01J017 - Walter SST+ Stub Drill Bit 17/64" Cobalt Blend

Walter SST Stub Drill Bit 17/64" – Precision for Sheet Metal

The Walter 01J017 SST Stub Drill Bit is a high-performance cutting tool designed specifically to address the challenges of drilling through thin gauge metals and tough alloys. Manufactured with a specialized cobalt blend, this drill bit withstands high temperatures and maintains its cutting edge far longer than standard high-speed steel bits. The 17/64-inch diameter is precise, making it an essential addition to any professional fabricator's toolkit.

One of the standout features of the SST Stub series is its geometry. The "stub" or screw machine length provides significantly more rigidity than jobber-length bits. This increased stiffness minimizes deflection and vibration, which is the leading cause of bit breakage. Furthermore, the 135-degree split point tip bites into the material immediately upon contact, eliminating the need for center punching and preventing the bit from "walking" across the surface of the metal.

Whether you are working with mild steel, non-ferrous metals, or demanding stainless steel sheets, the Walter SST Stub Drill delivers clean, round holes with efficiency. The exclusive bronze SST surface treatment further enhances performance by reducing friction and heat buildup, ensuring smooth operation even under heavy loads. This bit is compatible with both portable drills and stationary drill presses.
