Walter SL-5 Double Cut Carbide Burr 6-Inch Extended Shank

Reach Deep and Grind Fast

Every welder knows the frustration of spotting a defect or a rough weld in a spot that your standard grinder just can't touch. That's where the Walter 01V652 Carbide Burr comes into play. This isn't your average rotary file; it's a problem solver designed with a 6-inch extended shank. This extra length gives you the reach you need to clean up root passes inside pipes, smooth out internal corners, or prep surfaces deep inside fabricated assemblies without struggling or compromising your angle of attack.

The SL-5 shape (Taper with Radius End) is one of the most useful profiles for welding applications. The tapered nose allows you to work into tight V-grooves and corners, while the radiused tip prevents gouging, helping you blend welds smoothly into the base metal. Because it features a Double Cut design, this burr eats through metal aggressively but leaves a surprisingly smooth finish. The cross-cut teeth break the metal into tiny chips rather than long, dangerous slivers. This means less clogging, less heat buildup, and much better control—the tool won't try to "climb" or jump out of the cut like a single-cut burr might.

Durability is key when you are grinding down hard welds or stainless steel. Walter uses premium tungsten carbide that holds its edge longer than standard high-speed steel bits. You can run this burr hot and hard, and it will keep cutting. It is compatible with any standard pneumatic or electric die grinder with a 1/4" collet. Whether you are working on structural steel, fixing a stainless tank, or doing custom fabrication, keeping the 01V652 in your toolbox ensures you are never stuck unable to reach a critical grind.

Stop fighting with tools that are too short for the job. Upgrade to the Walter 01V652 and experience the difference that a high-quality, balanced, and extended-reach carbide burr makes in your daily grind. It’s built to handle the vibration, speed, and pressure of real-world welding environments.
