01B535 - Walter SST+ Cobalt Jobber Drill Bit #35

High-Performance Drilling for Industrial Maintenance

The Walter #35 SST+ Jobber Drill Bit (SKU: 01B535) represents the pinnacle of drilling technology for industrial maintenance, repair, and operations (MRO). Engineered by Walter Surface Technologies, the SST+ series is specifically formulated to tackle the toughest materials found in modern workshops, including heavy-gauge mild steel, stainless steel, and other non-ferrous metals. At the core of this tool is a proprietary cobalt blend that provides significantly higher heat resistance than standard High-Speed Steel (HSS) bits, allowing the cutting edge to maintain its hardness even under extreme drilling temperatures.

Efficiency is critical in professional environments, and the SST+ design delivers. It features a unique "High Flow" flute geometry that rapidly evacuates chips from the hole, preventing clogging and heat buildup that often leads to premature tool failure. The body of the bit is back-tapered, a subtle engineering choice that reduces surface contact between the bit and the sidewalls of the hole. This reduction in friction not only extends the life of the tool but also minimizes the torque required by your power tool, preserving battery life on cordless drills and reducing strain on stationary drill presses.

For precision tasks, the Walter #35 bit utilizes an exclusive self-centering "Speed Tip." This 135-degree split point bites into the material immediately upon contact, eliminating the common issue of the bit "walking" or skating across the workpiece. This feature removes the need for pre-punching center holes, streamlining your workflow. Whether you are drilling out broken fasteners, fabricating custom brackets, or performing general assembly, the Walter SST+ #35 provides the reliability and speed demanded by professional tradespeople.
