The is by far the best drill bit I have ever used. I needed to drill a hole in a stainless steel sink. I was installing a filtered water faucet. I had heard there were hardening issues when drilling stainless steel so I was nervous doing it. I watched a few you tube videos and most showed using a step drill bit. After reading the reviews on the Klein Tools KTSB14 Step Drill Bit I decided to purchase one. To keep the stainless steel cool, I placed ice cubes around the spot where I was going to drill the hole. I dipped the Klein Tools KTSB14 Step Drill Bit in a small bowl of water with ice cubes to keep it cool. Drilling at a very SLOW speed and applying a lot of pressure I started to drill the hole. At first it only made a dimple. I again dipped the bit into the iced water and then started drilling again but at a LITTLE faster speed. Once the bit started cutting there was no stopping. It cut like a hot knife in butter. I dipped the bit into the iced water for a third time and started drilling some more. In seconds I was done. The hole was perfectly cut thanks to the markings on the side of the bit and the bit was cold to the touch thanks to the iced water and slow speed I drilled at. It took longer to write this review than it did drilling the hole.
