01E621 - Walter SST+ 21-Piece Heavy Duty Drill Bit Set with Metal Box

Premium Industrial Drilling Performance

The Walter 01E621 SST+ Drill Set is a cornerstone tool for maintenance, repair, and operations (MRO) professionals who demand reliability and precision. This 21-piece set includes a comprehensive range of sizes from 1/16-inch to 3/8-inch in 1/64-inch increments, ensuring you have the right bit for almost any standard drilling task. The bits are engineered using Walter's proprietary cobalt-blend High Speed Steel, which provides exceptional heat resistance and longevity even when drilling through tough materials like stainless steel and hard alloys.

One of the standout features of this set is the Quick Shank technology. Each bit (from 3/16" and larger) is designed with three flat surfaces on the shank, which securely lock into the drill chuck. This eliminates the common frustration of bits spinning under high torque, protecting both the bit and your drill chuck from damage. The 135-degree split point geometry allows for immediate self-centering, preventing the bit from "walking" across the workpiece and removing the need for pre-punching.

The set is housed in a robust metal index container that is built to withstand the rigors of an industrial environment. The internal panels are clearly labeled and hinged, allowing for easy identification and selection of the correct size. Whether you are working in a machine shop, on a construction site, or in a facility maintenance role, the Walter SST+ set delivers consistent, high-performance results.
