Diablo Snap-Lock Plus 3 in. Carbide Tipped Hole Saw delivers professional-grade cutting efficiency with a compact cutting length of 2-3/8" and a sturdy 3/8" shank. Built for durability and precision, this hole saw is designed to tackle demanding tasks in wood, plastics, and light metals, delivering cleaner edges and longer wear life thanks to carbide-tipped teeth.
Part of the Snap-Lock Plus family, this 3" hole saw accepts quick-change mandrels for rapid bit swaps on the job site. The Quick-Change System is engineered to minimize downtime, letting you move between saws without removing the mandrel. Note: Arbor is not included; pair with a compatible Snap-Lock Plus mandrel for a seamless setup.
What makes it stand out
-
Carbide-tipped teeth extend cutting life and stay sharper longer than standard bi-metal designs, delivering consistently clean holes even after multiple passes.
-
3" diameter is ideal for standard electrical boxes, venting, plumbing passes, and conduit openings in cabinetry, walls, and furniture projects.
-
2-3/8" cutting length provides controlled depth in common wall and cabinet materials, reducing chatter and wandering for plainer edges.
-
3/8" shank fits a wide range of drill chucks and mandrels, ensuring broad compatibility with your existing setup.
-
Quick-Change System compatible with Snap-Lock Plus Mandrels (DHSAR375, DHSAR500, DHSARSDS) for fast, tool-free bit swaps on the fly.
-
Arbor not included—use only with a compatible Snap-Lock Plus Mandrel System for safe, reliable operation.
Ideal use cases
- Routing electrical openings for outlets, junction boxes, and conduit runs in wood, plywood, and composite panels.
- Creating ventilation or plumbing pass-throughs in cabinets, walls, and pre-fabricated enclosures.
- General-purpose hole cutting in soft metals and plastics where a durable, long-lasting hole saw is beneficial.
How to get the best results
- Mount the hole saw to a compatible Snap-Lock Plus mandrel and secure firmly.
- Mark the pilot location and start at a low drill speed to establish the center.
- Apply steady, moderate pressure and let the carbide teeth do the cutting—avoid forcing the tool through material.
- For metal or dense plastics, use light lubrication or cooling to reduce heat buildup and extend tooth life.
- After cutting, remove chips and deburr the edge for a clean finish.
