05A408 - Walter SST Core Cutter 1-1/2" x 2" Annular Bit

High-Performance Drilling with Walter SST Technology

The Walter 05A408 SST Corecut is a premium annular cutter designed to redefine efficiency in heavy-duty industrial drilling applications. Engineered with a diameter of 1-1/2 inches and a cutting depth of 2 inches, this tool is built to handle the most demanding materials found in fabrication shops and construction sites. The defining feature of this series is the exclusive Super Speed Tip (SST) surface treatment. This special bronze coating is not merely a cosmetic finish; it is a functional enhancement that eliminates surface porosity. By creating an impeccably smooth surface, the cutter significantly reduces friction between the tool and the workpiece.

Friction is the enemy of tool life, particularly when drilling through tough alloys like stainless steel or structural steel. The SST coating facilitates superior chip evacuation, allowing metal shavings to slide effortlessly up the fully ground, extra-large flutes. This efficient material removal prevents heat buildup, which is the primary cause of premature tool failure. Consequently, operators can run their magnetic drilling units at higher speeds without compromising the integrity of the cutter or the quality of the hole.

Beyond the surface treatment, the geometry of the Walter SST Corecut is optimized for precision. The modern tooth design bites into the material aggressively yet cleanly, producing burr-free holes that often require no secondary finishing. The universal shank ensures compatibility with a wide range of magnetic drilling machines, making this a versatile addition to any tool crib. Whether you are working with aluminum, mild steel, or hardened structural components, the 05A408 delivers consistent, reliable performance that professionals trust.

Key Technical Benefits
