05H101 - Walter 1-1/16 Inch Carbide Tipped Annular Cutter with Universal Shank

High-Performance Carbide Drilling Solution

The Walter 05H101 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications. Engineered with a diameter of 1-1/16 inches and a cutting depth of 1 inch, this tool is specifically designed to overcome the limitations of traditional High-Speed Steel (HSS) cutters. By utilizing high-grade carbide inserts, Walter has created a cutter that maintains its hardness and cutting edge even under the extreme thermal stress generated when drilling tough materials like stainless steel, cast iron, and abrasive alloys. This results in significantly faster feed rates and a longer service life, reducing downtime associated with tool changes and sharpening.

The geometry of the Carbide Core Cut series is optimized for efficiency. Unlike twist drills that must convert the entire volume of the hole into chips, this annular cutter removes only a narrow ring of material, ejecting the center as a solid slug. This process requires considerably less horsepower and thrust, allowing for large-diameter drilling on site with portable magnetic drilling units. The specialized flute design further enhances performance by rapidly evacuating chips, preventing clogging and heat accumulation that can work-harden the workpiece. This is particularly critical when working with sensitive alloys where maintaining material integrity is paramount.

Versatility is a core feature of the 05H101. It features a Universal Shank design, making it compatible with a wide array of magnetic drill presses available on the market today without the need for complex adapters. Whether you are fabricating structural steel, repairing heavy machinery, or working on curved surfaces, this cutter provides the stability and aggressivity needed to produce precise, burr-free holes. It excels in applications involving uneven surfaces or interrupted cuts, where standard bits often fail or wander. For maintenance, repair, and operations (MRO) professionals demanding reliability and precision, the Walter Carbide Core Cut is the superior choice.
