OVERVIEW

Tough Bits for Tough Jobs

Welders and fabricators know that drilling sheet metal with a hand drill can be frustrating with standard bits that snap under pressure. The Walter #4 SST Stub Drill solves this problem with its heavy-duty, short-length design. By reducing the length of the bit, Walter has created a tool with exceptional core strength and rigidity. This means you can apply the necessary feed pressure to cut through steel without worrying about the bit flexing and snapping off in the middle of a job. It is the ultimate solution for drilling out rivets, installing fasteners, or creating pilot holes in body panels and enclosures.

This #4 size bit (0.2090") is manufactured with a robust cobalt blend, giving it the hardness required to tackle stainless steel and other hard metals that would quickly dull a standard high-speed steel bit. The bronze surface treatment aids in chip evacuation and reduces heat, keeping the cutting edge sharp for longer. For welders working in the field or the shop, reliability is key, and the SST Stub Drill delivers reliable performance hole after hole.

Efficiency is critical in any fabrication project. The SST Stub Drill features a quick-starting split point that bites into the metal instantly. You won't waste time struggling to keep the drill steady or repairing scratches caused by a wandering bit. From mild steel to aluminum and stainless, this versatile bit handles it all. Add the Walter 01J004 to your toolbox for a drilling solution that works as hard as you do.

FAQ

A stub drill (or screw machine length drill) has a shorter flute and overall length compared to a standard jobber drill. This makes it more rigid and less likely to break, which is ideal for drilling sheet metal or using hand drills.

A #4 wire gauge drill bit has a diameter of 0.2090 inches.

Yes, the Walter SST Stub Drill is made with a cobalt blend specifically designed to withstand the heat and hardness of drilling stainless steel.

Generally, no. The split point design allows the bit to self-center and start drilling immediately without walking, often eliminating the need for a center punch.

The bronze SST treatment helps reduce friction between the bit and the workpiece, which lowers heat generation and helps extend the life of the tool.

Yes, it is suitable for non-ferrous metals like aluminum, as well as mild and stainless steel.

Sheet metal can cause longer bits to flex and snap as they break through the thin material. The shorter, stiffer stub drill resists this flexing for a cleaner hole and longer tool life.

It is designed for use with all portable power drills (corded or cordless) as well as stationary drill presses.
