Crafted from M2 high-speed steel, this step drill bit creates far cleaner holes and cuts far more smoothly than standard step bits. M2 steel contains 50% more tungsten and 150% more molybdenum than standard tool steel, both critical elements for boosting durability, we further enhance performance with vacuum heat treatment and nitride surface hardening. Its polished stepped edges and clearly marked sizing let you quickly confirm your target hole size mid-drill, so you never have to pause work to check measurements, saving you time and frustration. Made with high-precision CNC machining and refined over years of design tweaks, this bit delivers easier, faster, cleaner cuts that outperform average market options. Built for heavy-duty use, it can drill clean holes in stainless steel (with appropriate applied pressure), hardened metal, mild steel, galvanized steel, aluminum, copper, plastic, wood, other materials of similar or lower hardness, handling up to substantial thicknesses for compatible materials. You won’t need to purchase a full bit kit, as this single step bit includes five pre-marked sizes to drill five distinct hole diameters, eliminating the need to swap out multiple bits and saving you time and effort during your projects. Available sizes: 1/4" to 1-1/8" (Straight), 1/4" to 1-3/8" (Straight), 1/4" to 2" (Spiral), 1/4" to 2-3/8" (Spiral), 1/4" to 3/4" (4 Spiral Flutes)
M2 HSS construction with extra tungsten and molybdenum plus vacuum heat and nitride surface hardening boosts durability and clean accurate hole drilling
Polished stepped surfaces with marked size indicators let you see hole sizes mid drill to save time and avoid stopping work
Five preset marked hole sizes in one bit let you drill multiple hole sizes without swapping tools and handle a wide range of materials
