MIBRO 460271 Adjustable Circle Hole Cutter, Silver,Black

Used it only once and done the job just fine.

Circle cutting tools for use in a woodworking drill press are hard to find in the UK. What can be found are often rather expensive, even thought the very same thing sells for far less in the US or elsewhere! Rip-off Britain, eh? But this one is inexpensive despite working very well.Some circle cutters are also rather more complicated, requiring a very accurate set-up to get them to do what you want them to do. Some have cutting blades that are awkward or impossible to easily sharpen. Not this one. One reversible blade that's: substantial; stays sharp for a good while even when cutting plywood or MDF with all those blunting glues in them; and is a simple shape easily sharpened by the user.One small negative is that the blade is not easy to extract, for reversing or sharpening. On the other hand, this means it isn't likely to ever go adrift when working.

I needed to make some accurate holes about 50mm in diameter in hardwood and the Mibro hole cutter worked well for that.I would be hesitant to use it on steel or plastic - it might well work.But it MUST be used in a drill press as stated in their instructions - it could be disastrous in a hand drill.

I bought this product to cut a hole in a piece of spalted Japanese cedar & fill it with a disc of spalted apple wood that had interesting features. It came with the cutter damaged at both ends and blunt. I sharpened the hole end of the cutter; it cut a good hole. I decided the disc end was unsharpenable. I ordered a second product, which, true to Amazon form, arrived next day.It arrived with a cutter irrecoverably jammed into its hole by force, mounted 4mm short of the drill bit point, 6mm less than the proper distance. The disc cutting end was inaccessible. I thought it useless & dangerous & returned it. Having no alternative (except buying a third one!) I sharpened the disc cutting end of the first cutter. It was difficult & took time.The idea & design seem promising, although hampered by no accurate means of setting diameters. The product itself is poorly made. I guess it is assembled by poorly trained & paid, demoralised workers with no effective quality control.Job done eventually, but reluctant to recommend the product.

I used this thing once and it got shoved on a shelf straight after. Duller than a dull thing from Dullsville. Don't bother buying this thing folks. It's cheap for a reason.

Does a good job

Works well as advertised

Corta bien sin forzar la herramienta aunque cuesta trabajo ajustar a la medida que quieres, no trae escala.

I've looked and tried a lot of these cutters and never could find one that the knife was strong enough to cut hard wood properly. this one does it perfectly no matter how hard the wood is and works for the next project perfectly. Thank you for a great cutter. Don C

Very good but take care, it's a very sharp high speed tool

Mibro's dirt cheap 460271 hole cutter is not a "world-class" tool, but when you consider what it does for under ten bucks it comes close.Pros: simplicity, stiffness, balance; it's easy to sharpen, and it really will cut any size hole from 1" to 6",Cons: no built-in measure, requiring a little extra setup time. This weighted tool may be unwieldy or dangerous in a hand drill.Used in a drill press, it cleanly and accurately cuts holes. If used with a hand-held drill, I strongly recommend using a pilot hole to prevent the weight from overpowering your grip.Very inexpensive tools are hard to rate fairly. This is not an exquisite example of the best in the industry, but it compares favorably with options that cost $25 to $50. It also does a better job than traditional hole saws in producing a clean edge, and it avoids the enormous torque requirements of a large Forstner bit. It will also cut whatever size you need, for instance a 3-7/16" hole. That just isn't available in conventional tools. To me, this list of versatile features makes it a five-star.

This fly cutter is fairly heavy and seems well made. The allen bolts hold the drill bit and cutter and radius adjustment securely. As far as I can tell everything is properly aligned. My application involved cutting wheels of thin plastic in a drill press with the drill bit removed (no centering hole), and it worked perfectly for this. I also tried cutting wood and it seemed to work well.I'd give it five stars for being inexpensive and doing what it should, but I took off a star because the cutter arrived in very poor shape. The back of the cutter was very rough ground and hollow at both cutting edges, and the tip on the circle cutting end was broken off! Because of this it took a lot of lapping and grinding before I could sharpen the tool. With a flat back and a hollow-ground end, the cutter is easy enough to hand-sharpen.
