Milwaukee Electric Tool 49-56-0117 Bi-Metal Hole Saw, 2″ – Professional Review

When we first unboxed the Milwaukee 49-56-0117 2-inch bi-metal hole saw, we knew we were holding a tool built for serious work. After putting it through its paces on various materials and job sites, we can confidently say this isn’t just another hole saw—it’s a reliable workhorse that delivers consistent performance when you need it most.

Why the Milwaukee 2-Inch Hole Saw Stands Out

During our hands-on testing, we immediately noticed the superior build quality that Milwaukee is renowned for. The bi-metal construction combines high-speed steel teeth with a durable alloy backing, creating a hole saw that handles both the impact of tough materials and the heat generated during cutting. We’ve used cheaper alternatives before, and the difference is immediately apparent—this tool simply feels more substantial and engineered for longevity.

The 2-inch diameter proved to be one of the most versatile sizes in our collection. Whether we were installing door hardware, running electrical conduit, or creating ventilation openings, this size handled the majority of our residential and light commercial applications without breaking a sweat.

Performance That Speaks for Itself

Cutting Through Wood Like Butter

Our first test involved cutting through various wood materials—from standard dimensional lumber to hardwoods and even laminated surfaces. The Milwaukee hole saw delivered clean, precise cuts every time. The sharp, variable-tooth design grabbed the material quickly without the excessive chattering we’ve experienced with lesser-quality hole saws. Even when working with thicker stock like 2×6 studs, the saw maintained its cutting speed without bogging down our drill.

Metal Cutting Capability

Where this hole saw truly impressed us was during metal cutting applications. We tested it on 16-gauge steel, aluminum sheeting, and even some stainless steel fixtures. The bi-metal teeth stayed sharp throughout our testing, and the tooth geometry efficiently cleared chips, preventing the binding that often plagues metal cutting operations. We did use cutting oil for the stainless steel work, which we’d recommend for optimal performance and tool life.

Durability You Can Count On

After dozens of cuts across multiple materials, we inspected the teeth closely under magnification. The wear was minimal—far less than comparable hole saws we’ve tested in the past. The electron beam welding that bonds the teeth to the backing cup appears to be exceptionally robust. We didn’t experience any tooth loss or significant dulling, even after our most demanding tests.

The thickness of the backing cup also deserves mention. It’s rigid enough to prevent warping during heavy use, which helps maintain the circular cut quality over the tool’s lifespan. We’ve had cheaper hole saws develop slight oval deformities after repeated use, but the Milwaukee maintained its perfect round shape throughout our evaluation period.

What Real Users Are Saying

Milwaukee 2 Inch Bi-Metal Hole Saw for Wood Metal Cutting has garnered significant attention from both professional tradespeople and DIY enthusiasts. After analyzing hundreds of customer reviews, we found that our experience aligned closely with the broader user base.

Professional electricians consistently praise the saw’s ability to create clean holes in metal junction boxes and panels without excessive burr formation. Several HVAC technicians mentioned using this exact size for ductwork modifications and venting applications, noting that it outlasts competitor products by a considerable margin.

Woodworkers appreciate the clean entry and exit holes, particularly when working with finished materials like cabinet panels or doors. Multiple users confirmed our finding that the saw doesn’t tear or splinter wood fibers excessively, even without a backing board—though using one certainly produces even cleaner results.

Some customers noted that the saw doesn’t come with a pilot bit or arbor, which is worth mentioning. Milwaukee sells these separately, allowing professionals to choose the arbor system that best fits their existing tool collection. While this might seem inconvenient initially, it actually provides flexibility and prevents paying for components you might not need.

A few users mentioned that the depth of cut (approximately 1-5/8 inches) was insufficient for certain specialized applications, but this is standard for hole saws of this construction and wasn’t a limitation in our typical use cases.

The Technical Advantages We Noticed

Tooth Design and Geometry

The variable pitch tooth design is engineered to reduce vibration and noise during cutting—something we definitely noticed during extended use. This design also helps prevent tooth strippage and increases cutting speed by reducing friction. When we compared it side-by-side with a constant-pitch hole saw, the Milwaukee was noticeably smoother and quieter.

Heat Resistance

Bi-metal construction isn’t just marketing speak—it genuinely matters during demanding applications. The high-speed steel cutting edge maintains hardness even when cutting generates significant heat, while the flexible backing absorbs shock and resists cracking. During our metal cutting tests, we deliberately pushed the tool hard to generate heat, and it continued performing without any signs of tooth annealing or backing deformation.

Practical Applications We Tested

Throughout our evaluation, we used the Milwaukee 2-inch hole saw for:

**Electrical Work**: Creating knockouts for outlets, switches, and conduit runs in both wood studs and metal studs. The clean cuts meant less time filing burrs and easier wire pulling.

**Plumbing Applications**: Drilling holes for pipe passage through floor joists and wall plates. The size accommodates 1-1/2 inch pipe with adequate clearance.

**Door Hardware Installation**: Cutting holes for deadbolts and passage sets. The precision ensured proper alignment and professional-looking results.

**HVAC Modifications**: Creating vent openings in ductwork and wall penetrations for refrigerant lines.

**General Carpentry**: Various woodworking projects requiring precise circular cuts for dowels, decorative elements, and cable management.

Tips for Getting the Best Results

Based on our extensive testing, here are some recommendations to maximize performance and tool life:

**Start Slowly**: When beginning a cut, run your drill at lower speeds until the teeth fully engage the material. This prevents walking and ensures a centered hole.

**Use Pilot Pressure**: Let the pilot bit guide the cut before applying significant pressure to the saw teeth. This improves accuracy dramatically.

**Clear Chips Frequently**: Especially when cutting metal or making deep cuts, periodically withdraw the saw to clear accumulated chips. This prevents overheating and maintains cutting efficiency.

**Appropriate Speed**: For wood, we found medium-to-high drill speeds worked best. For metal, slower speeds with steady pressure and cutting fluid produced optimal results.

**Secure Your Workpiece**: This seems obvious, but properly clamping material prevents binding and potential kickback, which protects both you and the tool.

How It Compares to the Competition

We’ve tested hole saws from virtually every major manufacturer, and the Milwaukee 49-56-0117 consistently ranks at the top for this size range. Compared to economy brands, the difference in cut quality, durability, and tooth longevity is substantial—often outlasting cheaper options by 5-10 times in our experience.

When compared to other premium brands like Lenox and Bosch, the Milwaukee holds its own admirably. The cutting performance is essentially equivalent, with slight variations based on specific materials. Where Milwaukee often has an edge is in availability and pricing, particularly when purchased as part of their larger hole saw sets.
