toolant Concrete Drill Bit Set & Masonry Drill Bit Set, Shockproof Hammer Drill Bit Set (5pcs) for Concrete/Glass/Brick/Plastic/Cement/Tile, Industrial Strength Carbide Drill Bit Tip, 4-10mm Box of 5

Good quality masonry drill bits. I have used the 12mm bit and it worked well. Easy to attached to my drill. Good value for money.

I don’t normally leave reviews but it wanted to share this. I’ve been in construction for over 30 years and these are some of the best bits I’ve bought and great value, just go through concrete no hammer drill needed

Good quality drills with flats. Used on concrete project. Used in HD drill no problems thru in no time. Low vibration, drills durable and on size. No slippage under load

Excellent drill bits! This was not a brand known to me, but drilled into brick without difficulty and remained sharp. If you're drilling into brick or concrete and your drill is a variable speed hammer drill, use a smaller masonry drill to make a pilot hole, then use the 12mm drill on hammer setting at medium speed. Be sure to use a spiral brush (also available on Amazon at a reasonable price) to remove all dust from the hole before inserting and securing a security bolt with hanger These 12 mm drill bits are just the right size to drill holes for petzl anchor bolts and hangers to set up a security rope when climbing an 8.6 metre ladder to clean my solar panels. The drills are triangular where they fit into the drill chuck which means they never slip in the chuck. The drills are sharp, durable, and reasonably priced and come in their own transparent top plastic case. I have no hesitation in recommending these drills.

Standard masonry bits really struggled with a concrete lintel, this went through in seconds.

Only used once but went through metal etc so easily. Great price for great drill bits.

These are brilliant masonry drills they go though like a hot knife though butter fantastic

I had to fit a key safe outside our house and hoped these new bits would make my drilling into the brickwork easily managed, but no. I thought they were fairly poor in what they achieved and I had to use a great deal of force to drill the holes. Wished I had used my SDS drill with its masonry bits which would have managed it no problem.

J'ai utilisé l'un des forets de 7 mm de ce jeu pour percer de nombreux trous dans la brique et le béton, et il est toujours aussi solide et tranchant. Je trouve qu'il est d'excellente qualité. Il perce facilement, avec précision et rapidité. J'ai lu d'autres commentaires plus négatifs à leur sujet, mais je suggère aux gens de toujours percer un petit trou pilote dans la brique et le béton, d'environ 3 ou 4 mm de diamètre, avant d'agrandir le trou avec des forets de 6 mm ou plus. Cela réduit considérablement la pression et l'usure des forets plus gros. J'aimerais avoir d'autres forets de ce type.

Très dur capable de percer l ardox avec huile de coupe de qualité et machine pro. Mais peu casser en sortie si trop forte pression. Pour le prix bonne qualité.
