HSS Annular Cutters — Industrial Grade Hole Cutters for Steel & Metal
Holesaws.ca supplies the complete range of industrial-grade HSS annular cutters designed for mag drills, drill presses, and metal fabrication. Manufactured from premium high-speed steel (HSS), these cutters deliver precise, burr-free holes in mild steel, stainless, and structural materials — with faster feed rates and extended tool life.
- High-speed steel (HSS) construction for durability, strength, and wear resistance.
- Multiple cutting edges for faster penetration and smooth hole walls.
- Reduced torque design compared to twist drills — less power, more precision.
- 1” & 2” cutting depths available, covering standard industrial drilling needs.
- Universal shank fits all major magnetic drills and arbors.
Professional Cutting Performance
Each HSS annular cutter removes only the material at the periphery of the hole, unlike traditional twist drills that bore the full diameter. This results in faster drilling, cleaner holes, less heat buildup, and dramatically longer tool life. Ideal for fabricators, welders, electricians, maintenance techs, and industrial contractors.
Applications
- Structural steel fabrication
- Metal construction and plant maintenance
- Machinery assembly and repair
- Electrical and HVAC installations
- Automotive and industrial production lines
Material Recommendations
HSS annular cutters excel in mild steel, cast iron, and aluminum. For hardened steels or stainless, use cobalt or carbide-tipped annular cutters for longer life. Apply cutting oil or coolant to enhance performance and prevent overheating.

FAQ — HSS Annular Cutters
What are HSS annular cutters used for?
They’re designed for precise hole cutting in steel, stainless, and aluminum using magnetic or stationary drills.
What’s the difference between annular cutters and hole saws?
Annular cutters remove only the perimeter of the hole for faster, smoother drilling and reduced torque.
Do I need cutting oil with HSS annular cutters?
Yes. Use cutting oil or coolant to reduce heat and extend the tool’s lifespan.
Are they compatible with all mag drills?
Yes, most HSS annular cutters have a 3/4″ or 1-1/4″ Weldon shank compatible with standard mag drill arbors.
