Featuring a self-starting design, this drill eliminates the need for pilot holes, offering quick and accurate drilling from the very first use. Crafted from high-speed steel with a durable titanium coating, it delivers enhanced longevity, reduced friction, and reliable performance even during prolonged or demanding jobs. The bit includes clearly marked 2mm graduations, enabling precise control over hole size and depth for projects requiring exact results. Its 12mm shank ensures a secure fit with standard drill chucks, maximizing compatibility and stability during use. The Silverline step drill produces clean, burr-free holes, making it ideal for tasks in HVAC, automotive, or general DIY settings. Simply insert the shank, align the tip perpendicular to the work surface, and begin drilling at a low speed—gradually increasing as needed. For metals, cooling lubricants are recommended to help prevent overheating and extend tool life. Always wear appropriate safety gear, avoid applying excessive pressure, and store the drill bit in a cool, dry place. Not recommended for masonry, hardwood, or thick metals.
