01D620 - Walter 12.00Mm Sst Drill Bit

Unmatched Durability for Stainless Steel Fabrication

For welders and fabricators, drilling through stainless steel is often one of the most frustrating parts of the job. Work hardening can destroy a standard bit in seconds, leading to downtime and wasted money. The Walter 01D620 12.00mm SST+ Drill Bit is the solution to these fabrication headaches. Formulated with a heavy-duty cobalt blend, this bit is specifically built to withstand the high temperatures generated when cutting hard metals. It bites into the material instantly and maintains its hardness even under extreme thermal stress, allowing you to drill through stainless plate, tube, and angle with confidence.

Precision is non-negotiable in welding preparation. The SST+ features a sophisticated point geometry that is self-centering. This is a game-changer when working with pipe or tubing, as it prevents the bit from "walking" or skating across the surface. You can place the tip exactly where you need the hole and start drilling immediately, often eliminating the need for center punching. This accuracy ensures that your fit-up remains tight and your fabrication tolerances are met every time.

The structural integrity of the bit is enhanced by its "High Flow" flute design and back-tapered body. As you drill, the unique flute shape rapidly ejects metal chips, preventing them from packing in the flutes. This is crucial for preventing heat buildup that causes stainless steel to work-harden. By keeping the cutting zone cooler, the bit cuts freely and requires less feed pressure from the operator. The bronze SST surface treatment further aids this process by reducing friction, allowing for smoother penetration and cleaner exit holes with fewer burrs to grind off later.

Whether you are installing fixtures, prepping for bolted connections, or fabricating custom machinery, the 12.00mm size is a versatile metric standard. The Walter SST+ is compatible with all standard drill chucks and is tough enough for impact drivers and high-torque cordless drills. Stop struggling with inferior bits that burn out halfway through the job. Upgrade to the Walter 01D620 and experience the difference that professional-grade tooling makes in your welding and fabrication projects.
