Round Handle Shank Concrete Wall Drill Bit Hole Saw Cutter Cement Stone 30 40 50mm SDS Plus Shank Hole Saw Wall Concrete Cutter Drill Bit for Brick Stone Cement（Silver）

Used in breeze block. Worked perfect.

A very good product at a price that belies performance. The drill bored through the inner and outer walls in about 12 minutes. I would highly recommend this product. Hardly worth the expense of hiring one and you get 3 sizes of tungsten boring drills. And Amazon deliver next day!!

Fitting a washing machine needed a 40mm hole through a wall. Worked fine with an sds drill, like hot knive through butter. Central drill bit did fall out but easy to refit

Great product for the price,cut straight through a double brick wall with no problem.

This item was great, and cut the hole I needed. However, as many reviews state once used, it's near impossible to change the cutting head.

I needed to drill 1 35mm diameter hole through the bathroom wall for the waste pipe. I was going to hire a percussion drill and masonry bit from speedy hire at about 60 pound for 1 day.I then searched amazon bought this, although was a bit sceptical that it was any good being cheap. I had my own 110 volt drill and transformer, and started to drill. I was pleased with the progress through a 11 inch cavity wall. I kept the tip cool by dipping it in water and completed the whole operation in 20 minutes. I did use the 50mm bit on the idea that if this wore out halfway through, I would continue with the 35mm one. But did it and have the drill bits to use again and again. For the money it is a 100 percent good purchase.

Did the job I wanted them for well protected with oil and the plastic cases for them are good 👍

Cheap(Expensive) Chinese product, works well on soft brick but struggles on common house brick. Simple design not meant to last hence the price.

Parfait pour un usage domestique.

Gute Idee, dass der Bohrer mit einer versenkbarer Imbusschraube festgeschraubt wird.Natürlich wird die Schraube mit der Zeit locker. Entweder immer wieder anschrauben oder wir ich einkleben.Durch Beton und Stahlbeton, wenn man den Stahl / Bewährung nich trifft geht sehr gut durch.Meine Meinung. Ist zu empfehlen.

Usata per creare passaggio cavi videosorveglianza. Sicuramente prodotto non professionale ma perfetto per la mia esigenza. Consigliato

Kommer passa perfekt vid håltagning för AC- dränering.

Necesitaba hacer un taladro de 50mm en una pared de 30 cm de ladrillos macizos para poner un aire acondicionado y por el precio de todo el kit no esperaba mucho, ha hecho el agujero y ni se ha inmutado, ha taladrado muy rápido, lógicamente sacando cada dos por tres la corona para vaciarla. He utilizado un taladro combinado de 1500w y con el percutor activado y al finalizar el trabajo la corona está como si no hubiese trabajado, está hecha de buen material, muy duro. No sé cómo se comportará en hormigón, tampoco son coronas profesionales, pero en paredes normales incluso de ladrillos macizos no sufre el más mínimo desgaste
