description About this item M35 Cobalt HSS Step Drill: The M35 cobalt HSS step drill is an ideal choice for drilling through a variety of materials such as stainless steel, metal sheet, wood, plastic, aluminum sheet, copper, and other metal sheets. Spiral Flute Design: The spiral-flute design prevents metal filings from flying around and clears chips faster, allowing for smoother drilling without overheating. The split point tip is at 118 degrees to increase wear resistance. Widely Applicable: Our step drill bit can process different diameter holes, making it easy to drill through plastic, wood, plank, and soft rubber with low hardness countersunk. Suitable for home DIY and general building/engineering use. Hex Shank for Quick Change: Our drill bits feature a hex shank that fits easily and securely into all power tools, especially for locking into quick-change chucks. The hex shank also clamps more securely onto pistol drills to prevent slippage and shedding during rotation.
