Quality of materials and fit and finish is pretty good. all metal parts actually are chunkier than they need to be, and--a happy surprise--the only plastic part is the molded dust cover on the lower end of the motor. No sharp corners/edges anywhere. It comes with all hex wrenches needed for all the hex fasteners, but there are a few Phillips screws as well. The supplied wrenches are the usual cheap soft IKEA-quality steel, so don't go reefing on them or they'll strip out. The chuck key appears to be hardened tool steel and made very well.Speed control is achieved via a sliding switch on the outboard power supply, which has the shortest AC cable I've ever seen on a power supply; an extension cord is necessary. I get it; this helps keep the price low.This uses a brushed DC motor (looks like a Chinese copy of a Japanese Mabuchi) and it runs smoothly and quietly. The quality of the toothed belt and pulleys is excellent, but there was too much tension. Toothed belts do not need to be as tight as a flat or V belt; in fact, bearings last far longer when a toothed belt is on the loose side. The roller bearings all look good and work smoothly with no crunchiness or noise. The bearings on the vertical carriage slides feel like linear bearings; if they are, this is a nice feature. There's less than .001" of wiggle in the moving carriage.The listing claims 40mm of quill travel; it's actually a bit less at 37mm. The quill handle felt a little loose and the cause was the jam nuts on the two end pivots: the screws were loose in the carriage. I snugged these up and it tightened up the feel, but there was a little crunchiness in the swing so I added a drop of oil to each of the three pivot points and that cleared things up nicely. The Nylok nut was a little snug on the handle pivot so I loosened it 1/8 turn and it's just about perfect.The San Ou branded chuck is marked 1.5-10mm capacity, but it reliably grips a drill measuring .030"/0.76mm diameter. The chuck felt crunchy and dry, but after I added a drop of 20w oil it really smoothed it out and it spins nicely. I didn't expect perfection and you certainly don't get it at this price; runout on a drill shaft is .005" at the jaws and .007" 15mm below the jaws. The runout is in the chuck and not the quill shaft. A better chuck will correct this if you want to spend the $$ or need more accuracy.Performance is good for the intended purpose; it drills soft plastics, wood, aluminum, and steel with ease up to a 1/8" drill size. Anything larger in diameter stalls the motor and requires a more power to be reliable. But this little drill press is not intended to make large holes in anything. Just because a chuck accepts a 10mm drill doesn't mean it's going to work. This has about the same power as a large Dremel, but with lower speed and better low-end torque. All of the 1/8" shank drills and cutters I use with the Foredom work well in this little drill press.If you're looking for hobby-level performance at a decent price, this seems like a good choice. I'm happy with it because it's accurate enough for my scroll saw work, PC boards, and other small drilling jobs. If you need real precision, e.g., clockmaking/jewelry/etc., buy a better tool because you'll end up spending more to get this one really dialed in.
