05D701 - Walter 1-1/16 Inch x 3 Inch Carbide Tipped Annular Cutter

Precision Drilling for Hardened Alloys

The Walter 05D701 1-1/16" x 3" Carbide Core Cut Annular Cutter represents the pinnacle of drilling technology for industrial fabrication. Designed to meet the rigorous demands of modern manufacturing and construction, this cutter is engineered specifically for processing large diameter holes in extremely tough and abrasive materials. Unlike standard High-Speed Steel (HSS) bits that may struggle or dull quickly against hardened substrates, the Carbide Core Cut series utilizes premium tungsten carbide tips. These inserts are brazed onto a specialized alloy body, allowing the tool to maintain its cutting edge even under high thermal stress and mechanical load.

One of the standout features of this tool is its advanced flute and body design. The geometry is optimized to evacuate chips rapidly, preventing clogging and heat accumulation—two primary causes of premature tool failure. This design enables operators to run their magnetic drilling units at higher speeds and feed rates, significantly reducing cycle times on production runs. Whether you are drilling into stainless steel, cast iron, or other high-tensile alloys, the 05D701 delivers clean, burr-free holes with exceptional dimensional accuracy.

For fabricators working on complex projects, versatility is key. This cutter excels not only on flat plates but also on uneven or curved surfaces, where traditional twist drills often wander or bind. The 3-inch cutting depth provides ample capacity for drilling through thick structural beams, pipe walls, and heavy machinery components. By choosing Walter's Carbide Core Cut technology, you are investing in a tool that reduces downtime associated with bit changes and sharpening, ultimately lowering the cost per hole in your operations.

Technical Specifications & Performance

The 05D701 is built to withstand the vibration and torque inherent in heavy-duty magnetic drilling. Its shank is designed for secure retention in standard arbors, ensuring maximum power transfer from the motor to the workpiece. The carbide composition is selected for its balance of hardness and toughness, resisting micro-chipping that can occur when entering or exiting the cut. When paired with appropriate coolant or cutting lubricants, the lifespan of this cutter is extended even further, making it a staple in professional machine shops and field service trucks alike.
