Review on 🔧 Enhance Precision with Klein Tools KTSB15 Double Fluted: A Reliable Power Tool Accessory by Paul Rosemark

I bought this step attachment for my husband for his birthday after hearing him talk about how he needed this attachment for his work. He didn't use it for weeks until a co-worker asked if he had a step drill to drill a 7/8 hole in the side of the electrical box. Excitedly, he offered his colleague his new small nozzle. The drill broke the shank right before his eyes when the hole was half-drilled. I don't know if it was a bad stair crown or just a bad small product, although my husband was very disappointed that he didn't even have time to drill a hole with his new step drill bit before it broke.
