Malco HSB3625 3-5/8" (92 mm) Bi-Metal Hole Saw for Wood, Drywall, Plastic, Aluminum & Thin Steel – Variable Tooth Pitch, High-Speed Steel Cutting Edge
MPN: HSB3625
Minimum order quantity is .
The Malco HSB3625 3-5/8" (92 mm) Bi-Metal Hole Saw is engineered for professionals who demand clean, accurate holes across the most common jobsite materials. With a high-speed steel cutting edge and a variable tooth pitch, it slices through wood, drywall, plastic, aluminum, and thin steel while minimizing vibration and chatter for consistent, plug-free results.
Smart design for durable performance
Bi-metal construction blends a flexible alloy body with a tough high-speed steel edge, resisting cracking and tooth stripping even under repeated use. This reliability translates to dependable performance on everyday installs and rough-ins—whether you’re punching through walls, partitions, or metal siding.
Key features that set the HSB3625 apart
- Variable tooth pitch provides smoother cuts and efficient chip clearance across materials of different densities.
- High-speed steel cutting edge for fast material removal and extended edge life on common jobsite substrates.
- Flexible alloy body reduces cracking and tooth stripping during repeated use, boosting longevity.
- Bi-metal durability supports reliable performance through HVAC penetrations, electrical and plumbing work, and sheet metal tasks.
- Compatibility works with Malco Quick Connect arbors and Quick Change pilot drills (HHA4 Arbor with High Speed Steel Pilot Drill Bit or HHA5 Arbor with Carbide Tipped Pilot Drill Bit).
What you can accomplish with this hole saw
Designed for versatility, the HSB3625 handles a wide range of materials with precision. It delivers clean edges that reduce the need for touch-up work, speeding up installs and rough-ins alike. This makes it ideal for contractors and technicians tackling multiple trades in a single project.
- HVAC installations: clean, accurate penetrations through studs and sheathing.
- Electrical and plumbing penetrations: precise openings for conduits, boxes, and fittings with minimal rework.
- Sheet metal and light metal tasks: true holes in aluminum and thin steel without feathering or burrs.
Specifications
- Diameter: 3-5/8" (92 mm)
- Material: Bi-Metal with a High-Speed Steel cutting edge
- Tooth pitch: Variable
- Body: Flexible alloy designed to resist cracking and tooth stripping
- Arbor compatibility: Malco Quick Connect arbors; HHA4 (HS) or HHA5 (Carbide Tipped Pilot)
- Compatible materials: Wood, Drywall, Plastic, Aluminum, Thin Steel
Practical tips for best results
- Center your pilot bit to begin with a precise starter point to prevent wandering.
- Choose the appropriate arbor and pilot drill: HHA4 with a High Speed Steel Pilot Drill Bit or HHA5 with a Carbide Tipped Pilot Drill Bit for optimal performance.
- Apply steady, moderate feed pressure and avoid forcing the tool to minimize chatter.
- Use a backer board under soft materials like drywall to reduce breakout and achieve a clean edge.
- Secure the workpiece firmly to ensure accurate alignment and hole quality.
