01E118 - Walter SST+ 29-Piece Quick Shank Drill Bit Set

High-Performance Drilling for Industrial Applications

The Walter 01E118 SST+ Quick Shank Drill Set is a premium solution for maintenance, repair, and operations (MRO) professionals who demand precision and durability. This 29-piece set is engineered to tackle the toughest materials found in industrial environments, including stainless steel, heavy-duty alloys, and mild steel. At the core of these bits is Walter's proprietary cobalt-blend High Speed Steel (HSS) formulation, which provides superior heat resistance and edge retention compared to standard black oxide bits. This metallurgy allows the SST+ series to maintain cutting performance even at higher temperatures, significantly extending the lifespan of each bit.

One of the standout technical features of this set is the Quick Shank design. On all bits 3/16" and larger, the shank is machined with three longitudinal flats. This geometric modification ensures a positive lock within the drill chuck, completely eliminating the risk of the bit spinning under high-torque loads. This is particularly critical when drilling hard metals where significant feed pressure is required. Furthermore, the 135° split point geometry ensures the bit is self-centering, preventing "walking" on the workpiece surface and eliminating the need for a center punch in most applications. This results in faster penetration rates and more accurate hole placement.

The set covers a comprehensive range of sizes from 1/16" to 1/2" in 1/64" increments, ensuring you have the right tool for tapping, bolting, or riveting preparations. The bits are housed in a robust, shock-resistant polyethylene case that protects the cutting edges during transport and provides easy indexing for quick selection. Whether you are machining parts in a CNC shop or performing field repairs, the Walter 01E118 set delivers the reliability and performance required for professional-grade metalworking.
