Heavy-Duty Annular Cutting System
\nEngineered for magnetic drill presses, delivering clean, burr-free holes in structural steel with unmatched efficiency and tool life.
\nM42 HSS Cobalt Alloy
\nPremium high-speed steel with 8% cobalt content for superior red hardness, allowing continuous cutting at high speeds without tempering loss. Ideal for stainless, alloy steels, and cast iron.
\nPrecision Ground Flutes
\nUltra-smooth chip evacuation design minimizes friction and heat buildup. Each cutter is CNC-ground to achieve concentricity within 0.0005 inches for perfectly round, dimensionally accurate holes.
\nWeld-Free Center Pin
\nIntegrated spring-loaded pilot pin with hardened tip ensures exact starting location, eliminates walking, and automatically ejects slugs after cut. No welded joints means zero fatigue failure risk.
\nEngineered for Depth and Diameter Range
\nUniform 1" cutting depth across all 13 pieces enables consistent plunge cuts through structural beams, heavy plates, and rail tracks without step-drilling.
\nStepped diameter progression: from 7/16" up to 1-1/16" by 1/16" increments. Covers pilot holes, bolt clearance, dowel pins, and conduit openings in one kit.
\nUniversal shank design with three flat drive zones ensures compatibility with all major magnetic drill press brands: Jancy, Slugger, Hougen, DeWalt, Milwaukee, and generic units.
\nMaterial optimized geometry: negative rake angle and reinforced core thickness reduce vibration in structural steel up to 400 Brinell hardness. Excellent for I-beams, channels, and angle iron.
\nSlug-free ejection system: each cutter includes a deep slug slot that prevents jamming and allows continuous operation without stopping to clear chips.
\nField-Proven Reliability
\nStructural fabricators and maintenance crews report 3x longer tool life compared to standard HSS annular cutters. The portable foam-fitted case keeps every size organized and protected on job sites.
