What Customers Are Saying

The product features a tri-flute design that allows for efficient and quick drilling through various types of wood. Many users praise its speed and ability to create clean, straight holes. However, some report issues with durability, especially with the smaller 1/4-inch shanks, noting the bits can dull or break prematurely. There are also concerns about potential splintering or damage on the backside of the wood due to the aggressive cutting action. Overall, the product seems suitable for many woodworking tasks, but users should pair it with a powerful drill to get the best results, and the 3/8-inch shank versions are preferred for more demanding applications.

Worked great for me.

Would Recommend

I used my Milwaukee battery 18 volt 1/2 inch Hammer Drill used drill only in control mode 1 not high speed also used the hand hold bar installed, but it was hardly needed as little twisting occured. Irwin speedbor cut through a old hard 2x4 with no splinters on exit as seen in my pictures it cut quickly with just a firm pushing with no binding of the tool.

So far, so good 😊

Would Recommend

I needed this for drilling through framing in wall to run low voltage wiring. My first use was with DeWalt DCD805B to drill through two stacked framing 2x4s. Like butter. I can't speak to durability, I will rarely need it, but worked great for me out of the box.

If you want to work smarter, not harder, get one

Would Recommend

I am running power in my shed and I was using a spade bit, which wasn't working all that well. A friend suggested I use a auger bit. I am glad I did. This thing cuts through 2x4s like butter. What a great investment.

Great for drilling stumps

Would Recommend

I drilled 8 holes in stumps. It is almost too good. It bites and really digs in fast. Just keep pulling out to clean the hole. Still sharp. Some larger stumps may need a longer bit versus this 6 inch bit.
