100mm HSS Bi-Metal Hole Saw, Red Finish Corn Hole Cutter in 30mm Cutting Depth for Wood Boards, Soft Metal Sheet, Drywall and Plastic

Just perfect for cutting holes for downlights. (That is what it is sized for)It arrived earlier than expected, drilled 4 holes, lights now installed, what is not to like.

For light duty, this saw blade worked as well as could be expected. Not tried on metal. It needs a reasonably powered drill that has adequate torque to spin it.

I've needed a hole saw to guess what? Yes that's right, to cut some holes in my desk.This is definitely not the highest quality tool out there, but it did cut the holes I needed and I still have both of my eyes and all of my fingers which is a huge bonus.I might never use it again but if you are like me and just want to cut a few holes then I would recommend buying it.

Does exactly what you'd expect. I used it to drill a 50 mm hole in plywood. The device itself is easy enough to attach to a standard drill and the hole it produces is nice and neat.

Great Hole cutter. Used to cut a hole for a turret for my diesel heater install. Was a little apprehensive for the price, especially as its only going to be used once (hopefully). It went straight through my van floor no issues, used a little oil for lubricant and was surprised how easily it went through. great addition that a centre drill bit was included.

Done exactly what it was made for

I think it's not strong enough to the job

I needed this for a small job to putting a couple of holes in hardboard to feed through a grommet and cables. Although I managed to do that with reasonable success, it wasn't the greatest. It was made difficult by the fact that the drill bit on the inside was slightly off-centre and wobbled a little. Once the saw edge bit the surface of the hardboard however, it got the job done without making a mess.Some people have mentioned the issue that the inside drill bit is loose and falls out. If you look closely on the shaft of the hole saw however, there is a tiny securing bolt for the central drill bit which can be tightened up using a 2.5mm allen key (see photos). I have no idea why it didnt come already secured, but tightening that up made things easier. The spring isn't secured and can still fall out with gravity however, so be wary of that.In all, it worked as a reasonably inexpensive solution for the job I needed done, so no complaints here. If you need it for jobs requiring fine accuracy to NASA standards however, then you should probably spend a little more money on something of better quality.

Ik zocht een goedkope gatenzaag voor een formaat dat ik enkel nodig had voor 5 gaten. De gaten zijn mooi uitgesneden. Ik kan niet zeggen of ze lang zal meegaan omdat ik dit formaat normaal niet nodig heb.

Hat seinen Zweck erfüllt und ist selbst nach mehr maligne benutzten immer noch nicht stumpf

Die Lochsäge ist an der Nahtstelle auf 'Ecke' gelötet und daher unrund. Vermutlich durch diese unrunde Naht frisst sie sich bei stärkeren Blechen (in meinem Fall 4mm Alublech) fest. Dies ist durchaus gefährlich, da einem dadurch - z.B. beim Einsatz im Bohrständer - das Blech aus der Hand geschlagen wird.Ergo: Nicht empfehlenswert !!!
