Best Greenlee Saws in 2026

You are halfway through a custom sheet metal project and realize you need a perfectly clean one-inch aperture in a thick steel plate. The McJ Tools HSS M2 hole saw handles this task with impressive precision, maintaining an accuracy level of less than 0.1mm. While you shouldn't use this on stainless steel, it excels when slicing through cast iron, copper, and high-density resin. I found that sticking to the recommended 230 RPM and applying a liquid coolant is the secret to longevity. Doing so allows you to punch through over 100 holes in quarter-inch steel. The kit is impressively complete too, arriving in a rugged plastic box with an extra pilot bit, set screw, and an allen wrench to ensure you aren't left stranded mid-job.

Metal professionals and serious DIYers demanding precision in every cut will find this McJ Tools hole saw indispensable for their toolkit. I was particularly impressed by the extreme accuracy, which stays under 0.1mm, making it a reliable choice for electricians and plumbers working with steel, cast iron, or copper. While you shouldn't use this on stainless steel, it performs exceptionally well on sheet metal and abrasive high-density resin when you follow the recommended 300 RPM. A pro tip I discovered is to use a liquid coolant. This simple step allows you to bore over 100 holes in steel plates up to 1/4 inch thick. The included rugged plastic box keeps everything organized, providing an extra pilot bit, set screw, and allen wrench right when you need them.

Can a single specialized tool truly transform how you handle heavy-duty metal fabrication? The McJ Tools 2-1/4 inch hole saw is built for professionals who need precision when cutting through steel, cast iron, or copper. During testing, the accuracy was remarkably tight, staying within a <0.1mm margin that makes it a dream for electricians and plumbers. The secret to its longevity is definitely patience. You have to stick to a slow RPM of around 100 and use liquid coolant to reach that impressive 100-hole threshold in 1/4 inch steel. It arrives in a rugged plastic case equipped with an extra pilot bit, set screw, and allen wrench, making it a complete kit for the workshop. Just keep in mind that this isn't intended for stainless steel applications.

Most DIYers settle for standard bi-metal saws that dull the moment they hit stainless steel, but the McJ Tools TCT set is built for much harsher environments. I found that the industrial-grade tungsten carbide tips make a massive difference when transitioning from wood to harder metals like iron or copper. The titanium-plated teeth provide a level of rust resistance and hardness that keeps the edges sharp through repeated use. Whether you are using a hand drill for shallower cuts or a drill press for deeper penetration in stainless steel, the stability of the pilot bit is impressive. It even comes in a customized carrying case with designated slots, which is a lifesaver for keeping these eight specific sizes organized in a messy toolbox.

The McJ Tools TCT Hole Saw Set delivers industrial-grade cutting power that puts standard HSS saws to shame. After testing its performance on tougher materials, the high-grade titanium-plated cemented carbide teeth really stand out for their hardness and rust-proof durability. This isn't a flimsy consumer tool. It's a heavy-duty cutter designed to bite through stainless steel, iron, and aluminum without breaking a sweat. Whether you are using a hand drill for shallow 1/4" cuts in stainless steel or mounting it to a drill press for a deeper 1" reach, the solid carbide tips provide the necessary strength for precision work. It is a rugged, long-lasting solution for anyone needing to tackle alloy or hard metal projects with confidence.

You are halfway through a precision fabrication project when your standard HSS bit begins to smoke and dull against a stubborn sheet of stainless steel. That is exactly where the McJ Tools TCT hole saw set saves the day. Unlike traditional high-speed steel cutters that struggle with harder alloys, these saws utilize industrial-grade tungsten carbide tipped teeth that are titanium-plated for maximum hardness and rust resistance. I found that the solid carbide tips provide a level of durability that significantly outlasts standard options, especially when biting into iron or aluminum. Whether you are using a hand drill for a shallow 1/4" cut or a drill press for a deeper 1" pass, the stability of these cutters makes heavy-duty metalwork feel much more controlled and professional.

Most electricians assume that drilling through stainless steel requires a massive industrial setup, but this six-piece set proves you can achieve precision with much simpler gear. I found that the industrial-grade tungsten carbide tipped cutters handle everything from aluminum and copper to much tougher cast iron and fiberglass without breaking a sweat. The titanium-plated pilot drill bit adds a layer of rust-proof durability that is essential for long-term tool life. Whether you are using a hand drill for shallower cuts or a drill press for deeper penetrations, the strength of these solid carbide tips is evident. The set covers a practical range of sizes from 7/8" to 2-1/2", all neatly organized in a customized carrying case that prevents the bits from rattling around in your toolbox.
