Walter SST Corecut 1-7/16 Inch x 1 Inch Annular Cutter with Universal Shank

Superior Performance in Stainless Steel Drilling

For welders and fabricators, hole preparation is a critical step that can dictate the quality of the final assembly. The Walter 05E107 1-7/16" x 1" SST Corecut Annular Cutter is engineered to solve the common challenges associated with drilling large diameter holes in metal. Traditional drilling methods often result in rough finishes, out-of-round holes, and significant burrs that require time-consuming grinding to remove. The SST Corecut utilizes advanced geometry and precision grinding to deliver a hole that is accurate to size and virtually burr-free, allowing for immediate bolt insertion or welding without extra prep work.

The "SST" designation stands for Walter's proprietary material blend, which is optimized for high-tensile materials. Stainless steel is notorious for work-hardening if the cutting tool dwells or dulls, creating a hard spot that ruins bits. The 05E107 features a sophisticated tooth geometry that promotes aggressive cutting action and efficient chip evacuation. This keeps the cutting zone cooler and prevents the work-hardening effect, ensuring the cutter stays sharp and the material remains workable. The 1-inch depth of cut is perfect for standard plate and structural tubing applications found in heavy fabrication.

Compatibility is key in a busy shop. The 05E107 features a Universal Shank that bridges the gap between different tool holding systems. Whether your rig uses a standard two-screw Weldon chuck or a tool-free quick-change arbor, this cutter locks in securely. This secure connection ensures maximum torque transfer and eliminates slippage, which is vital for maintaining safety and tool integrity during heavy cuts. With the ability to be resharpened, this cutter is not just a consumable; it is a long-term asset for your fabrication toolkit.

Technical Advantages:

• Advanced Geometry: Alternating tooth angles balance cutting forces for smooth penetration.
• Heat Management: Specialized flute design ejects hot chips rapidly to protect the tool and workpiece.
• Universal Fit: Two flat sections for Weldon screws and positioning for quick-connect arbors.
• Material Mastery: specifically hardened to excel in stainless steel, mild steel, and aluminum.
