01A506 - Walter SST+ 3/32 Inch Cobalt Drill Bit for Stainless Steel

High-Performance Drilling for Tough Alloys

The Walter 01A506 3/32" SST+ Drill Bit is a top-tier cutting tool engineered to meet the rigorous demands of industrial metalworking. Manufactured by Walter Surface Technologies, the SST+ series is renowned for its ability to tackle hard materials that typically degrade standard high-speed steel bits. At the core of its performance is a specialized cobalt blend matrix. This material composition provides significantly higher heat resistance, allowing the bit to maintain its cutting edge even when drilling through work-hardening materials like stainless steel.

One of the standout features of this drill bit is its geometry. It utilizes a 135-degree split point design, which is self-centering. This means the bit bites into the material immediately upon contact, eliminating the frustrating "walking" or skating effect often seen with standard 118-degree points. This precision makes it an excellent choice for CNC operations, stationary drill presses, and hand-held drilling alike, where accuracy is paramount. The fully ground body ensures that every hole is concentric and true to size, reducing the need for secondary reaming operations.

Chip evacuation is a critical factor in drill bit longevity, and the SST+ excels here with its "high flow" flute design. By efficiently channeling chips away from the cutting zone, the bit prevents heat buildup—the primary enemy of cutting tools. To further enhance performance, the bit features a unique bronze SST surface treatment. This coating reduces friction between the bit and the workpiece, allowing for smoother drilling action and faster penetration rates. Whether you are working with mild steel, aluminum, or challenging stainless steel alloys, the Walter 01A506 delivers consistent, reliable results.

Key Benefits for Industrial MRO

Maintenance and repair operations often require tools that can handle unpredictable materials. The versatility of the SST+ 3/32" bit makes it a staple in any tool crib. Its robust construction resists breakage under torque, while its ability to drill more holes per bit translates to lower cost-per-hole and less downtime spent swapping out dull tools. For professionals seeking efficiency and precision, this Walter drill bit is the definitive choice.
