01E619 - Walter SST Wire Gauge Drill Bit Set #1-#60 with Metal Index

Precision Drilling with the Walter SST Wire Gauge Set

The Walter 01E619 SST Drill Set is an essential acquisition for any machining or fabrication workshop requiring high-precision hole making. This comprehensive set covers the entire standard wire gauge spectrum from #1 to #60, ensuring you always have the exact diameter required for specific tapping operations, clearance fits, or rivet holes. The bits are manufactured using Walter's proprietary SST (Super Speed Tip) technology, which incorporates a cobalt-blended high-speed steel formulation. This material choice significantly enhances red hardness, allowing the bits to maintain their cutting edge even under the high thermal loads generated when drilling tough alloys like stainless steel.

Organization is critical in a high-throughput environment. This set is supplied in a robust metal index container designed to withstand the rigors of daily industrial use. The internal panels are hinged and fold out neatly, presenting the bits in tiered rows. Each slot is clearly marked with the corresponding wire gauge size, eliminating the time-consuming process of caliper-checking bits or guessing sizes. The metal construction of the case offers superior protection compared to plastic alternatives, shielding the precision-ground flutes and points from damage during storage or transport.

Technically, these bits feature a self-centering split point geometry (typically 135°), which prevents walking on the workpiece surface and reduces the thrust force required to initiate the cut. This is particularly advantageous when working with round stock or curved surfaces where bit wander is a common issue. Whether you are drilling mild steel, aluminum, or work-hardening stainless steel, the Walter SST set delivers consistent, accurate performance hole after hole.
