01D542 - Walter 4.20Mm Sst Drill Bit

Walter SST+ 4.20mm Drill Bit: The Welder's Choice for Tough Metals

For welders and fabricators, drilling through stainless steel and hard alloys is a daily challenge that demands superior tooling. The Walter 01D542 SST+ Drill Bit (4.20mm) is engineered to turn this challenge into a simple task. Featuring a newly formulated cobalt blend, this bit is built to withstand the intense heat generated when drilling hard metals, ensuring that the cutting edge stays sharp longer than conventional bits. This means fewer bit changes and more time focused on fabrication and assembly.

The geometry of the SST+ bit is designed for speed and precision. The "high flow" flute design is a game-changer for clearing debris. As you drill, the flutes efficiently pull chips up and out of the hole, preventing clogging and overheating. This is particularly important when working with stainless steel, which tends to work-harden if the bit dwells or overheats. Additionally, the back tapered body reduces drag, allowing the bit to cut freely without grabbing or stalling your drill. This feature is invaluable when using portable power tools, providing a smoother, more controlled drilling experience.

Walter's exclusive bronze SST surface treatment adds another layer of performance. This specialized coating reduces friction, allowing the bit to penetrate material with less force. It also helps prevent the bit from welding to the material, a common issue when drilling aluminum or gummy stainless grades. The result is a clean, precise hole every time. Whether you are drilling pilot holes for fasteners, preparing surfaces for welding, or fabricating custom parts, the Walter SST+ provides the reliability and speed you need.

Stop struggling with dull bits that burn out halfway through the job. Upgrade to the Walter 01D542 and experience the difference that premium engineering makes. From mild steel to non-ferrous metals, this bit is versatile enough to handle all your drilling needs. Its robust construction ensures it can handle the rigors of the welding shop, making it an essential accessory for any serious metalworker.
