01D545 - Walter 4.50Mm Sst Drill Bit

Bite Through Stainless Steel Without the Struggle

If you have ever spent your day fighting to drill through stainless steel with a dull bit that wanders all over the workpiece, the Walter SST+ 4.50mm Drill Bit is the upgrade your toolbox needs. Designed for professional welders and fabricators, this bit is built to tackle the toughest metals without burning out. The secret lies in the cobalt blend material, which stands up to the intense heat generated when drilling hard alloys, keeping the cutting edge sharp long after standard bits have failed.

One of the standout features for daily use is the 135° split point. This aggressive tip bites into the metal immediately upon contact—even on curved surfaces like pipe or tubing—so you don't have to worry about the bit "walking" and scratching your finish. You can drill exactly where you mark, often without needing a center punch. The unique Bronze SST coating isn't just for looks; it acts as a shield against friction, helping the bit slide through the material smoothly.

The flute design is also optimized for speed. It pulls chips out of the hole rapidly, which keeps the bit cooler and prevents binding. Whether you are drilling out rivets, prepping for a tap, or fabricating a custom bracket, the Walter 01D545 delivers clean, precise holes with less pressure required from your drill. It works exceptionally well in portable hand drills, making it a favorite for on-site installs and repairs.
