One Bit to Rule Them All — Tough & Versatile
Absolutely brilliant drill bit! The hex shank gives it solid grip in impact and rotary drills, and the carbide tip handled brick, tile, and even concrete without faltering. I love that I can switch between materials without changing bits—huge time saver. Extremely functional and great value as you can reuse it many times It cuts cleanly at slow speeds (no wandering), and the spiral flutes do a great job clearing dust—drilling felt smooth and precise every time. Built tough too—I’ve used it repeatedly and it’s still sharp. Ideal for tackling a variety of DIY or home improvement jobs—always in my toolbox now. Highly recommended!

My new go to bit
These fisher bits are excellent. Great quality, sharp and durable. I mainly use them when fitting kitchens, but also for lots and general building jobs. These bits fit in the impactor so no need to have two separate drills on the go. I’m still using the 1st bit I purchased, but I have bought a few more recently because I’ve been so impressed with them.

A really good drill bit
Fantastic - cut through bathroom tiles in seconds, it didn’t need any water to aid drilling, accuracy was great and its durability was really good - I did 10 holes in 30 minutes and it still looks good as new. Excellent value for money.

Nice drill bit when used for various projects
Surprised how well this is made considering the price point , I haven’t used this on concrete or engineered bricks I use sds for that this drill bit managed a whole variety of other materials and so far it’s still working fine I guess if your drilling hard surfaces a lot it will blunt but I tend not to use this with hammer function very often I would say it’s a decent drill bit

Great all rounder bit used primarily for brick, block, concrete
High quality bits equal to bosch ones, which last a long time. Great all rounder bit used primarily for brick, block, concrete

Idéal pour le béton et passe bien dans la pierre. Etonnant, très bon dans l'aluminium aussi. Semble inusable.
