DAYDOOR 13/16" Annular Cutter 2PC, 1-3/16"Depth, M2 HSS TiAlN Mag Drill Bit

Key features

• Premium M2 HSS Steel Extends Tool Service Life: Made of authentic M2 high speed steel with HRC 63-66 hardness, these annular cutters deliver high wear resistance, excellent red hardness and reliable impact toughness. They deliver stable performance under heavy load and effectively prevent tooth cracking or breakage. Greatly reduce frequent cutter replacement and lower your operational cost, ideal for structural steel, mild steel and thick plate steel industrial fabrication. Not recommended for hardened steel over HBW 300
• Advanced TiAlN Coating Resists High Heat & Prevents Build-Up Edge: Features premium Titanium Aluminum Nitride (TiAlN) coating with 3000 HV high surface hardness and excellent thermal resistance up to 800°C. The upgraded coating reduces friction for smooth chip evacuation, avoids built-up edges, and retains long-lasting sharpness. It performs excellently in stainless steel and heavy-duty metal drilling for pipes, tubes and various steel workpieces
• Precision Structure Delivers Burr-Free, Zero-Rework Cutting: Built with an upgraded precision cutting system for ultra-clean, burr-free holes with minimal rework. Equipped with a pilot pin for accurate center positioning and an optimized spiral flute for smooth coolant flow and efficient chip removal. The three-tier layered tooth structure supports staged low-loss cutting, while precision tooth geometry enables fast cutting advance and stable cutting. Works as a heavy-duty hole saw for I-beam, H-beam drilling, flange prep, base plate mounting and welding table fabrication
• 3/4" Weldon Shank Universal Mag Drill Compatibility: Designed with a standard 3/4" two-flat Weldon shank and 1‑3/16" (30mm) cutting depth. These mag drill bits are compatible with mainstream magnetic drill models including Hougen, Milwaukee, DeWalt, Euroboor, Ruko, BDS and Alfa. NOT compatible with VersaDrive / Versa‑Chuck rapid‑lock adapters. The limited internal depth of Versa‑Chuck causes pilot pin interference, preventing full seating and locking. They also work with milling machines and large drill presses when paired with a matched arbor (not included) for diverse industrial processing needs
• Wide Material Compatibility & Complete Annular Cutter Set: This all-purpose annular cutter set works on steel, stainless steel, copper, aluminum and alloy steel (workpiece hardness below HBW 300). Ideal for metalworking, shipbuilding, bridge construction and heavy equipment maintenance. The full kit contains 2 pieces of 13/16" annular cutters, 2 pilot pins, 1 hex wrench, 2 durable storage tubes, 1 instruction manual and a premium paper box for easy storage and portability
