Drill America Carbide Tipped Masonry Drill Bit Set (5-Piece)

Designed for drilling in brick, concrete and sandstone. Carbide tips brazed to tough steel bodies and are larger than the nominal drill size to provide clearance for installation of anchor screws, expansion shields and toggle bolts. Designed for use in portable electric drills. They are the best i’ve ever had love the length on them too to go thru a cinder block…..

This is a good starter set, for someone who only needs to drill a few holes in masonry materials. The carbide tips seem to be well brazed to the steel shanks. However, while 4 of the 5 bits in my set came with “sharp” edges on the tips, the 3/8″ size bit clearly has a “dull” tip. It looks like the factory didn’t cut enough carbide, and the tip of that particular bit looks noticeably blunt. Hammer drills do not necessarily need “sharp” cutting edges to drill holes in masonry, so the bit might work “OK” with your drill in hammering mode. Without hammering – it’s just going to go around and around… When I need that 3/8″ bit, I am going to regrind the tip and I am sure it will work fine, but I realize that not everyone has a grinder.

After burning the tips of my old masonry drill bits last weekend installing an exterior security light fixture in a brick wall, I needed to replace my bits. Home Depot has a 5 pieces Carbide Tipped Masonry Drill Bit Set from Drill America. This set of 5 range of sizes listed: 3/16 in. x 6 in., 1/4 in. x 6 in., 5/16 in. x 6 in., 3/8 in. x 6 in. and 1/2 in. x 6 in. They come in a plastic pouch with separate pockets for each bit. This is an Feature that gives me an Advantage of not looking through a bunch of bits in the bottom of the toolbox, so I find the right bit easier. Now these masonry bits have carbide-tips and this Feature gives me an Advantage of longer wear resistance and the shank of steel for toughness. A black oxide treatment adds the Feature of lubrication and holds the coolant near the cutting edge giving that Advantage when drilling. I am looking forward to using this Drill America in the future. I hope that I helped you to choose as I did from Home Depot the Drill America 5 piece Masonry Drill Bit Set.

I used the 3/16″ bit from the Carbide Tipped Masonry Drill Bit Set (5-Piece). I used it in concrete, and I used it in brick. The bit cuts about as well as the top shelf Bosch bit. Using a Milwaukee M18 drill, it didn’t cut any faster or slower than the Bosch. Using the Milwaukee’s hammer drill function, the Drill America rapidly dug into both the concrete and the brick as well as a Bosch. The black oxide coating wore off after a few holes, but the carbide hung tough. The only problem is that the butt end of the drill mushroomed with the hammer drill usage. I suppose you could grind off the mushroom, but I didn’t bother since it worked well in the Milwaukee. Drill America says the carbide tips “are larger than the nominal drill size,” but it didn’t seem to make any difference. The Tapcon 1/4″ screws worked great in the holes I drilled. I guess it’s a really good bit as long as you don’t use a hammer drill.

I bought these to bolt some anchors into a concrete stair landing pad. I felt they cut very fast and after 20 holes cut, I didn’t notice any wear. For a starter set, you cannot beat this value. I do not use these often and it doesn’t make sense to buy the expensive drill bits. I have used the Bosch before, I can’t say I noticed a difference. They both cut about the same.

This 5-piece set of 6-inch drill bits is a convenient way to acquire common size masonry drill bits. I’ve only used one of them (5/16″) and it performed very well and held up well on brick with a standard drill. I believe it would perform equally well but faster with a hammer drill. I admit I don’t have a great need for 6″ masonry bits””most of my DIY masonry applications are only 2″ at most. If your needs are for deeper holes in masonry, you should consider this set.

A fair price.

Heavy duty masonry drill set (5 pc) for making holes in concrete, brick, sandstone etc. Carbide tipped means a longer duty life and wider than normal flutes aid in removing debris from the drilled hole (run drill in reverse to clean out hole.) These are “percussion bits” (percussion is just another word for hammer) intended for use in hammer drills although the description merely says “For Use In Portable Electric Drills.” There are various drill bit types that are specifically labelled “Not For Hammer Drill Use” because they might fail or shatter possibly causing injury but THESE are designed for hammer drills (I actually called the manufacturer and verified this and was told they would reword their description to make this clearer) So, if your drill bits are becoming damaged or “mushroomed” it probably means you are pushing too hard when using them which can seriously overheat them. Ease up some and/or use some kind of lubricant and you should be good to go.

A great collection of 5 cement carbide tip drills, from 1/8″ to 1/2″. I use a lot of these drills, drilling cement and some are cheap but these are not. These drills are well made and have already used one this weekend for drilling a gate rod stop in cement. No problem in drilling and clearing the hole. Very strong and sturdy with multiple uses. I’m hoping they last much longer than my others. Time will tell the complete story. Recommend.
