05D920 - Walter 2-1/4 Inch TCT Annular Cutter 4 Inch Depth

High-Performance Drilling for Tough Alloys

The Walter 05D920 Carbide Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial applications involving hard and abrasive materials. Sized at a substantial 2-1/4 inches in diameter with an extended 4-inch depth of cut, this tool is engineered to tackle the most demanding drilling tasks that standard High-Speed Steel (HSS) cutters simply cannot handle. The cutter features premium-grade carbide tips that maintain their hardness and cutting edge even under the extreme heat generated when drilling through stainless steel, cast iron, and other tough alloys.

One of the standout features of the Walter Carbide Core Cut series is its sophisticated body and flute design. The specialized geometry is optimized to clear chips rapidly from the deep 4-inch bore, preventing clogging and reducing the thermal load on both the tool and the workpiece. This results in a cleaner, burr-free hole that often requires no secondary finishing operations. For fabrication shops and manufacturing facilities, this efficiency translates directly to reduced cycle times and increased throughput.

Beyond simple hole creation, this cutter excels in challenging setups. Its robust construction allows it to engage with uneven, curved, or angled surfaces without the "walking" often associated with twist drills. Whether you are drilling into large diameter pipe, structural beams, or heavy castings, the 05D920 provides the stability and aggression needed to penetrate quickly. It is designed for use with magnetic drilling units, making it a versatile solution for both shop floor production and on-site field repairs where precision and speed are paramount.

Durability is central to the Walter brand, and this annular cutter is no exception. The carbide inserts are brazed using advanced techniques to prevent failure under shock loads, ensuring a long service life even in high-vibration environments. By allowing for higher speed and feed rates, the 05D920 not only lasts longer but also gets the job done faster, maximizing the productivity of your magnetic drilling equipment.
