OVERVIEW

High-Performance Drilling with Walter SST Stub Drill Bits

Experience the difference that precision engineering makes with the Walter #23 SST Stub Drill Bit. Designed to tackle the most common frustrations associated with drilling metal—such as bit breakage and walking—this tool is a game-changer for maintenance professionals and fabricators alike. The "Stub" designation refers to its screw machine length; by shortening the overall length and the flutes, Walter has created a drill bit that is significantly more rigid than standard jobber bits. This increased stiffness allows you to apply the necessary pressure to cut through tough materials without the bit flexing or snapping, a common occurrence with smaller diameter bits.

The Walter 01J023 is crafted from a specialized cobalt blend material. Unlike standard high-speed steel (HSS), cobalt alloys possess superior heat resistance, known as "hot hardness." This makes the SST Stub Drill particularly effective when drilling stainless steel, a material that tends to work-harden and generate immense heat during machining. The addition of a unique bronze SST surface treatment further enhances performance by reducing friction and facilitating smoother chip evacuation, keeping the cutting edge cooler for longer.

One of the standout features of this drill bit is its self-centering split point geometry. On slick surfaces like sheet metal or rounded pipes, standard bits often wander before they bite. The Walter SST point centers immediately, ensuring your hole is exactly where you marked it. Whether you are drilling out rivets, working on auto body panels, or fabricating stainless steel enclosures, this drill bit delivers speed, accuracy, and durability. It is the reliable choice for portable drilling applications where stability and longevity are paramount.

Key Benefits:

  • Unmatched Rigidity: Short design prevents flexing and breakage.
  • Heat Resistance: Cobalt blend withstands high temperatures generated by stainless steel.
  • Precision Starting: Split point prevents walking for accurate hole placement.
  • Versatility: Excellent for mild steel, aluminum, and thin gauge sheet metal.

FAQ

A stub drill, also known as a screw machine drill, has a shorter overall length and shorter flutes compared to a standard jobber drill. This shorter design makes the bit much more rigid, reducing the chance of breakage and deflection, especially when applying heavy pressure.

The Walter 01J023 is manufactured from a premium cobalt blend. This material offers superior heat resistance and hardness compared to standard High-Speed Steel (HSS), making it ideal for drilling tough metals like stainless steel.

A #23 wire gauge drill bit has a diameter of 0.1540 inches, which is approximately 3.91 millimeters.

Yes, the Walter SST Stub Drill is specifically designed for stainless steel. Its cobalt blend construction and bronze surface treatment allow it to withstand the high heat generated when drilling hard alloys.

Generally, no. The Walter SST drill bits feature a split point geometry that is self-centering. This design prevents the bit from 'walking' or skating across the surface when you start drilling.

The bronze SST treatment helps to reduce friction between the bit and the workpiece. This lowers the drilling temperature, prevents chips from welding to the flutes, and extends the overall life of the tool.

Yes, it is excellent for hand drills. The shorter 'stub' length provides greater stability and reduces the likelihood of snapping the bit if your hand wobbles slightly during operation.

Yes, the Walter SST Stub Drill is versatile and performs well on non-ferrous metals like aluminum, as well as mild steel and stainless steel.
