OVERVIEW

High-Performance Cobalt Drilling Solution

The Walter 01A529 29/64" SST+ Drill Bit is a premium cutting tool designed for industrial environments where precision, speed, and durability are paramount. Engineered with a specialized cobalt blend, this bit is specifically formulated to withstand the high temperatures generated when drilling through hard materials such as stainless steel and other ferrous alloys. The inclusion of cobalt in the High-Speed Steel (HSS) matrix significantly increases the red hardness of the bit, preventing edge failure under thermal stress.

A key technical feature of the SST+ series is the 135° split point geometry. Unlike standard 118° points, this design allows the bit to self-center immediately upon contact with the workpiece, effectively eliminating "walking" or wandering, even on curved surfaces like pipes and tubing. This precision reduces the need for pre-drilling or center punching, streamlining the fabrication workflow. The bit also features a unique "High Flow" flute design, which is optimized to evacuate chips rapidly. Efficient chip removal is critical in deep hole drilling to prevent heat accumulation and binding.

The body of the drill bit is fully ground and treated with a special bronze SST surface coating. This treatment not only provides corrosion resistance but also reduces the coefficient of friction between the tool and the material, resulting in smoother cuts and less torque requirement from the power source. Whether utilized in a stationary drill press or a portable hand drill, the Walter SST+ delivers consistent, round holes with minimal burr formation.

FAQ

The Walter SST+ is designed to drill through a wide range of materials, including mild steel, stainless steel, and non-ferrous metals like aluminum.

No, the 135° split point geometry allows the bit to self-center, preventing walking and eliminating the need for a center punch in most applications.

The cobalt blend increases the heat resistance and hardness of the bit, allowing it to maintain a sharp cutting edge even when drilling tough materials like stainless steel.

Yes, the Walter SST+ is designed for use in both portable hand drills and stationary drill presses.

The bronze SST surface treatment reduces friction during drilling, which helps lower heat generation and extends the overall life of the tool.

Yes, the self-centering split point makes it ideal for drilling into round surfaces like pipes and tubing without slipping.

It refers to the specific geometry of the flutes that allows for rapid chip evacuation, preventing clogging and heat buildup inside the hole.
