Best Cmt Hole Saws in 2026

The EZARC Carbide Hole Saw delivers an incredible lifespan that puts standard bi-metal saws to shame. After testing it on tough materials, the standout is clearly the carbide teeth, which are rated to cut through stainless steel for over 500 holes. This isn't just for soft metals either. It handles iron, copper, brass, and mild steel up to 3/16 inches thick with ease. I love that it comes as a complete kit with the pilot bit, spring, and wrench included, so you can start drilling immediately without a trip to the hardware store. The spring-loaded pilot bit makes the whole process smoother by ensuring clean plug ejection every single time. It is a rugged, efficient tool for anyone tackling heavy-duty sheet metal projects.

The biting edge of this 155mm cutter feels incredibly substantial the moment you line it up against a workpiece. Built from a combination of HSS carbon steel and bi-metal steel, this tool hits a hardness of 65HRC, which gives it a serious edge when tackling wood, drywall, or fiberboard. I found that the spindle structure stays remarkably stable during operation, preventing that annoying wobble or slipping often seen with cheaper alternatives. While it delivers a clean, symmetrical circle, you have to resist the urge to force it. Keeping a low speed and letting the serrated teeth do the work is the secret to that smooth finish. It is a reliable choice for everything from installing light fixtures to routing drainage pipes.

Most DIYers settle for cheap, flimsy cutters that wobble or snag, but the Laiwei 150mm Bi-Metal Hole Saw provides a level of stability that makes large-diameter drilling much less intimidating. I found the spindle structure remarkably firm, which eliminates that frustrating shaking often seen when trying to maintain a clean line. It handles wood, drywall, and thin metal sheets with surprising smoothness, and the unique design actually makes chip removal a breeze rather than a constant struggle. Since it is constructed from durable 42# carbon steel bimetal, the sawtooth teeth feel like they are built to endure repeated use without falling off. It is a reliable, efficient tool for anyone needing clean 6-inch holes without the typical headache of overheating or jamming.

Most people assume a large 168mm hole saw will struggle with heat buildup, but this TIDEWAY model uses specialized side holes to solve that exact problem. By facilitating rapid chip evacuation, the tool prevents the clogging that usually ruins a clean cut. I found the combination of high-speed steel and M42 carbon steel makes a massive difference when transitioning from soft gypsum board to tougher thin metal sheets.

The 25mm cutting depth covers most standard household projects, from installing desk grommets to furniture modifications. I particularly liked how the customized storage case keeps the thirteen saws, two mandrels, and essential hardware organized and easy to grab mid-project. While you shouldn't expect these to tackle heavy-duty metal, they are a reliable, oil-resistant solution for softwoods and plastic plates that makes professional-looking hole cutting much more accessible.

Contractors tackling heavy-duty masonry and dense building materials need the MaxTool 5-inch TCT hole saw to stop wasting time on dull, standard blades. I found that the high-hardness carbide teeth are the real standout here, maintaining their edge even when grinding through abrasive limestone or brick. The 2.25-inch cutting depth is a massive advantage for thick, layered materials, allowing you to finish a job in a single pass rather than struggling through multiple attempts. I also appreciated the wide gullet design and knock-out slots, which make ejecting the core much less of a headache. While you will need a carbide tip pilot drill for certain tough materials, the reduced vibration and smooth cutting load make it much easier to handle with your electric power tools.
