01A019A - Walter SST 19/64-Inch Cobalt Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A019A 19/64" SST Jobber Drill Bit represents the pinnacle of drilling efficiency for industrial maintenance and fabrication professionals. Engineered with a proprietary high-quality cobalt blend, this tool is designed to withstand the extreme thermal stresses generated during heavy-duty drilling applications. Unlike standard high-speed steel bits that soften and dull rapidly under heat, the SST's cobalt composition maintains hardness at elevated temperatures, significantly extending the service life of the cutting edge. This makes it an exceptional choice for MRO environments where tool longevity and reliability are paramount to maintaining workflow efficiency.

One of the standout features of this drill bit is the exclusive Quick Shank technology. In high-torque applications, standard round shanks often slip within the chuck, damaging both the bit and the tool while halting progress. The Quick Shank features a multi-flat design that locks securely into both keyed and keyless chucks, ensuring positive drive transmission. This feature is particularly beneficial when utilizing cordless power tools, as it ensures that every ounce of motor torque is transferred directly to the cutting face, thereby maximizing the number of holes drilled per battery charge. This efficiency translates directly to operational cost savings and reduced downtime for battery swaps.

Precision geometry is at the core of the SST's performance. The bit features a self-centering "Speed Tip" that bites into the material instantly upon contact. This eliminates the need for pre-punching or pilot holes, even when drilling on curved surfaces such as pipes or tubing. The body of the bit is back-tapered, a design choice that reduces surface contact between the bit and the hole walls, minimizing friction and heat buildup. Combined with the special bronze SST surface treatment, this tool offers superior chip evacuation and smooth cutting action in mild steel, aluminum, and thin gauge sheet metals.

Key Technical Benefits:

• Cobalt Blend Substrate: Provides exceptional heat resistance and wear life.
• Quick Shank Architecture: Guarantees zero slippage in chucks for maximum torque transfer.
• Precision Ground Flutes: Ensures efficient chip removal and hole accuracy.
• Versatile Application: Excellent performance on non-ferrous metals and mild steel assemblies.
