Quick-Change Hex Shank: Compatible with power screwdrivers, impact drivers, and other tools that accept 1/4″ hex shanks, allowing for quick changing between multiple drill bits and screwdriver bits with just one power tool, High-Torque Ready, Built to handle heavy-duty drilling without bending or snapping Tapered Web Reinforcement – Prevents breakage. Widely Use: Work on steel, copper, aluminum, cast iron, zinc alloy, wood & plastic Perfect for DIY & Pros – Ideal for home repairs, workshop projects, and industrial work Impact-Rated – Handles high-torque drilling in tough materials. Please note that they are not suitable for glass concrete or ceramic materials. Pay attention to speed, pressure, and heat control when drilling. Longer Lifespan: M35 Cobalt than standard HSS bits Stays Sharper, Maintains cutting edge even after repeated use Heat & Corrosion Resistant – Performs reliably under heavy-duty conditions. Really Solid Hex Shank: Eliminates Wobbling & Chatter at the source, maintains overall consistency of the bit, and stays vertical during the work process. Twist Design and Performance: Precise 135° Split Point, Prevent walking, clear chips and particles faster.Produced by precision fully ground which ensures chips move smoothly.
