05D011 - Walter 11/16" x 1.5" TCT Annular Cutter for Stainless and Hard Metals

High-Performance Carbide Drilling for Industrial Applications

The Walter 05D011 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for heavy industrial environments. Designed to address the limitations of traditional High-Speed Steel (HSS) cutters, this 11/16-inch diameter tool utilizes premium carbide inserts to deliver exceptional hardness and heat resistance. In industrial fabrication, maintenance, and repair operations (MRO), efficiency is measured by the cost per hole and the downtime required for tool changes. The Carbide Core Cut excels in both metrics by providing a significantly longer service life, even when processing challenging materials such as stainless steel, cast iron, and high-tensile alloys.

Engineered with a 1.5-inch depth of cut, this cutter is perfectly suited for drilling through thick plates, structural beams, and pipe flanges. The body of the cutter features a specialized flute geometry that promotes rapid chip evacuation. This is critical when drilling deep holes in hard metals, as chip congestion can lead to excessive heat buildup and catastrophic tool failure. By efficiently clearing debris, the Walter Carbide Core Cut maintains a cooler cutting temperature, preserving the integrity of both the tool and the workpiece. This thermal management is particularly beneficial when working with work-hardening materials like austenitic stainless steel.

For machine shops and fabrication floors utilizing magnetic drilling units, the 05D011 offers a robust solution that maximizes machine uptime. The carbide tips are precision-ground to bite into uneven surfaces without wandering, ensuring accurate hole placement and size tolerance. Whether used for structural steel erection, heavy equipment repair, or custom fabrication, this tool reduces the axial force required by the operator, leading to less fatigue and more consistent results throughout the workday. It is an essential asset for any operation that demands speed, precision, and durability in their metalworking processes.

Technical Specifications and Compatibility

The 05D011 is compatible with standard magnetic drilling machines equipped with a Weldon shank arbor. Its construction is optimized to withstand the high torque and feed pressures associated with core drilling in hard metals. Unlike twist drills that must remove all material from the hole, this annular cutter only removes a narrow ring of material, requiring less power and time to complete the cut. This efficiency makes it the preferred choice for on-site modifications and heavy-duty drilling tasks.
