01B548 - Walter SST+ #48 Cobalt Jobber Drill Bit for Stainless Steel

High-Performance Drilling for Industrial Applications

The Walter 01B548 #48 SST+ Jobber Drill represents the pinnacle of drilling technology for maintenance, repair, and operations (MRO) professionals. Designed to tackle the toughest materials found in industrial environments, this drill bit is engineered from a proprietary cobalt blend that provides exceptional hardness and heat resistance. Unlike standard high-speed steel bits that dull quickly when facing work-hardening alloys, the SST+ series maintains its cutting edge longer, ensuring consistent performance and reducing the frequency of tool changes. This translates to lower operational costs and increased productivity on the shop floor.

One of the standout features of the SST+ line is the exclusive Speed Tip design. This self-centering point geometry eliminates the need for center punching or pilot holes, even on curved surfaces like pipes and tubing. For fabricators working with complex assemblies, this feature significantly streamlines the drilling process. The bit bites into the material instantly, preventing the "walking" effect that often leads to marred workpieces and inaccurate hole placement. Combined with a robust web construction, the Speed Tip ensures that every hole is precise, round, and true to size.

Thermal management is critical in heavy-duty drilling, and Walter has addressed this with a unique High Flow flute design and a back-tapered body. The specialized flutes are optimized to evacuate chips rapidly, preventing heat buildup that can work-harden the material or damage the bit. The back-tapered body reduces surface contact friction along the sides of the hole, further minimizing heat generation. Finished with a special bronze SST surface treatment, this #48 wire gauge drill bit offers superior lubricity and wear resistance, making it the ideal choice for drilling stainless steel, mild steel, and non-ferrous metals in stationary or portable applications.
