Foret étagé M35 Cobalt pour acier inoxydable et métal 15 étapes 4 à 32 mm

M35 Cobalt Step Drill Bit: The Versatile Solution for Stainless Steel and Metal. Optimize your workshop with our M35 Cobalt step drill bit, an essential tool designed for professionals and demanding DIYers. This multi-step drill bit, covering a diameter range of 4 to 32 mm across 15 steps, is the ideal investment to simplify your drilling tasks in stainless steel, metal, sheet metal, and other robust materials. No more constantly changing bits: this single drill bit replaces an entire set of traditional drill bits, saving you valuable time and improving your work efficiency. Why choose an M35 steel drill bit with cobalt? The M35 high-speed steel (HSS) composition enriched with cobalt (5%) offers exceptional resistance to heat and wear. Unlike standard drill bits, cobalt increases hardness and edge retention, allowing for higher drilling speeds without the risk of overheating. This results in a longer tool life and clean, precise holes, even in hard materials like stainless steel. The specific tip geometry ensures self-centering, preventing the drill bit from slipping when starting to drill. Versatility and Precision in 15 Steps: This step drill bit is designed to create holes of various diameters without complex adjustments. With its 15 distinct steps, it covers all common needs in plumbing, electrical work, metalwork, and general construction. Whether you need to install cables, fix pipes, or assemble metal structures, this tool adapts perfectly. The markings engraved on each step allow for quick and precise visual identification of the selected diameter, ensuring millimeter accuracy for every project. Robust Design and Easy to Use: The standard cylindrical shank ensures universal compatibility with most electric drills and screwdrivers on the market. The black oxidized finish reduces friction and improves chip evacuation, contributing to smoother and quieter drilling. The optimized tip angle facilitates penetration into the material, reducing the physical effort required and user fatigue. Usage Tips for Optimal Results: Rotation Speed: Match your drill speed to the material. For stainless steel, use a slow to medium speed to prevent overheating. Lubrication: The use of cutting lubricant or drilling oil is highly recommended, especially for stainless steel, to extend drill bit life and achieve a flawless finish. Pressure: Apply constant, moderate pressure. Let the drill bit cutting edge do the work; excessive pressure can damage the steps. Safety: Always wear safety glasses and securely clamp the workpiece. This M35 step drill bit is the essential tool for anyone seeking precision, durability, and efficiency in metalworking. Add it to your toolbox to transform your drilling tasks into a simple and professional experience.
