Annular cutters (broach cutters) remove only the outer ring of material to drill large holes in steel quickly and with less power than twist drills. Use them in magnetic drills for structural steel and fabrications.
What is an annular hole cutter used for?
Annular hole cutters (also known as broach cutters or core drills) are designed for cutting precise, clean holes in metal—especially steel, stainless steel, cast iron, and aluminum. Unlike twist drills, they cut only the outer edge of the hole, creating a solid slug in the center. This reduces cutting force and allows for faster drilling, longer tool life, and smoother finishes, particularly in structural steel, I-beams, and thick metal plates.
What are the advantages of annular cutters over twist drills?
Faster cutting with less effort due to reduced contact area
Cleaner, burr-free holes with minimal deformation
Longer life when used with correct speed and lubrication
Larger diameter holes (typically 12 mm to 100+ mm) with better accuracy
They’re ideal for magnetic drills, drill presses, and milling machines with appropriate arbors.
What should I consider when selecting an annular cutter?
Shank type:
Weldon shank (19 mm or 32 mm) is most common for mag drills
Universal shanks may require an adapter
Material:
HSS (High Speed Steel) for general use
Carbide-tipped for hardened or abrasive materials
Cutting depth: standard lengths are usually 25 mm (1") or 50 mm (2")
Pilot pin compatibility: ensures accurate centering and slug ejection
Using cutting fluid or coolant is essential to prevent overheating and extend cutter life.
