01C509 - Walter Letter I Sst Drill Bit

Precision and Power: Walter SST+ Letter I Cobalt Drill Bit

For welders and metal fabricators, the quality of hole preparation can make or break a project. The Walter 01C509 Letter I SST+ Drill Bit is engineered to meet the rigorous demands of the welding industry, providing a robust solution for drilling through heavy-gauge metals. With a specific diameter of 0.2720 inches (Letter I), this bit is essential for creating precise pilot holes, clearance holes for fasteners, or preparatory holes for tapping. The core of its performance lies in its advanced cobalt blend construction. This material composition allows the bit to withstand the extreme heat generated when drilling through tough substrates like stainless steel, which is a staple in modern welding shops.

Efficiency on the job site is paramount, and the Walter SST+ delivers with its innovative geometry. The self-centering Speed Tip is a game-changer for welders working in awkward positions or on irregular surfaces. It bites into the metal instantly, preventing the bit from wandering and damaging the surrounding finish. This precision reduces the need for rework and ensures that every hole is perfectly positioned. Additionally, the bit features a unique bronze SST surface treatment. This specialized coating minimizes friction, allowing the bit to cut freely and smoothly while extending the tool's overall life. You spend less time changing dull bits and more time fabricating.

The structural design of the 01C509 is built for heavy-duty use. Its fully ground body and high-flow flutes are optimized to eject chips rapidly. Efficient chip removal is critical when drilling deep holes or thick plates, as it prevents the bit from jamming or snapping under torque. The back-tapered design further reduces drag, enabling the operator to drill more holes per charge on cordless tools or with less fatigue on manual presses. When your work involves structural steel, aluminum alloys, or stainless assemblies, the Walter SST+ Letter I drill bit provides the reliability and cutting aggression needed to get the job done right the first time.

Features for the Professional Fabricator

• Cobalt-Enriched Alloy: Resists high temperatures to maintain hardness in tough drilling applications.
• No-Walk Speed Tip: Ensures accuracy on pipes, tubes, and sheet metal without center punching.
• Bronze Surface Treatment: Promotes smoother cutting action and extends the service life of the bit.
• Versatile Compatibility: Performs exceptionally well in both stationary drill presses and handheld drills.
