Best Neiko Drill Bits in 2026

The Neiko 10173A Step Drill Bit Set delivers incredible versatility through its massive range of 50 total step sizes. I was particularly impressed by how the split point tip prevents that annoying wandering when you first touch the metal, keeping your bore lines perfectly centered. The industrial high-speed steel is reinforced with a titanium nitride coating, which makes a noticeable difference when punching through tougher materials like stainless steel or copper.
