Meet the Malco HSB2750 2 3/4" (70 mm) Bi-Metal Hole Saw — a trusted partner for trades professionals who demand clean, precise penetrations day after day. Built to handle the most common jobsite materials, this hole saw delivers reliable performance whether you’re routing through wood, drywall, plastic, aluminum, or thin steel.
Why this hole saw stands out
- Bi-metal construction with a flexible alloy body: Resists cracking and tooth stripping under repeated use, so you can rely on it for daily installs and rough-ins without worrying about frequent replacements.
- High-speed steel cutting edge: Drives into materials with smooth, efficient cutting power, reducing effort and delivering consistently clean holes.
- Variable tooth pitch: Minimizes vibration and chatter for more controlled cuts and crisper edges, even when penetrating tougher workpiece materials.
- Precise 2 3/4" (70 mm) diameter: A versatile size for common pass-throughs in HVAC, electrical, plumbing, and sheet metal installations.
- Quick-connect compatibility: Designed to pair with Malco Quick Connect arbors and Quick Change pilot drills (HHA4 with a high-speed steel pilot drill bit or HHA5 with a carbide-tipped pilot drill bit) for fast, tool-free changes on the jobsite.
- Cross-material performance: Delivers dependable results across wood, drywall, plastic, aluminum, and thin steel, making it a go-to choice for mixed-material projects.
Ideal use cases
- HVAC penetrations where precise, clean holes save time during ducting and mounting.
- Electrical and plumbing rough-ins that require accurate, square-cut passes through multiple substrates.
- Sheet metal and lightweight metalwork where durability and edge quality matter most.
With the Malco HSB2750, you’re choosing a tool designed for consistent performance, durability, and smooth operation across everyday builds and demanding installations. Its combination of a flexible body, robust cutting edge, and smart compatibility ensures you spend less time fighting the tool and more time completing precise penetrations.
Practical tips for best results
- Pair the HSB2750 with the appropriate Malco arbor and pilot drill (HHA4 or HHA5) to enable quick changes and maintain alignment for accurate cuts.
- Mark your drill guide carefully, apply steady feed pressure, and let the cutting edge do the work to minimize heat buildup and edge distortion.
- Use the hole saw for its intended materials in sequence (wood, then drywall, etc.) when switching substrates to preserve tooth life and edge quality.
Whether you’re a professional installer tackling HVAC penetrations, electricians wiring through framed walls, or a handyman handling sheet metal tasks, the Malco HSB2750 2 3/4" Bi-Metal Hole Saw delivers the control, durability, and clean results you expect—time after time.
