01R234 - Walter SST+ 17/32" Drill Bit, 3/8" Reduced Shank, 135° Split Point

Precision Drilling for Tough Alloys

The Walter 01R234 SST+ Drill Bit represents the pinnacle of drilling technology for maintenance, repair, and operations (MRO) professionals who demand reliability and precision. Engineered specifically for high-tensile materials, this 17/32-inch bit features Walter’s proprietary SST+ geometry. This design is optimized to cut through stainless steel, mild steel, and non-ferrous metals with exceptional efficiency, reducing the heat generation that typically leads to premature bit failure or material work hardening.

One of the standout technical features of this tool is its 3/8-inch reduced shank. In industrial environments, operators often encounter situations where a hole diameter exceeding 1/2 inch is required, yet the available portable drilling equipment is limited to a standard 3/8-inch chuck capacity. The 01R234 bridges this gap, allowing for the creation of 17/32-inch holes without the need for heavy-duty 1/2-inch drills or stationary machinery. This versatility makes it an essential component of any mobile tool crib or maintenance cart.

Accuracy is paramount in metal fabrication, and the 135° self-centering split point on this bit ensures exactly that. Unlike standard 118° points that tend to "walk" across the workpiece before penetrating, the split point bites into the metal immediately upon contact. This eliminates the need for pre-drilling pilot holes or using a center punch, significantly streamlining the workflow. Furthermore, the aggressive cutting angle requires less feed pressure, reducing operator fatigue during repetitive drilling tasks.

Durability is at the core of the Walter SST+ series. The metallurgy and heat treatment processes used in manufacturing these bits ensure they maintain their cutting edge longer than standard high-speed steel bits, even when subjected to the abrasive nature of stainless steel. Whether used for drilling round surfaces, enlarging existing holes, or fabricating new components, the Walter 01R234 delivers consistent, burr-free performance that meets the rigorous standards of the industrial sector.
