01A027A - Walter 27/64" SST+ Cobalt Jobber Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A027A 27/64" SST Jobber Drill Bit represents the pinnacle of drilling performance for industrial professionals. Engineered with a premium cobalt blend, this bit is designed to withstand high temperatures and abrasive materials, ensuring a longer service life compared to standard high-speed steel bits. The core of its performance lies in the exclusive "Speed Tip," a self-centering point that engages the material immediately upon contact. This feature eliminates the common issue of bit walking, allowing for precise hole placement without the need for a center punch or pilot hole, even on curved surfaces.

One of the standout features of this model is the proprietary Quick Shank. Designed to address the frustration of spinning bits, the Quick Shank ensures a positive lock in both keyed and keyless chucks. This secure grip translates to efficient torque transfer, making it particularly effective for cordless power tools. By reducing slippage and friction, the bit allows users to drill more holes per battery charge, significantly boosting productivity on the job site. The back-tapered body further enhances efficiency by reducing sidewall friction, preventing the bit from binding or overheating during deep drilling operations.

Durability is woven into every aspect of the Walter SST drill bit. The heavy-duty, fully ground body construction provides structural integrity, while the special bronze SST surface treatment aids in chip evacuation and heat dissipation. Whether you are working with mild steel, aluminum, or thin gauge sheet metal, this bit delivers clean, round holes with minimal burring. It is specifically optimized for drilling through multiple layers of metal, making it an indispensable tool for HVAC, automotive, and general fabrication applications where precision and speed are paramount.
