The Walter 01A527 SST+ Drill Bit (27/64") is engineered to meet the rigorous demands of industrial maintenance, repair, and operations (MRO). Designed with a proprietary cobalt blend, this tool addresses the common challenges associated with drilling hard ferrous metals, particularly stainless steel. The metallurgical composition provides superior hot hardness, allowing the bit to maintain its cutting edge even under the high thermal loads generated during continuous drilling operations.
A key technical advantage of the SST+ series is its "high flow" flute geometry. This design optimization ensures rapid and efficient chip evacuation, which is critical for preventing heat buildup and work-hardening of the material. Coupled with a heavy-duty, fully ground body, the bit offers exceptional structural integrity and concentricity, minimizing the risk of breakage and ensuring precise hole sizing. The exclusive Bronze SST surface treatment further enhances performance by reducing the coefficient of friction between the tool and the workpiece, thereby lowering torque requirements and extending tool life.
For professionals requiring precision and efficiency, the SST+ drill bit features a self-centering point that eliminates the need for center punching, even on curved surfaces such as pipes or shafts. This capability significantly streamlines workflow in complex fabrication environments. Whether utilized in stationary drill presses or portable power tools, the 01A527 delivers consistent, reliable results across a spectrum of materials including mild steel, non-ferrous metals, and stainless steel alloys.
