Diablo SnapLock Plus Hole Saw System: A Faster Way to Swap Sizes Mid-Job

Introduction

Hole saws have always had one annoying friction point: swapping sizes means fumbling with arbors, threads, and adapters while standing on a ladder with an armful of gear. The Diablo SnapLock Plus hole saw system attacks that problem directly. First introduced at World of Concrete 2024, the system builds on the brand’s existing hex-style hole saws but adds a snap-lock mandrel that lets you click blades in and out in seconds.

Who This Product Is For

If you work in HVAC, plumbing, or construction and spend your days running pipe, conduit, or tubing, this system is built around your workflow. The range covers a wide spread of sizes, including 1-3/8 inch, 1-3/4 inch, 3 inch, and 3-5/8 inch cups, and the blades are rated for metal, wood, and wood with embedded screws or nails.

Main Strengths

The core idea is a single mandrel. Slide a hole saw onto the arbor, it clicks in, and you are ready to drill. Moving from a 7/8 inch cup to a 2 inch or even a 6 inch cup takes seconds, with no adapters to remove and swap back and forth. Because the lock mechanism is built into the Diablo blades themselves, you do not need to change adapters between sizes.

Unlike the earlier hex-style setups, this system comes with its own SDS-compatible arbor with a quarter-inch hex input, giving it a heavy-duty feel. Paring it with an SDS rotary hammer such as a Bosch Bulldog lets you run in drill mode with more oombehind big holes, and the arbor is designed to handle that class of tool.

The pilot bits are notably longer than most on the market, so you can punch through thicker material without flipping the workpiece to finish from the other side. That matters when a barrier sits behind the board and a second pass is not an option.

Plug removal is another strong point. Slots on both sides of the cup let you pop the core out sideways instead of digging at it with a screwdriver. Cores came out smoothly in testing, some literally falling out on their own, and even a firmly wedged plug can be pushed out from the back. Diablo claims these blades last up to 50 times longer than the blades you may be using now, and the brand’s hole saw blades have a reputation for holding up well even under heavy use and abuse.

Things to Consider Before Buying

The SDS setup is worth thinking about. A rotary hammer gives you more torque, but if your drill driver lacks a twist-off safety clutch, aggressive hole saw work can twist your wrist hard when the bit binds. That is exactly why the SDS option exists, though it is worth noting an SDS rotary hammer can feel a bit slower and less powerful for pure hole drilling than a dedicated hole saw tool.

If you already own other brands’ hole saws, the system includes adapters, a 5/8 inch adapter for larger arbor holes and a smaller one for compact mandrels, so you can still mount competing cups. And if you do not own an SDS tool at all, the system can also run on a standard drill, which keeps the entry barrier low.

Buying Advice

Buy the full system if you regularly change hole sizes on the same job; the snap-lock workflow is where the real time savings live. If you already own a healthy collection of other-brand hole saws, the included adapters let you ease into the ecosystem rather than replacing everything at once. Pair it with an SDS rotary hammer for big-diameter work in thick material, or a standard drill for lighter duty.

Conclusion

The Diablo SnapLock Plus system earns its spot in a trade bag by removing the small frictions that add up over a long day: fast blade swaps, longer pilot bits for one-pass holes, easy plug ejection, and an arbor tough enough for rotary hammers. For anyone cutting holes in pipe runs, studs, or sheet material all week, it is a genuinely practical upgrade.
