Take on large, demanding holes with confidence using the Blu-Mol Xtreme QuickCore 4 in. Bi-Metal Hole Saw. Built to last, this bi-metal design blends a tough cutting edge with a durable backing, delivering cleaner, more accurate holes through metal while still performing smoothly in wood and plastics.
-
Bi-Metal Durability: A robust combination of high-speed steel teeth and a sturdy body resists dulling and wear, so you can cut through tougher materials without frequent replacement.
-
4-inch Cutting Diameter: Perfect for large pass-throughs, conduit openings, or mounting holes where smaller bits fall short.
-
Quick-Change System: Designed for fast, tool-free changes on compatible arbors, minimizing downtime during multi-size projects.
-
Arbor Not Included: Pair with your preferred Blu-Mol QuickCore arbor (sold separately) to fit your drill setup and workload.
How to use — For best results, pair this hole saw with a compatible Blu-Mol QuickCore arbor and secure your workpiece. Cut at steady speeds with controlled feed pressure, and apply a light lubricant when cutting metal to manage heat and extend the life of the teeth. Maintain alignment and avoid side pressure to ensure perfectly round holes every time.
Who this is for
Electricians, plumbers, and general contractors who need large-diameter holes in metal enclosures, studs, or panels will appreciate the 4-inch bore and resilient bi-metal construction. It’s equally useful for DIY enthusiasts tackling cabinet openings, large hardware installations, or PVC/wood work where a single‑purpose bit won’t cut it.
Why it stands out
Unlike single-material saws, the Blu-Mol Xtreme QuickCore hole saw is built for versatility and longevity. The bi-metal tooth design stands up to metal cutting tasks without sacrificing performance in wood or plastics, while the Quick-Change system reduces downtime, helping you move from one task to the next with minimal interruptions.
