05A500 - Walter Corecut SST 2-Inch Annular Cutter with 3/4-Inch Weldon Shank

Precision Engineering for Industrial Drilling

The Walter Corecut SST 2-inch Annular Cutter (SKU: 05A500) represents the pinnacle of hole-making technology for industrial fabrication. Designed to meet the rigorous demands of structural steelwork and heavy manufacturing, this cutter utilizes Walter's exclusive Super Speed Tip (SST) geometry. Unlike traditional twist drills that must remove all material within the hole's diameter, this annular cutter only removes a narrow periphery, ejecting a solid slug. This mechanical advantage significantly reduces the horsepower required and allows for much faster penetration rates, even in large 2-inch diameter applications.

A defining feature of the 05A500 is its state-of-the-art bronze surface treatment. This specialized coating is not merely aesthetic; it serves a critical tribological function by smoothing the microscopic surface of the tool. By eliminating surface porosity, the treatment drastically reduces the coefficient of friction between the tool and the workpiece. This reduction in friction translates directly to lower operating temperatures, which is the primary factor in preserving the temper and cutting edge of High-Speed Steel (HSS) tools. Consequently, operators experience extended tool life and consistent performance over hundreds of holes.

The cutter is engineered with a 2-inch cutting depth, making it suitable for drilling through thick plates, stacked laminates, and heavy I-beams. The 3/4-inch Weldon shank ensures a secure, slip-free connection with the vast majority of magnetic drilling units available on the market. The flute geometry is optimized to work in concert with the bronze coating, facilitating the rapid evacuation of hot chips away from the cutting zone. This efficient chip management prevents clogging and binding, ensuring that the cutter maintains its speed and precision throughout the drilling cycle. For maintenance and repair operations (MRO) or production environments requiring precise, burr-free holes, the Corecut SST offers a reliable, high-performance solution.
