Review on 🧱 High-Quality Muzerdo Concrete Shank Cement Bricks for Enhanced Durability by Robert Prix

DRILLING: These drill bits make excellent drill bits. They're nothing special, but they're a little cheaper than branded bits of this size. I haven't had any of the carbide teeth fall off yet, so that's a good thing. Time will tell how well these beats hold up, but so far so good. I've drilled both concrete and granite - it works, but quite slowly. My main concern is the size of the shaft, which I have detailed below. I really wouldn't want to drill into concrete or granite anymore - instead I'd use softer materials with these bits (unless you plan on standing around with your drill all day). The pavilion is not that well designed. It simply screws in, allowing the bits to self-tighten as you use them. You will need to use a metal rod inserted into the holes on the side of the bits to have enough strength to unscrew them. Also, you cannot tighten or loosen a set screw when a hole saw is attached. The hex head sticks to the hole saw. To tighten or loosen the set screw, the hole saw must be unscrewed. You either had to place it a little further down the shaft or use an Allen screw instead. TAILS: The smaller bits in this set fit the SDS Plus shank. However, larger bits should actually have an SDS-Max shank. I don't know of any SDS-Plus drill bits that are strong enough to work well with a 5" hole saw. When it comes to SDS Plus shanks, I usually think of more portable battery powered drills. my massive Bosch SDS-Max drill that will handle anything I throw at it. For smaller jobs I usually use the 20V Dewalt SDS-Plus drill/driver. Although it's battery powered, it doesn't mess around - I'm usually surprised at how well it did most of the tasks I gave it. I worked on this for some time with this 125mm drill and discharged the entire 4Ah battery - I only drilled a few millimeters into the granite block I was testing on. Drilling to a greater depth with this larger bit would have been a huge waste of time and battery. Given the wide range of drill bit sizes included in this kit, I think they really should include SDS-Plus and SDS-Max shanks. The threads on the hole saws appear to be heavy enough to accept an SDS-Max shank. without problems. I know I can buy an SDS Max to SDS Plus adapter to use these drills with my big drill, but these adapters tend to take some of the impact energy out of the drill, and the big SDS Max drill may bend/bend . damage the SDS Plus shaft (there is a reason the SDS Max shaft is much thicker). CASE: The supplied case is fine. It's meant to look like a high-end case, but it's nothing special. The corners are made from extruded aluminium, while the panels are made from thin plastic painted to look like aluminium. The panels to me arrived broken in transit (or from the factory - there was no apparent damage to the shipping packaging). The foam cut outs for the bits inside the case are ok and hold everything securely. Foam tends to trap dirt, dust and moisture. All of that contamination is to be expected when using stone nozzles like this and instead I'd prefer a hard case with no foam (even a good blown case would be preferable to me as I don't usually like blown cases). ).
