01K014 - Walter 01K014 7/32 Inch Cobalt SST+ Double-Ended Stub Drill Bit

Precision Engineering with Walter SST+ Technology

The Walter 01K014 7/32" SST+ Double-Ended Stub Drill Bit represents the pinnacle of drilling efficiency for industrial applications. Engineered to address the common failure points of standard drilling tools, this bit utilizes a proprietary Cobalt High-Speed Steel (HSS) alloy. This advanced material composition significantly enhances heat resistance, allowing the bit to maintain its cutting edge even under the high thermal loads generated when drilling hard metals like stainless steel. Unlike conventional black oxide bits that dull rapidly, the SST+ alloy ensures a prolonged service life, reducing tooling costs and downtime.

A key feature of the 01K014 is its double-ended design. By incorporating cutting geometry on both ends of the stub length shaft, Walter effectively doubles the lifespan of a single unit. When one end eventually wears down, the operator can simply flip the bit to utilize a fresh cutting edge immediately. This design is particularly advantageous in high-volume production environments where efficiency is paramount. The stub length itself contributes to the tool's performance by providing superior rigidity compared to jobber-length bits, minimizing the deflection and vibration that often lead to breakage.

The geometry of the bit is equally impressive, featuring a self-centering point that engages the material instantly upon contact. This eliminates the need for pre-punching and prevents the bit from "walking" across the workpiece surface, ensuring precise hole placement every time. Furthermore, the "High Flow" flute design is optimized to evacuate chips rapidly, preventing clogging and heat buildup. Whether used in aeronautical maintenance, automotive manufacturing, or general fabrication, the Walter 01K014 delivers consistent, high-quality results in thin-gauge metals and tubular stock.
