For professional welders and fabricators, time is money, and a broken or dull drill bit can bring a project to a grinding halt. The Walter 01D585 8.5mm SST+ Drill Bit is built to handle the rigors of the welding shop, specifically designed to conquer the materials that defeat lesser tools. If you frequently work with stainless steel, you know the frustration of work hardening—where the metal becomes harder as it heats up, destroying standard bits. The SST+ solves this with a heavy-duty cobalt blend construction that resists high heat and cuts aggressively, allowing you to penetrate stainless steel and other hard alloys quickly and cleanly before work hardening can occur.
Versatility is key in fabrication environments. This 8.5mm bit is not just for stainless; it excels in mild steel, aluminum, and non-ferrous metals, making it a go-to solution for a wide range of tasks. From drilling out rivets and broken bolts to preparing frames for mounting hardware, the SST+ delivers. The 135-degree split point tip is a massive advantage when working out of position or on rounded surfaces like pipe and tubing. It bites instantly without "walking" across the metal, ensuring your holes are exactly where you need them without the extra step of using a center punch.
Walter has also addressed the physical demands of drilling. The unique flute geometry clears swarf and chips efficiently, which means you don't have to push as hard to get the job done. This reduces operator fatigue during long shifts and puts less strain on your power tools. The bronze surface treatment and back-tapered design ensure the bit runs cool and doesn't bind up, even in thick plate. When your reputation depends on quality fabrication and efficient repairs, equip your shop with the drill bit that works as hard as you do—the Walter SST+.
