01E168 - Walter SST+ Quick Shank Drill Bit Set with Coolcut

High-Performance Drilling for Hard Metals

The Walter 01E168 SST Quick Shank Set is a comprehensive drilling solution engineered for industrial maintenance, repair, and fabrication environments. This set features Walter's premium SST+ (Super Speed Tip) drill bits, which are renowned for their ability to penetrate tough materials such as stainless steel, heavy-duty alloys, and aluminum with exceptional speed and precision. The core of these bits is manufactured from a special High-Speed Steel (HSS) formulation containing cobalt, which provides the necessary hardness and heat resistance to maintain a sharp cutting edge even under high-temperature drilling conditions.

A defining feature of this set is the Quick Shank design. Each bit is equipped with a 1/4-inch hex shank, making them universally compatible with cordless impact drivers and quick-change chuck systems. This design eliminates the common issue of round shanks spinning inside the chuck under heavy load and allows for instantaneous bit changes, significantly improving workflow efficiency. The bits also feature a self-centering split point geometry (typically 135 degrees), which prevents "walking" on the workpiece surface, ensuring precise hole placement without the need for pre-punching.

To further enhance performance and longevity, the set comes complete with Walter's Coolcut lubricant. Using this lubricant during operation reduces friction and heat generation, which are the primary causes of premature bit failure. By combining the mechanical advantages of the SST+ design with the chemical protection of Coolcut, this set offers a complete system for efficient, high-quality hole making in the most demanding industrial settings.
