Le top du top . J’ai réussi à percer un mur de 40 cm en diamètre 5 cm. Rien qu’avec une visseuse à percussion à batterie de chez Lidl. Incroyable ce trépan. Très solide, on peut même le brancher sur une perceuse SDS plus et SDS Max. J’ai impression que c’est encore plus solide, que ma bosch qui me coûte cinq fois plus cher.

About this item

Description
4 Inch Wet Diamond Core Drill Bit
Made of premium carbon steel with diamond-grit teeth, this core drill bit maintains sharpness while cutting and grinding hard materials, delivering excellent wear resistance and long-lasting durability.
Our diamond wet coring bit enables fast cutting in wet mode, which provides cooling and lubrication to reduce wear, extending drill life, and minimizing dust for cleaner operation.
Crafted with high-precision welding for excellent wear resistance and high-temperature stability, this concrete core drill bit keeps diamond teeth strong and secure under tough drilling conditions, minimizing tooth loss or detachment for long-lasting durability.
These core bits for concrete are simple to install and operate, even for beginners. Ensure the drill bit is straight and aligned with the hole wall during use for optimal performance and results.
The core bit ensures clean, precise holes in tough materials like red bricks, concrete, and foam blocks. Suitable for all your drilling needs in construction and renovation projects.
