Strovolt TCT Annular Core Cutter 12mm x 50mm Tungsten Carbide Tipped Mag Drill Bit Heavy Duty Rail & Stainless Steel Hole Saw
Product Overview
The Strovolt STRO781250 is a premium 12mm x 50mm Tungsten Carbide Tipped (TCT) Annular Core Cutter engineered for high-speed precision drilling through the toughest materials. Unlike standard HSS bits, this professional-grade cutter features ultra-fine grain carbide inserts that slice through hardened metals like stainless steel, cast iron, and high-tensile structural steel with minimal friction and superior heat resistance.
Constructed with a high-carbon alloy steel body for superior structural integrity and shank strength, the STRO781250 boasts a specialized heat-resistant coating that extends tool life during dry or high-heat drilling applications. Its optimized flute geometry ensures rapid chip evacuation, preventing clogging during deep-hole operations.
With a depth of cut of 50mm (2"), this heavy-duty annular cutter delivers burring-free holes with a mirror-like finish, eliminating the need for pre-drilling or step-drilling. Designed for universal compatibility, it features a standard 19.05mm (3/4") Weldon Shank, making it suitable for most major magnetic drill presses from brands like Hougen, Evolution, Milwaukee, and Euroboor.
Ideal for heavy industry applications such as railway track drilling, bridge construction, and shipbuilding, the Strovolt STRO781250 TCT Annular Core Cutter offers superior performance, efficiency, and durability. With a cutting speed up to 3 times faster than twist drills, it ejects the center core effortlessly via the spring-loaded pilot pin (sold separately), ensuring clean slugs and hassle-free operation.
