Walter 15/32" SST+ Cobalt Blend Jobber Drill Bit

Eat Through Stainless with Walter SST+ 15/32" Bits

If you are tired of burning through cheap drill bits every time you touch a piece of stainless steel, it is time to upgrade to the Walter SST+ 15/32" Drill Bit (SKU: 01A530). Designed specifically for the professional welder and fabricator, this bit is built to handle the abuse of daily shop life. It is not just a drill bit; it is a solution for the frustration of dull tools and work-hardened metals. When you have a deadline to meet, you need a tool that cuts fast and stays sharp, and that is exactly what the SST+ delivers.

The secret sauce is the cobalt blend. Unlike standard black oxide bits that soften up when they get hot, this cobalt-infused alloy loves the heat. It is engineered to drill through materials with high tensile strength, like stainless steel and structural steel, without losing its edge. This means you can drill more holes per bit, spending less time at the grinder sharpening tools and more time fabricating. The 15/32" size is a common requirement for bolt holes and clearance fits, making this a staple for your drill index.

One of the biggest annoyances in drilling is the bit wandering all over the metal before it starts cutting. Walter solved this with a 135-degree split point tip. You can put this bit right on your mark, pull the trigger, and it starts cutting instantly—no center punch required. This is a huge advantage when you are working out of position or on rounded surfaces like pipe and tubing. The bit digs in and holds its center, giving you a clean, accurate hole every time.

Walter also applied their special Bronze SST surface treatment to these bits. You will notice the difference immediately; the bit feels slicker and cuts smoother. This coating helps clear chips out of the hole fast, preventing the bit from binding up or snapping off inside your workpiece. The heavy-duty web construction adds extra strength to the core of the bit, so you can apply the feed pressure needed to cut effectively without worrying about breakage. For welders who demand the best, the Walter SST+ is the only choice.
