05F212 - Walter 12mm Carbide Tipped Annular Cutter - 55mm Depth

Precision Drilling for Hardened Industrial Metals

The Walter 05F212 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for heavy industrial applications. Engineered by Walter Surface Technologies, this 12mm diameter cutter is specifically designed to overcome the challenges associated with drilling hard, abrasive, and tough-to-machine materials. Unlike standard High-Speed Steel (HSS) cutters which may struggle or dull quickly when facing work-hardened stainless steel or cast iron, the Carbide Core Cut utilizes premium tungsten carbide inserts. These inserts maintain their hardness at high temperatures, allowing for significantly higher speed and feed rates without compromising the integrity of the tool or the workpiece.

With a cutting depth of 55mm, this tool is versatile enough for thick plate fabrication and structural steel work. The geometry of the cutter features a specialized flute and body design that optimizes chip flow. Efficient chip evacuation is critical in deep hole drilling to prevent binding and heat buildup; Walter’s design ensures that swarf is ejected smoothly, keeping the cutting zone cool and clean. This makes the 05F212 an essential asset for fabrication shops dealing with exotic alloys, rail steel, or maintenance operations requiring on-site drilling of large, immovable workpieces.

Furthermore, the robust construction of the Carbide Core Cut series allows it to perform exceptionally well on uneven or curved surfaces, a scenario where traditional twist drills often wander or break. Whether used in a workshop setting or out in the field with a magnetic drilling unit, this cutter delivers consistent, burr-free holes with tight tolerances. It is the preferred choice for professionals demanding efficiency, longevity, and precision in their metalworking operations.
