01K006 - Walter SST+ Double-Ended Stub Drill Bit, 3/32 Inch Cobalt HSS

Maximize Drilling Efficiency with Walter SST+ Double-Ended Stub Bits

The Walter 01K006 3/32" SST+ Double-End Stub Drill Bit is engineered to redefine performance standards in industrial drilling applications. Designed specifically for sheet metal and thin-walled materials, this tool combines the economic advantage of a double-ended design with the superior durability of a premium cobalt High-Speed Steel (HSS) blend. Unlike standard black oxide bits that dull quickly under thermal stress, the SST+ series utilizes a specialized cobalt alloy that maintains hardness at high temperatures, significantly extending the service life of the cutting edges.

Precision is paramount when working with thin gauge metals. This drill bit features a sophisticated self-centering split point geometry that bites into the material immediately upon contact. This eliminates the common issue of "walking" or wandering across the workpiece, ensuring accurate hole placement without the need for a center punch. The short "stub" length adds structural rigidity, reducing the likelihood of breakage under the lateral forces often applied during hand-held drilling operations.

Productivity is further enhanced by Walter's proprietary "High Flow" flute design. This geometry optimizes chip evacuation, preventing clogging and heat buildup that can compromise the temper of the bit. Coupled with the SST surface treatment—which reduces friction and promotes smoother cutting action—this drill bit delivers faster penetration rates and cleaner holes with minimal burr formation. Whether utilized in automotive bodywork, aeronautical fabrication, or general HVAC installation, the Walter SST+ Double-End Stub Drill stands as a pinnacle of drilling technology.
