What Customers Are Saying

The Stinger drill bits have received mixed reviews. Many customers found the bits to be durable and effective at drilling through tough materials like steel and metal. They praised the bits' sharpness and ability to create clean holes. However, a significant number of customers reported issues with the bits, stating they were brittle and prone to snapping or breaking, even when drilling basic materials. Some felt the bits were overpriced and did not live up to claims of being suitable for "extreme metal drilling."

These are garbage

Would Not Recommend

I’m not a professional and I have not used any of these drill bits more than maybe half a dozen times. Most of them are probably never been used and yet I can’t get them to drill anything. Finally, I went to ChatGPT and asked what I needed to have a reliable drillbit and they recommended either a.m. 35 cobalt or a M 42 cobalt drillbit and to only buy from something something reliable like Milwaukee or Bosch, DeWalt, Irwin, Drill America, Drill Hog I ended up buying Milwaukee m42 cobalt bits.

The only thing fast is how quickly it dulls

I bought this to drill into 3/16" steel posts. It took a ton of pressure on the drill to get it to cut the first 8 holes, and each one was slower than the last. Then it simply stopped cutting at all. I switched to a Milwaukee titanium bit I thought was too ordinary for the job. It sliced through the steel in seconds with no dropoff in speed through the final six holes. The Stinger ended up being a waste of money.
