, mosaics, and stained glass who want a reliable, modestly priced, oil-fed cutter
• Occasional bottle-cutters who have or can rig a simple jig
• Woodworkers or renovators who need to trim mirror or cabinet glass a few times a month

If you’re scoring thick architectural glass routinely, you’ll still want a pro-grade cutter and complementary breaking tools. Likewise, if your work is predominantly ceramic tile, choose a different tool category.

Value

Given the interchangeable heads and included consumables, the Camdios glass cutter offers strong value. The cut quality is on par with more expensive single-head cutters I’ve used, and the oil feed adds consistency, especially on longer scores. Minor finishing quirks don’t overshadow the overall performance.

Recommendation

I recommend the Camdios glass cutter for anyone who needs a dependable, oil-fed glass cutter for mirrors, picture glass, stained glass, and glass tile. Its strengths are controllable tracking, a genuinely useful oiling system, and the flexibility of three heads in one kit. Be prepared to give the handle a quick deburr and take your time seating the heads correctly. If your projects involve ceramic or porcelain tile, or you demand a case that seals perfectly, look elsewhere. For most glass-cutting tasks in a home shop, this cutter checks the right boxes and does the job cleanly.
