Walter SST+ Heavy Duty Cobalt Drill Bit, Wire Gauge #59

Unmatched Speed and Durability for Metal Fabrication

Upgrade your fabrication toolkit with the Walter SST+ Jobber Drill Bit #59, a tool designed to cut through the frustration of drilling hard metals. For welders and fabricators, time is money, and struggling with dull or broken bits is a costly inefficiency. The Walter SST+ series (SKU: 01-B-559) is crafted with a premium cobalt blend that stands up to the rigors of drilling stainless steel, mild steel, and non-ferrous metals. This robust material composition ensures that the bit stays sharp longer, providing more holes per bit and reducing downtime for tool changes.

One of the standout features of this drill bit is its self-centering capability. The 135° split point geometry allows you to start drilling exactly where you need to, without the bit "walking" across the surface of the workpiece. This is particularly beneficial when working on round surfaces or pipes where stability is often a challenge. The "Speed Tip" design not only improves accuracy but also reduces the amount of feed pressure required, making the drilling process less physically demanding and faster.

The SST+ drill bit also excels in chip management. Its advanced flute design is engineered to pull debris out of the hole quickly and efficiently. This prevents clogging and overheating, two common causes of premature bit failure. The bronze surface treatment further aids in smooth operation by acting as a lubricant barrier against the workpiece. Whether you are drilling pilot holes for tapping or creating clearance holes for fasteners, the Walter SST+ #59 delivers clean, round, and precise holes with minimal burring. It is the ultimate choice for professionals who demand high-performance tooling for their welding and fabrication projects.
