01A029A - Walter SST+ 29/64" Cobalt Drill Bit with Quick Shank

High-Performance Drilling with Walter SST+ Technology

The Walter 01A029A 29/64" SST+ Jobber Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered with a proprietary cobalt blend, this drill bit is designed to withstand high temperatures and extreme stress, making it significantly more durable than standard high-speed steel bits. The core material is formulated to maintain hardness even when drilling through tough alloys like stainless steel, ensuring a longer service life and consistent cutting performance over time. This specific blister-packaged unit ensures the tool arrives in pristine condition, ready for immediate deployment in demanding environments.

One of the standout features of the SST+ line is the exclusive Quick Shank design. Traditional round shanks often suffer from slippage inside the chuck, especially under high torque loads. The Quick Shank features longitudinal ridges that lock into both keyed and keyless chucks, ensuring a secure hold that translates 100% of the drill's power into the cut. This design is particularly beneficial for users of cordless power tools, as the efficient power transfer and aggressive cutting geometry allow for more holes per battery charge, reducing downtime associated with battery swaps.

Precision is paramount in metalworking, and the Walter SST+ delivers with its self-centering "Speed Tip." This 135-degree split point geometry bites into the material immediately upon contact, eliminating the "walking" effect common with standard bits. This means users can forego the time-consuming step of center punching, even when working on curved surfaces like pipes or tubing. Combined with a back-tapered body that reduces side friction and binding, this drill bit offers a smooth, clean operation that minimizes heat buildup and maximizes hole quality.

The bit is finished with a special bronze SST surface treatment, which acts as a lubricant to further reduce friction and facilitate chip evacuation. Whether you are drilling through thin gauge sheet metal, multi-layered stacks, or solid plate, the Walter 29/64" SST+ bit provides the reliability and speed required by professional tradespeople. It is an essential tool for any MRO toolkit, offering versatility across a wide range of materials including mild steel, aluminum, and non-ferrous metals.
