KnKut 60-Piece Short Stubby Drill Bit Set (Sizes 1-60) - Premium HSS Metal Drill Bits for Precision Drilling in Tight Spaces, DIY Projects & Metalworking

This is without a doubt one of the few top tier drill bit sets. KNKUT drill bits are manufactured with the tightest, toughest and most accurate quality control processes.All KNKUT drill bits are salt nitride treated during manufacturing. a process that actually penetrates the drill bit metal surfaces giving KnKut Drills the hardness needed to drill through extremely tough materials such as stainless steel and titanium alloy. Premium grade KnKut Drills are manufactured from a high grade M-7 Molybdenum high speed steel.As a mechanic for over 45 years, I have worked on just about every US Naval surface vessel. Top to bottom, side to side, I've worked on almost all type of equipment. And that includes different types of Pumps, Valves Heat Exchangers ... even main plant equipment like 1200 PSI Main Boilers, Multiple Stage Superchargers. You name it and I've probably worked on it and all I will say is that KNKUT Drill Bits are the only type of drill bits I would prefer in my tool boxes.Only after retirement and working on Oil Refinery equipment did I get to hands on prove their best was no match for KNKUT Drill Bits. Afterwards, the mechanics division chief changed what they would buy from then and into the future. Just tough as heck and always reliable.That simple change increased running up-time, decreased machinery down time, decreased quarterly and annual expenditures. Now that is what KNKUT is all about. Making your work easier with less associated costs.
