05F218 - Walter 18mm Carbide Tipped Annular Cutter 55mm Depth

Precision Drilling for Tough Industrial Metals

The Walter 05F218 18mm x 55mm Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for heavy-duty industrial applications. Engineered specifically to tackle the most abrasive and hardened materials, this cutter bridges the gap between standard high-speed steel performance and the extreme demands of modern fabrication. When faced with substrates such as stainless steel, cast iron, and high-tensile alloys, traditional tooling often fails due to excessive heat generation and rapid edge degradation. The Carbide Core Cut series addresses these challenges with premium tungsten carbide tips that maintain hardness even at elevated temperatures, ensuring consistent cutting performance throughout the tool's lifespan.

One of the defining characteristics of this 18mm cutter is its specialized flute geometry. Designed to evacuate chips rapidly, the body of the cutter reduces friction and heat buildup, which are the primary enemies of tool longevity. This is particularly critical when drilling deep holes up to 55mm, where chip packing can lead to catastrophic tool failure. The advanced design allows for higher feed rates and rotational speeds compared to HSS equivalents, translating to significant time savings on production floors. Furthermore, the precision-ground carbide inserts produce clean, burr-free holes that often eliminate the need for secondary deburring operations, streamlining the workflow for machinists and fabricators alike.

Durability is central to the Walter Carbide Core Cut's value proposition. The carbide tips are brazed using a high-strength process that prevents detachment under the high torque and shock loads typical of magnetic drilling operations. This robust construction makes the 05F218 ideal for use on uneven surfaces or when drilling through overlapping plates, scenarios that typically cause chatter and breakage in lesser tools. Whether utilized in a controlled workshop environment or on a rugged job site, this annular cutter delivers the reliability required for critical structural connections and precision mechanical assemblies.

In addition to its primary application on ferrous metals, this cutter demonstrates exceptional versatility. It effectively processes non-ferrous materials like aluminum, copper, and brass without the galling often associated with standard tooling. This versatility reduces tooling inventory requirements for diverse shops. By combining aggressive cutting action with a design that prioritizes stability and finish quality, the Walter 18mm x 55mm Carbide Core Cut stands as an essential instrument for professionals demanding accuracy and efficiency in every bore.
