Toolant 7mm Carbide Masonry Drill Bit Set, Shockproof Hammer Drill Bit Set for Concrete/Tile, Industrial Strength - Box of 10

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

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.

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 value

Used these over the past month for drilling into brick, block, and concrete. Each bit cuts cleanly without overheating or wandering, even with a cordless drill. The flutes clear dust well, and the tips have stayed sharp after a surprising amount of use. I’ve drilled 26 holes with just one bit, and it’s still going strong — no chips, no burn marks, and it still bites in cleanly. The set covers the main DIY sizes, and the shanks grip firmly with no slipping. If you’re doing occasional masonry work or fitting fixings into concrete or brick, these perform well and feel dependable. Now I’ve got nine bits left and I’m looking for another project just to use them. Hope this is helpful as I am really pleased to have found bits that do the job prperly,

Only used them a few times but no issues. Good for the price.

Quick delivery, Great quality and drilled my very hard house bricks with no problems. Very pleased

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. Grâce à mon abonnement Amazon Prime, ma commande a été livrée en deux jours seulement, sans frais de livraison. Je suis donc entièrement satisfaite !

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.
