01B524 - Walter SST+ #24 Cobalt Jobber Drill Bit for Stainless Steel

High-Performance Drilling for Industrial MRO

The Walter 01B524 #24 SST+ Jobber Drill Bit is a premium cutting tool engineered to meet the rigorous demands of industrial maintenance, repair, and operations (MRO). Manufactured by Walter Surface Technologies, the SST+ series is renowned for its ability to tackle the toughest materials found in modern machinery and infrastructure, including heavy-gauge stainless steel and hard alloys. At the core of this drill bit is a sophisticated cobalt blend high-speed steel (HSS) matrix, which provides exceptional hot hardness. This allows the bit to maintain its cutting edge even under the extreme temperatures generated during continuous drilling applications.

One of the standout technical features of the 01B524 is its exclusive Speed Tip geometry. This 135-degree split point design is self-centering, effectively eliminating the "walking" phenomenon common with standard 118-degree bits. For maintenance professionals, this means precise hole placement without the prerequisite of center punching, saving valuable time during complex repairs. Furthermore, the bit utilizes a "High Flow" flute design which significantly improves chip evacuation. By clearing debris rapidly from the hole, the bit reduces friction and heat buildup—the primary causes of premature tool failure.

Durability is further enhanced by Walter's proprietary bronze SST surface treatment and a back-tapered body design. The back taper reduces surface contact between the bit and the sidewalls of the hole, preventing binding and breakage when drilling deep or through multiple layers of material. Whether utilized in a stationary drill press or a portable hand drill, the Walter #24 SST+ bit delivers consistent, round holes with minimal burr formation. It is an essential component for any tool crib dedicated to efficiency and precision in metalworking.
