Walter SST+ 3/32 Inch Cobalt Drill Bit for Stainless Steel

The Welder's Choice for Stainless Steel Preparation

Fabricators and welders know that preparing metal is half the battle, and when it comes to drilling pilot holes or clearing out rivets in stainless steel, the Walter 01A506 3/32" SST+ Drill Bit is an indispensable asset. Standard drill bits often burn out or snap when faced with the high tensile strength and work-hardening properties of stainless steel. The SST+ is specifically formulated with a cobalt blend to resist the intense heat generated during these applications, ensuring the cutting edge stays sharp longer.

Precision is key in welding fabrication. The 135-degree split point on the SST+ bit allows for exact placement without the need for a center punch. This is particularly useful when working on vertical surfaces or in tight positions where swinging a hammer for a punch is difficult. The bit starts cutting instantly, providing a clean entry point. This feature, combined with the heavy-duty web construction, provides the rigidity needed to drill straight, accurate holes every time, which is essential for tapping or rivet installation.

Efficiency in the shop leads to profitability. The innovative flute geometry of the SST+ series is designed to eject metal chips rapidly. In deep hole drilling or heavy-duty applications, this prevents clogging and reduces the thermal load on the tool. The bronze surface treatment acts as a lubricant, further smoothing the cutting process. For welders working with mixed materials—from aluminum to structural steel—having a reliable bit that doesn't require constant sharpening or replacement saves valuable time. The Walter 01A506 is built to withstand the abuse of a busy fabrication shop, delivering performance you can trust.

Durability That Lasts

Why settle for disposable bits that fail after a few holes? The Walter SST+ is an investment in productivity. Its solid construction and advanced metallurgy mean it can handle higher feed rates and speeds than conventional bits. Whether you are drilling out spot welds or creating mounting points for fixtures, this 3/32" bit provides the bite and stamina required for professional-grade metalworking.
