Every welder knows the frustration of trying to drill a clean hole in stainless steel with a cheap bit—it smokes, it wanders, and it dulls before you break through. The Walter 01D515 SST+ 1.50mm Drill Bit is the solution to that headache. Built specifically for the tradesman who needs reliability, this bit uses a heavy-duty cobalt blend that eats through hard metals without losing its temper. When you are prepping a piece for fabrication or drilling out a rivet, you need a tool that bites instantly. The SST+ features a self-centering split point that prevents "walking" on the surface, allowing you to start your hole exactly where you marked it, often without needing to reach for a center punch and hammer first.
Heat is the enemy of any cutting tool, especially when working with work-hardening materials like 304 or 316 stainless. Walter has tackled this problem with a unique high-flow flute design that pulls chips out of the hole faster than standard bits. This keeps the cutting edge cooler and prevents the bit from seizing up halfway through the job. The bronze SST coating isn't just for looks; it helps the bit slide through the metal with less resistance, meaning you don't have to lean as hard on your drill to get results. This reduces fatigue on your arm and strain on your power tool's motor.
Versatility is key in any welding shop. While this 1.50mm bit is a beast on stainless, it works just as well on mild steel, aluminum, and other non-ferrous metals. Whether you are drilling pilot holes for larger fasteners or doing precision work on a custom bracket, the Walter SST+ gives you the control and durability you expect from a top-tier brand. Stop wasting money on bits that burn out after three holes. Upgrade to the Walter SST+ and experience the difference that professional-grade geometry and materials make in your daily fabrication work.
