The Annular Hole Cutter TCT 102 x 30mm Weld Shank 31.75mm is a cutting tool designed for creating precise, large holes in metal materials, typically used with a magnetic drill. Here are the key features: 102mm Outer Diameter: The cutter has an outer diameter of 102mm, ideal for drilling large holes in thick metal plates and structures. 30mm Cutting Depth: With a 30mm cutting depth, it is suitable for creating holes that are deep enough to accommodate larger fasteners or bolts. TCT (Tungsten Carbide Tipped): The TCT cutting edges provide exceptional durability and wear resistance, allowing the tool to cut through tough materials like steel, cast iron, and other hard metals. Weld Shank 31.75mm: The 31.75mm weld shank is designed to fit most magnetic drills and ensures secure attachment to the drill, providing stability and reducing vibration during the cutting process. This Annular Hole Cutter is commonly used in metalworking, construction, and engineering industries for creating precise holes with minimal material wastage, particularly in applications that require large, deep holes for structural or mechanical purposes. The TCT material ensures longevity and sharpness throughout its use.
