01J016 - Walter SST+ Stub Drill Bit, Wire Gauge #16, Cobalt Blend, Split Point

Precision Engineering: Walter #16 SST Stub Drill Bit

The Walter #16 SST Stub Drill Bit (SKU: 01J016) represents the pinnacle of drilling efficiency for industrial applications requiring high precision and durability. Designed specifically for the challenges of drilling sheet metal and hard alloys, this bit features a "stub" or screw machine length. This shortened geometry significantly reduces the torsional stress on the bit, providing superior rigidity compared to standard jobber-length bits. For professionals working with thin-gauge materials or utilizing portable drilling equipment, this added stiffness translates directly to cleaner holes, tighter tolerances, and a drastic reduction in snapped bits.

At the core of this tool is a high-quality cobalt blend. Unlike standard high-speed steel (HSS), the cobalt infusion grants the bit exceptional heat resistance, allowing it to maintain its cutting edge even when drilling through work-hardening materials like stainless steel. The bit is finished with Walter's proprietary Bronze SST surface treatment, which not only enhances surface hardness but also improves lubricity, facilitating smooth chip evacuation and reducing heat buildup during operation. This combination of metallurgy and surface science ensures that the Walter #16 SST Stub Drill delivers consistent performance over a significantly longer service life.

Efficiency is further maximized by the advanced split point design. This self-centering geometry engages the material immediately upon contact, eliminating the "walking" or skating effect common with standard chisel-point bits. This means you can drill precisely where you intend without the extra step of using a center punch. With a diameter corresponding to wire gauge #16 (0.1770 inches), this bit is an essential component for fabrication shops, maintenance departments, and any industrial setting where reliability and precision are non-negotiable.
