Walter SST+ 5/64-Inch Cobalt Drill Bit for Stainless Steel

Heavy-Duty Drilling Solution for Fabricators

For professional welders and fabricators, a reliable drill bit is as important as a good torch. The Walter 01A505 5/64" SST+ Drill Bit is built to handle the toughest materials found in the welding shop, including mild steel, aluminum, and notoriously difficult stainless steel. We know that time is money, and stopping to replace a dull or snapped bit in the middle of a fabrication job is a waste of both. Walter's SST+ line is designed to eliminate that frustration by providing a bit that bites hard and lasts long, even when drilling through work-hardened surfaces.

One of the standout features for welders is the bit's ability to drill on round surfaces. When fabricating handrails, roll cages, or piping systems, starting a hole on a curved surface can be difficult with standard bits that tend to wander or "walk" across the metal. The Walter SST+ features a geometry that centers itself, allowing you to drill precisely where you marked, without the need for excessive center punching. This precision is matched by the bit's durability; the heavy-duty body construction resists snapping under the side-loads often applied during hand drilling.

The secret to the 01A505's performance lies in its cobalt blend and Bronze SST surface treatment. This combination allows the bit to cut faster and stay cooler. Heat is the enemy of any cutting tool, and by reducing friction and evacuating chips quickly with the High Flow flute design, Walter ensures that this bit maintains its temper and edge retention far longer than generic alternatives. Whether you are drilling pilot holes for fasteners, clearing out rivets, or prepping material for welding, the Walter 5/64" SST+ bit is the professional choice for getting the job done right the first time.

Why Welders Choose SST+:

• Starts on Contact: ideal for pipe and tubing fabrication.
