05A013 - Walter SST Annular Cutter 13/16" x 1" Universal Shank

Advanced Drilling Technology for Industrial Applications

The Walter 05A013 13/16" x 1" SST Core Cutter represents a significant leap forward in hole-making technology for industrial fabrication and maintenance. Engineered by Walter Surface Technologies, this core cutter utilizes a proprietary Super Speed Tip (SST) formulation that addresses the common failure points of standard high-speed steel annular cutters. The defining feature of this tool is its advanced surface treatment technology, which effectively eliminates microscopic porosity on the cutter's surface. In traditional manufacturing, surface irregularities can lead to increased friction, heat buildup, and premature tool failure. By achieving an impeccably smooth finish, the SST Core Cutter minimizes resistance as it penetrates the workpiece, allowing for higher feed rates and reduced machine strain.

Thermal management is critical in heavy-duty drilling, particularly when working with tough materials like stainless steel and structural alloys. The Walter SST Core Cutter features a specialized bronze surface treatment that acts as a high-performance lubricant barrier. This treatment, combined with the cutter's fully ground extra-large flutes, ensures rapid chip evacuation. Efficient chip removal is essential to prevent re-cutting of chips, which is a primary cause of heat generation and tool breakage. The geometry of the teeth is precision-engineered to balance cutting forces, ensuring that the tool maintains its edge sharpness over a prolonged service life, even under the rigorous conditions of continuous industrial use.

Versatility and compatibility are also key design considerations. The 05A013 model is equipped with a universal shank, making it compatible with a broad spectrum of magnetic drilling units and stationary machines without the need for specialized adapters. This universality simplifies inventory management for tool cribs and ensures that operators have the right tool for the job, regardless of the drilling equipment available. Whether applied in structural steel erection, heavy equipment repair, or precision metal fabrication, the Walter SST Core Cutter delivers consistent, burr-free holes with exceptional dimensional accuracy.

Key Technical Benefits:

• Porosity Elimination: Advanced treatment creates a denser, smoother tool surface.
• Thermal Efficiency: Bronze coating reduces friction coefficients significantly.
• Chip Management: Large flute geometry prevents clogging and heat accumulation.
• Material Versatility: High-performance results on aluminum, mild steel, and stainless steel.
