Walter SST+ 1/8 Inch Cobalt Extension Drill Bit (6 Inch Length)

Reach Further with Walter SST+ Durability

Every welder knows the frustration of needing to drill a hole in a spot that a standard bit just can't reach. The Walter 1/8" SST+ Extension Drill Bit (SKU: 01F508) solves this problem with its extended 6-inch length, giving you the extra reach needed for deep assemblies, channel iron, or awkward fabrication angles. But this isn't just a long drill bit; it is a high-performance cutting tool built to withstand the rigors of the welding shop.

Drilling stainless steel can destroy lesser bits in seconds. That is why Walter engineered the SST+ line with a powerful cobalt blend. This advanced material resists the intense heat that hardens stainless steel, keeping the cutting edge sharp hole after hole. To further enhance performance, the bit features a special Bronze SST surface treatment. This slick coating helps chips slide out of the flutes easily and reduces friction, preventing the bit from binding or overheating. You get faster drilling speeds and less downtime changing out dull bits.

Accuracy is just as important as durability. This bit features a 135-degree split point tip that bites into the metal immediately. You won't have to worry about the bit wandering off your mark or scratching up the workpiece. It centers itself, allowing you to drill precise holes without a pilot hole or center punch. From mild steel brackets to aluminum fittings and stainless sheets, the Walter 01F508 is the reliable, heavy-duty extension bit that belongs in every fabricator's toolbox.
