The same bits you use on hardened steel work on stainless. We have great news for anyone looking for the best drill bits for stainless steel. With a bit less cobalt in the steel blend, it just heats up a bit more quickly. The Irwin 29-piece Cobalt M-42 Metal Index Drill Bit Set performs very similarly to the M42 set. Irwin 29-piece Cobalt M-35 Metal Index Drill Bit Set The round case makes it simple to remove the exact bit you need. They also seem to hold an edge and stay sharp even after dozens of drilled holes. They make these bits with M42 cobalt steel so they drill really well without heating up quickly. The Drill America D/A29J-CO-PC includes 29 bits in a shatterproof round case. Some other great options include: Drill America D/A29J-CO-PC 29-pc Cobalt Set Pick up the Jobber Length Drill America D/A29J-CO-PC kit for just $106. It includes 29 bits in a shatterproof case. Use these bits when drilling tough, high tensile strength materials like stainless steel-or even titanium. Drill America also doesn’t grind down the shafts on its larger bits-so you get more rigidity, but you also need a 1/2-inch chuck to drive them. Because of how hard they are, you can drill up to 30% faster than you can with conventional M2 high-speed steel bits. They come manufactured to the National Aerospace standard 907. The jobber length bits work really well in cordless drills for onsite drilling. The bits feature the expected 135° split point, which gives you a nice, steady, and productive drilling speed. After testing with a multitude of materials, we selected their jobber bits as our best drill bits for hardened steel. Our best drill bits for hardened steel include the following:ĭrill America makes M42 cobalt bits that held up really well in drilling through anything we threw at them. Using a drill press is often the best way to get quality results. However, whatever differences there are between the outer look or chemical composition, both hardened steel and stainless steel are quite difficult to drill into. ![]() Because of rust and stain resistance, good luster, and low maintenance, it has many commercial uses including cookware, cutlery, home appliances, construction fasteners, and surgical instruments. Stainless steels are steel alloys consisting of at least 10.5% chromium and there are different grades. The best drill bits for metal could be designed for these hardened steel applications or they might be optimized for speed in softer carbon steels. Much of the steel materials that we see used in mechanical engineering, energy generation, and transportation are basically hardened steel. Hardened steels are durable and can be wear-resistant, corrosion-resistant, and abrasion-resistant. No matter if it’s a simple point of entry or a delicate material in need of absolute precision, these drill bits are shop-ready and available for every project imaginable.When we talk about drilling in hardened steel, we mean medium or high carbon steels typically made using a heat-treatment and tempering process. If you’re interested in working with laminate or glass, the optimized spurs of the double flute brad point wood twist drills insure fast and easy cutting of every fiber before the hole is drilled. Drills smooth and precise holes in soft woods, hard woods and laminates with 25-Percent less power required.ĭesigned for the professional trade and can be used in portable power drills and stationary boring machines. The FISCH Wave Cutter is a high performance, next generation Forstner Bit this set has been proven to drill 3 times the number of holes before needing to be re-sharpened! Its unique non-clogging design allows you to drill precise holes quickly without burning, while helping to increase the overall life of the bit. If you’re in the market for a brand new set of drill bits, consider a few available on Affinity.
