01D595 - Walter SST+ 9.50mm High-Performance Cobalt Drill Bit

High-Performance Drilling for Industrial Applications

The Walter SST+ 9.50mm Drill Bit (01D595) represents the pinnacle of drilling technology for maintenance, repair, and operations (MRO) professionals. Designed to tackle the toughest materials found in industrial environments, this drill bit is crafted with a specialized cobalt blend. This material composition significantly enhances the bit's heat resistance and hardness, making it the premier choice for drilling through stainless steel, mild steel, and other hard alloys where standard high-speed steel bits often fail.

One of the standout features of the SST+ series is the exclusive Bronze SST surface treatment. This unique coating serves a dual purpose: it drastically reduces friction between the bit and the workpiece, and it facilitates smoother cutting action. The result is a drill bit that not only cuts faster but also maintains its cutting edge for longer periods, reducing the frequency of replacements and downtime in your shop. The 9.50mm size is a versatile metric dimension, bridging the gap for specific engineering requirements that demand precise hole sizing.

Advanced Geometry for Efficiency

Walter has engineered the 01D595 with a "High Flow" flute design. This geometry is critical for deep hole drilling as it maximizes chip evacuation. By efficiently removing debris from the hole, the bit stays cooler, preventing the work-hardening of sensitive materials like stainless steel. Additionally, the bit features a back-tapered body, a subtle design element that prevents the bit from binding or seizing inside the hole, ensuring a smooth retraction and cleaner hole finish.

For operators working with pipes, tubing, or curved surfaces, the 135° split point is a game-changer. It allows the bit to self-center immediately upon contact, eliminating the dangerous and frustrating "walking" effect common with standard bits. Combined with the Quick Shank design, which ensures a positive, non-slip drive in the drill chuck, the Walter SST+ 9.50mm bit delivers safety, precision, and unmatched performance for every drilling task.
