This was well built, Strong, Cuts pefect hole. Did numerous holes through plastic with no issues

For the price its great,only used on plasterboard so far but cuts through with ease

Cuts ok only used on plastic and wood the spring waste push out unit did not work on the materials and thicknesses that I was working with ( making nest boxes)

Very good, works best after drilling pilot hole

Great tool

but the teeth seemed to burr off when cutting a tap hole in a graphite sink...to be fair it doesn't state it's intended for cutting this material and it eventually got through and left a very tidy hole so for the money it's done the job for minimal outlay.

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.

Not the best not the worst. Nearly set fire to the mrmdf xD. Did its job.

Will not drill through hardwood. I tried to drill beech, no luck, it is unable to drill through. I doubt very much if it would be able to drill aluminium.

Diese 70mm Lochsäge hat genau das gehalten, was ich mir erhofft habe! Ich habe sie für den Einbau meiner Deckenspots verwendet, und sie hat sich als perfekte Wahl erwiesen. Die Schneiden sind scharf und präzise, sodass die Löcher sauber und ohne Ausfransungen geschnitten wurden – selbst in Gipskarton und Holz kein Problem. Die Verarbeitung ist hochwertig, und dank der stabilen Aufnahme sitzt die Lochsäge sicher auf der Bohrmaschine. Auch nach mehreren Einsätzen zeigt sie kaum Abnutzungserscheinungen. Fazit: Wer eine zuverlässige und präzise Lochsäge für Deckenspots oder andere 70mm-Ausschnitte sucht, wird hier nicht enttäuscht. Klare Kaufempfehlung!
