Silverline DIY & Tools Power Tools Titanium-Coated HSS Step Drill Bit 4–26mm for Precision Metal and Plastic Drilling

The Silverline Titanium-Coated HSS Step Drill 4-26mm is the professional’s choice for precision drilling in sheet metals, alloys, and plastics up to 4mm thick. Engineered with a self-starting tip, this step drill eliminates the need for pilot holes, delivering clean, burr-free holes ideal for automotive, HVAC, and a variety of DIY projects. Its robust HSS core, enhanced by a titanium coating, ensures superior durability, reduced friction, and a significantly extended tool life, even during prolonged use. Featuring clearly marked 2mm graduations, users can achieve accurate depth control and precise hole sizing from 4mm up to 26mm. The 12mm precision-machined shank fits securely in standard drill chucks, allowing quick and stable bit changes for greater efficiency on the job. The titanium coating minimises heat buildup, while laser-etched markings stay visible project after project. For best results, simply secure in your drill chuck, align the self-starting tip at a right angle to your chosen material, and begin drilling at a low speed, increasing as needed. When working with metals, using a cooling lubricant is recommended to further reduce heat and prolong the bit life. Always observe safety precautions by wearing goggles and gloves. Avoid excessive pressure and only use on intended materials — not suitable for masonry, hardwood, or thick metals. Store in a dry, cool place to prevent corrosion and keep out of reach of children. Choose the Silverline Titanium-Coated HSS Step Drill for reliable, professional-grade results every time.
