01A025 - Walter SST Jobber Drill Bit 25/64 Inch with Quick Shank

High-Performance Walter SST Drill Bit 25/64"

The Walter 25/64" SST Jobber Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered by Walter Surface Technologies, this bit is designed to solve the common frustrations associated with standard high-speed steel bits. At its core, the SST bit utilizes a premium cobalt blend material. This specific metallurgy provides exceptional heat resistance, allowing the bit to maintain its cutting edge even under high-temperature conditions often generated when drilling through tough alloys and mild steel. This durability translates directly to a longer service life, reducing the frequency of bit replacements and lowering overall consumable costs for workshops and industrial facilities.

One of the standout features of this model is the exclusive Quick Shank technology. Traditional round shanks often suffer from slippage inside the drill chuck, especially when high torque is applied or when the bit bites into the material. The Quick Shank design incorporates engineered flats that allow the chuck jaws to grip the bit securely, effectively eliminating slippage. This feature is particularly beneficial for users of keyless chucks and cordless power tools, ensuring that every rotation of the motor is transferred directly to the cutting edge. Furthermore, the efficiency of the cut helps to maximize the battery life of cordless tools, allowing operators to drill more holes per charge compared to standard bits.

Precision is paramount in professional environments, and the Walter SST delivers with its self-centering Speed Tip. This advanced tip geometry prevents the bit from "walking" or wandering across the workpiece surface upon startup, eliminating the need for pre-punching center holes. This saves valuable time during layout and fabrication. The body of the bit is fully ground and features a back-tapered design, which reduces friction along the sidewalls of the hole. Combined with the special bronze SST surface treatment, this design facilitates smooth chip evacuation and prevents binding, even when drilling through multiple layers of thin gauge metal. Whether you are working with aluminum, mild steel, or non-ferrous metals, the Walter 01A025 provides the reliability and performance demanded by professional technicians.
