Description of 🧱 Cinderblock Concrete Masonry Material by COMOWARE

💪MULTI-MASONRY DRILL BITS: This set is ideal for a variety of surfaces and materials. You can quickly penetrate through masonry, wood, plastic, cinder block, glass, concrete, ceramic, and tile brick, to name a few. 💪DURABLE INDUSTRIAL GRADE CARBIDE: Carbide drill bits are ideal for any masonry job as they are sharper than other tools. Such tools also remain sharp for a long time, reducing the amount of time spent on maintenance. Aside from the carbide tip, the whole bit is plated in chrome. Such a plating reduces corrosion and provides the bit with industrial strength. 💪SPECIAL TIP DESIGN: A tungsten carbide material hardens the tips. Such a combination reinforces the head against cracking and in turn, makes the pieces more robust. This helps to prolong the life of the bits compared other alternatives in the market. A spear-pointed tip design gives this product greater precision and piercing power. This feature allows the bit to penetrate trough sensitive surface like glass. 💪UNIQUE U-TYPE SLOT DESIGN: The bits are ideally suited to general-purpose, bench, and electric drilling. Each drill has a unique U-type slot design. This design allows for fast penetrating and evacuation of debris as you work. 💪INCLUDES THE FOLLOWING SIZES: These bits satisfy your demand for versatility with 10 drill bits in every pack. The set has six different sizes that run from 1/8" (3" LENGTH - 2 INCLUDED) to 1/2" (6" LENGTH). | 1/8", 1/4", 1/4", 5/16”, 3/8", 1/2".

Count Before You Buy

My fault is that I didn't understand exactly what I needed and was in a rush to buy something to get next day delivery. Dimensions are clearly stated in the listing. BUT be aware that there is a big gap between 5/16" and 1/2", especially in the fastener world. My anchors were #10, which is probably 3/8" or maybe 7/16", so I had a choice of undersized hole or oversized hole. If you're lucky you're on mortar and have room to widen the hole by sawing 5/16" sprockets or 2 sprockets because instead…

Ordinary bits for masonry with carbide tips.

Today I finally learned how to use it to drill holes in ground mortar. When I was done, the carbide tip still showed sharpening marks and the cutting edge was still sharp, so I decided to experiment. I drilled a hole in a beer bottle with a cordless drill in one hand while holding the bottle on the table with the other. I got a relatively clean hole and didn't crack the bottle. The drill is still sharp. I am happy. The reason I took off a star is because they advertised wood drilling! I know…

Not the best choice for concrete or plaster

I bought these with two projects in mind. First, I drilled 1/8" pilot holes in the plaster of my house for some wire clamps. Second, drilling holes in the cinder block for small anchors. The two attached pictures show a new drill bit and the same drill bit after drilling a hole in the plaster . This is the second 1/8" I've used. After the same thing happened to the first one I wanted to see if it was a manufacturing defect or if the bits were that brittle. Turns out they were so brittle. I was…
