I purchased the 24PC, 5/32” x 7” with 1/4” SDS Plus Hex Rotary Hammer Drill Bits for working with concrete and would like to share my experience.Pros: 1. High-quality materials. The drill bits are made of durable steel, ensuring longevity and resistance to wear when drilling hard surfaces. 2. SDS Plus compatibility. They fit most SDS Plus rotary hammers seamlessly, making them highly versatile. 3. Effective performance. The bits penetrate concrete, brick, and stone quickly and accurately without excessive vibration. 4. Convenient size. The 7-inch length is great for deeper holes, and the 5/32” diameter is ideal for screws and anchors. 5. Economical set. With 24 pieces in the set, they last a long time even with frequent use.Overall, this is an excellent choice for those who work with concrete and brick frequently. The set offers great value for the price. Highly recommended for professionals and DIY enthusiasts alike!

Seems to drill fine but way too big to be classified as 5/32”

Very poor quality! They Break and become dull very fast, definitely not worth buying. Proof that you get what you pay for.

Okay, in about a week a little over 1,000 holes drilled. About 50 of those hit re-bar. Understand how we used these. A Bosch Bulldog hammer drill without the extra side bar; handle only. Usually drilled 70 to 100 holes without stopping. Drilling straight down into concrete floor in a business building. The first 30 bits failed real fast before I realized what the one guy was doing (I thought he was experienced Handy Man). He was putting his weight down onto the hammer drill and frequently had the drill in reverse! Once I noticed a few workers watching, waiting on, him, I went over and tapped him out. I have 20 years experience so I knew something was not right. I tried drilling the right way as I had taught him and it was not drilling. Checked and replaced brunt blunt tip one and then tried with a new bit. Same result. It was in reverse but too late. I took him off that duty and made sure everyone else understood that he is not to tough the drill again! So how should it work? I gave two other crew members (temp agency provided) demonstrated instructions. It is simple. Hold the Bosch Bulldog both hands gentle but firm. It is variable speed; pull trigger slowly and increase speed as the bit starts penetrating. THEN be sure to hold handle/trigger with one hand with zero pressure down but firm enough to prevent drill from spinning. Sometimes the bit will grab and you respond with just enough firm to prevent BUT ready to release if it grabs enough to twist your wrist...be safe. The key is just apply enough pressure for the bit to hammer/drill the hole. Adding slight pressure if the bit starts bouncing, just enough until it settles back into making the hole. We had to be alert to steel re-bar in the concrete floor because if you react quick, the bit will survive unharmed. More than a second on steel bar may burn the tip off when we are running it so hot. WE usually trigger full speed with assistant vacuum dust as drilling. The assistant them puts screw into hole firm before drill moves to next hole. That short time is barely enough to cool the bit and the bit will last a few holes to 30 holes depending on the timing and the driller touch. Why not drill speed at medium speed to keep heat down. I don't know but hope to remember next time. The point of this lengthy review is let the bit do the work by not pushing hard or leaning into it. AND once you drill using 1/4" and larger holes you may need only one bit for hundred holes. Every brand of 5/32" bit that I have used has performed just about the same regardless of price and manufacturer. I have over 25 years experience as an installer/foreman.

These are the best drill bits I’ve used, by far in the 35+ years of being in the construction industry. They are WAY more affordable and much more durable than the ones purchased from one of the big box stores. I HIGHLY recommend these drill bits.

Work great. Big box stores ones always break, these last a little longer and are way cheaper

Bought 12, still using the first one. $2.50ea., the alternative at HD is $7-$12.Pro user, if something doesn't work, it goes straight in the can. These work.
