HSB4125 – Malco® 4‑1/8" (102 mm) Bi‑Metal Hole Saw

The Malco® HSB4125 4‑1/8" (102 mm) Bi‑Metal Hole Saw is engineered for clean, controlled cutting in larger‑diameter applications. Designed for HVAC, electrical, plumbing, and general construction professionals, it delivers smooth, accurate holes for duct penetrations, equipment clearances, and heavy‑duty rough‑ins.
A high‑speed steel cutting edge paired with a variable tooth pitch allows the HSB4125 to cut efficiently through wood, drywall, plastic, aluminum, and thin steel while minimizing vibration and chatter. This results in improved control, cleaner edges, and reduced operator fatigue during repetitive drilling.
The flexible alloy body resists cracking and tooth stripping under demanding jobsite conditions, providing long‑term durability and dependable performance. Built for professional setups, this hole saw is compatible with Malco Quick Connect arbors and quick‑change pilot drills using a standard 5/8‑18 thread, allowing for fast changeovers and efficient workflow.
