Walter SST+ #37 Cobalt Stub Drill Bit for Stainless Steel

Walter #37 SST Stub Drill Bit: The Solution for Tough Metals

Tired of snapping drill bits when working on stainless steel or trying to drill out spot welds? The Walter #37 SST Stub Drill (01J037) is the heavy-duty solution your shop needs. Built with a robust cobalt blend, these bits are designed to withstand the high temperatures generated when drilling hard metals, maintaining their cutting edge far longer than standard high-speed steel bits. The 'stub' length is the secret weapon here; by shortening the flute and overall length, Walter has created a bit that is incredibly rigid. This stiffness allows you to apply the necessary pressure to cut through tough alloys without the bit flexing or snapping off.

Precision is key in fabrication, and the Walter SST Stub Drill delivers. It features a 135-degree split point tip that prevents wandering. You can place the tip exactly where you need the hole and start drilling instantly—no center punching required. This is especially valuable when working on curved surfaces or polished sheet metal where a slipping bit could ruin the finish. The specialized bronze surface treatment helps shed chips and reduce heat, ensuring smooth operation and clean holes.

Applications:

• Stainless Steel: Cuts through 300 and 400 series stainless with ease.
• Sheet Metal: Short length prevents flexing for rounder, more accurate holes.
• Auto Body: Excellent for drilling out spot welds due to high rigidity.
• General Fabrication: Reliable performance on mild steel and aluminum.
