MPN: DHS0781
Minimum order quantity is .
Diablo DHS0781 25/32" Bi-Metal Hole Saw is engineered to redefine speed, depth, and reliability in hole drilling. Designed for professional trade work, this 25/32" diameter bi-metal hole saw combines aggressive cutting geometry with a robust system that makes mounting faster and easier than ever.
Key features that set this hole saw apart:
- Bi-metal construction for versatility and durability — a hardened tooth steel welded to a flexible backing delivers long-lasting performance across metal, wood, and compatible plastics, helping you tackle a variety of jobs with one tool.
- Radical tooth design for faster cuts — engineered geometry reduces drag, improves chip evacuation, and delivers cleaner holes in less time, so you can move from task to task without pause.
- Ultimate cutting length for deeper holes — the extended cutting edge is optimized to bore deeper holes in a single pass, reducing the need for multiple passes and re-drilling.
- Tool-free plug ejection — effortlessly clear the waste plug without tools, keeping the workflow smooth and uninterrupted.
- Intuitive hole saw system and mandrel design — streamlined attachment simplifies mounting, ensures secure seating, and minimizes setup time on the jobsite.
What problems it solves
When you’re shaping electrical, plumbing, or HVAC installations, clean, precise holes matter. The DHS0781 delivers fast, accurate cuts with less heat and burrs, reducing rework and material waste. The ability to bore deeper holes in a single pass is a real time-saver on thick stock or when routing through metal plates and wood blocks.
Ideal for
- Electricians drilling through metal boxes, studs, and panels
- Plumbers preparing openings in joists, studs, and sheet metal
- HVAC technicians creating larger bore holes in ductwork or mounting surfaces
- Woodworkers and general contractors needing reliable, straight holes with minimal effort
Why choose Diablo DHS0781 over alternatives
Unlike standard hole saws, this Diablo design emphasizes a fast attachment system, deeper single-pass cutting capability, and plug-ejection convenience. The combination of bi-metal teeth with a robust backing delivers dependable performance across varied materials, while the tooth geometry and cutting length are optimized to reduce heat buildup and deliver smoother, cleaner holes from start to finish.
Practical tips and best practices
- Use a compatible mandrel for best alignment and seating. The system is designed for quick, tool-free setup and secure mounting.
- Start with a light pilot or center mark to guide the saw and prevent wandering, especially on metal surfaces.
- Feed steadily and avoid forcing the cut. Let the teeth do the work to minimize heat and prolong tooth life.
- When drilling metal, consider a light cutting fluid or barrier spray to reduce heat and extend tool life.
- Clear the plug immediately with the tool-free eject mechanism to maintain cutting speed and reduce downtime.
For professional results on a range of materials, the Diablo DHS0781 25/32" Bi-Metal Hole Saw pairs seamlessly with Diablo’s hole saw system and mandrel line. It’s the reliable, high-performance choice for fast, accurate holes you can count on job after job.
