01D590 - Walter SST+ 9.00mm High-Performance Cobalt Drill Bit

High-Performance Drilling for Industrial Applications

The Walter SST+ 9.00mm Drill Bit (SKU: 01D590) 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 with a proprietary cobalt blend. This material composition provides exceptional hardness and heat resistance, allowing the bit to maintain its cutting edge even when subjected to the high thermal loads generated during heavy-duty drilling. Unlike standard high-speed steel (HSS) bits that may soften and dull rapidly, the SST+ series is built to withstand the rigors of continuous use on work-hardening alloys.

One of the standout features of the Walter 01D590 is its "high flow" flute design. In deep-hole drilling or when working with gummy materials like aluminum or certain stainless grades, chip evacuation is critical. The specialized flute geometry of the SST+ ensures that swarf is ejected efficiently, preventing the packing that often leads to bit breakage or poor hole quality. Furthermore, the bit features a back tapered body. This subtle geometric adjustment reduces the surface area in contact with the hole walls, significantly minimizing friction and drag. The result is a cooler drilling process that requires less torque from the machine and less physical force from the operator.

To further enhance performance, Walter applies a unique bronze SST surface treatment to these bits. This treatment not only identifies the premium line but also adds a layer of lubricity and corrosion resistance. Whether utilized in a stationary drill press for precision fabrication or a portable hand drill for on-site repairs, the Walter SST+ 9.00mm bit delivers consistent, round holes with superior surface finish. It is the ideal choice for facilities processing mild steel, stainless steel, and non-ferrous metals, offering a tangible reduction in cycle times and tool replacement costs.
