What Customers Are Saying
Customers are divided on this drill bit. Most praise its sharpness, durability, and ability to cut cleanly through dense wood like treated timber and railroad ties, noting it maintains straight holes and outperforms competing brands. Many highlight solid construction and appreciate the included plastic case. However, a substantial group reports catastrophic failures including bending, breaking, or getting stuck after just one to three holes, with some describing it as faulty or worthless. Despite these quality control concerns, most customers who had positive experiences consider it worth the investment.

Nice sharp bit that doesn't flex and wander
Would RecommendBit cuts well and is stout. I had picked up a different brand and that bit was very flimsy. This Irwin is solid, nice thick web and it doesn't flex, which means it is much easier to get straight holes that don't wander.
