01J026 - Walter SST+ #26 Cobalt Stub Drill Bit for Sheet Metal

High-Performance Drilling for Industrial Fabrication

The Walter #26 SST Stub Drill Bit (01J026) represents the pinnacle of drilling technology for sheet metal and thin-walled fabrication. Designed specifically to address the common challenges of industrial drilling—such as bit walking, breakage, and rapid dulling—this tool is engineered with a premium cobalt blend that withstands high temperatures and abrasive materials. The "SST" designation signifies Walter's commitment to Super Speed and Toughness, ensuring that this bit maintains its cutting edge far longer than standard high-speed steel alternatives.

One of the standout features of this drill bit is its stub length geometry. By shortening the flutes and overall length, Walter has significantly increased the torsional rigidity of the bit. This is critical in industrial environments where feed pressure can vary or where the workpiece cannot be perfectly clamped. The increased stiffness prevents the flexing that typically leads to snapped bits, making it an economical choice for high-volume shops. Furthermore, the specialized bronze SST surface treatment acts as a lubricant and heat deflector, allowing for smoother chip evacuation and cooler operation even during continuous use.

Precision is paramount in manufacturing, and the 01J026 delivers with its advanced split-point design. This feature allows the bit to self-center immediately upon contact with the material, eliminating the need for center punching and preventing the bit from wandering across the surface. Whether you are drilling into mild steel, non-ferrous alloys, or tough stainless steel, this drill bit provides the consistency and speed required to keep production lines moving efficiently.
