OVERVIEW

Precision Drilling with Walter SST Stub Drill Bits

The Walter 01J006 #6 SST Stub Drill represents the pinnacle of drilling technology for industrial fabrication and maintenance. Designed specifically to address the challenges of drilling through tough materials like stainless steel and thin-gauge sheet metal, this bit combines advanced metallurgy with superior geometric design. Unlike standard jobber-length bits that can flex and wander, the stub (or screw machine) length of this tool provides exceptional rigidity. This rigidity is crucial when working with portable drilling tools, as it significantly reduces the likelihood of bit breakage under side-load pressure, ensuring that your operations remain continuous and cost-effective.

At the core of the 01J006 is a high-performance Cobalt blend. This material composition allows the drill bit to withstand the extreme heat generated when drilling hard metals, maintaining its cutting edge far longer than high-speed steel alternatives. To further enhance performance, Walter has applied their proprietary bronze SST surface treatment. This specialized coating acts as a lubricant and heat shield, reducing friction between the bit and the workpiece. The result is a smoother drilling action, cleaner holes, and a dramatic extension of the tool's lifespan, even in the most demanding production environments.

Efficiency is key in any workshop, and the geometric features of this drill bit are engineered for speed. The heavy-duty split point design eliminates the need for pre-punching or pilot holes. It bites into the material immediately upon contact, preventing the "walking" effect common with standard chisel-point bits. The short flutes are optimized to eject chips rapidly while maintaining the structural integrity of the bit. Whether you are drilling out rivets, creating pilot holes for fasteners, or working on complex sheet metal assemblies, the Walter #6 SST Stub Drill delivers the precision and durability required by professional tradespeople.

Key Industrial Benefits:

  • Enhanced Rigidity: Short overall length prevents flexing and snapping.
  • Superior Heat Resistance: Cobalt blend thrives in high-temperature drilling applications.
  • Self-Centering: Split point geometry ensures accurate hole placement every time.

FAQ

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

Yes, absolutely. The Walter 01J006 is made from a cobalt blend specifically designed to withstand the high heat and abrasion associated with drilling stainless steel and other hard alloys.

Generally, no. The Walter SST Stub Drill features a split point geometry that is self-centering. It is designed to penetrate the material immediately upon contact without 'walking' or skating across the surface.

The bronze SST surface treatment helps to reduce friction between the bit and the workpiece. This lowers the drilling temperature, improves chip flow, and ultimately extends the life of the drill bit.

A #6 wire gauge drill bit has a diameter of approximately 0.2040 inches (5.18 mm). It is a specific size in the numbered drill bit series, often used for tapping or clearance holes for specific screw sizes.

Yes, the combination of the short, rigid stub design and the self-centering split point makes it excellent for drilling into round surfaces where longer bits might deflect or wander.

Sheet metal often causes standard bits to snag and snap as they break through the other side. The shorter flute length of a stub drill provides high rigidity, preventing the flexing that leads to breakage during breakthrough.
