01E678 - Walter SST 29-Piece Drill Bit Set with Quick Shank and Plastic Case

Premium Drilling Performance with Walter SST Technology

The Walter 01E678 SST Drill Bit Set is a comprehensive 29-piece collection designed for professional metalworkers and maintenance personnel who demand reliability and precision. This set includes a full range of jobber-length drill bits from 1/16-inch to 1/2-inch in 1/64-inch increments, ensuring you have the exact size needed for tapping, fastening, or general fabrication tasks. The bits are manufactured from premium High Speed Steel (HSS), engineered to withstand the thermal stresses of drilling through tough materials like mild steel, aluminum, and various non-ferrous alloys.

The Quick Shank Advantage

One of the standout features of this set is the proprietary Quick Shank design found on the larger bits. The shank is engineered with three precision-ground flats that lock securely into the jaws of a standard drill chuck. This design effectively eliminates the common frustration of the bit spinning inside the chuck under high-torque loads, which can damage both the bit shank and the drill's jaws. This positive drive system ensures maximum power transmission from the tool to the workpiece, resulting in faster, more efficient drilling operations.

Precision and Durability

Each bit in the Walter SST set features a 135-degree split point geometry. Unlike standard 118-degree points, this aggressive angle allows the bit to self-center immediately upon contact with the material. This eliminates the tendency for the bit to "walk" or wander across the surface, removing the need for pre-punching a center hole in most applications. The set is housed in a highly durable, shock-resistant polyethylene case. This extra-thick plastic box is designed to survive drops and rough handling on the job site. The internal panels are hinged for easy access and clearly labeled with sizes, making tool selection and organization effortless for the user.
