OVERVIEW

High-Performance Drilling for Industrial Fabrication

The Walter 5/32" SST Double-End Stub Drill (01K010) represents the pinnacle of efficiency for industrial drilling operations involving thin materials and sheet metal. Engineered by Walter Surface Technologies, this tool is designed to address the common failure points of standard drill bits in high-throughput environments. By utilizing a proprietary Cobalt HSS alloy blend, this bit delivers exceptional hardness and heat resistance, far surpassing the capabilities of standard black oxide alternatives.

One of the standout features of this model is its SST surface treatment. This specialized coating drastically increases lubricity at the cutting edge, reducing friction and heat buildup—the primary enemies of drill bit longevity. Combined with Walter's "High Flow" flute geometry, the bit evacuates chips rapidly, preventing clogging and ensuring a clean, precise hole every time. The stub length design adds critical rigidity, minimizing the flex that often leads to breakage in longer bits, making it an ideal choice for CNC operations or handheld drilling where stability is paramount.

Efficiency is further maximized by the double-ended design. When one side eventually dulls after extensive use, the operator can simply flip the bit to utilize a fresh cutting edge, effectively doubling the tool's lifespan and reducing inventory costs. The self-centering point geometry ensures immediate engagement with the material, eliminating the walking effect and the need for pre-punching, which streamlines the fabrication workflow significantly.

Key Industrial Benefits

  • Extended Tool Life: Cobalt blend and double-ended design provide superior longevity.
  • Precision Geometry: Self-centering point ensures accuracy without pilot holes.
  • Optimized for Thin Metal: Specifically engineered for sheet metal and rivet work.

FAQ

A double-ended drill bit offers two cutting ends on a single tool. When one end becomes dull, you can simply flip the bit around and use the other end, effectively doubling the life of the tool.

This drill bit is designed for all types of metals, including mild steel, stainless steel, and aluminum. It is particularly effective on sheet metal and thin gauge materials.

The SST surface treatment increases the lubricity of the drill bit. This reduces friction during drilling, which in turn lowers heat buildup and extends the life of the cutting edge.

No, the Walter 01K010 features a self-centering point that prevents the bit from 'walking' or wandering across the surface, allowing you to start drilling immediately without a center punch.

This is a 'stub' drill bit. The shorter length provides greater rigidity and strength, reducing the likelihood of the bit snapping or flexing when pressure is applied.

Yes, the 5/32" size and stubby, rigid design make it an excellent choice for drilling out rivets in automotive and fabrication applications.

The diameter of this specific drill bit is 5/32 of an inch.

It features a 'High Flow' flute design which is engineered to evacuate chips more efficiently than standard designs, allowing for faster drilling speeds.
