03A564 - Walter 6-40 UNF High-Performance Power Tap for Stainless Steel

Precision Threading for Industrial Fabrication

The Walter 6-40 UNF SST Power Tap (03A564) represents a significant leap in threading technology for maintenance, repair, and operations (MRO) environments. Designed to bridge the gap between the precision of traditional hand tapping and the speed of modern power tools, this accessory is engineered specifically for use with reversible portable drills. In industrial settings where stainless steel and tough alloys are commonplace, standard taps often fail due to heat buildup and chip clogging. Walter Surface Technologies has addressed these challenges with their proprietary SST surface treatment, which enhances lubricity at the cutting edge, reducing friction and extending the lifespan of the tool even under high-torque conditions.

One of the standout features of this power tap is its Power Tip geometry. This design element serves a dual purpose: it acts as a pilot to align the tap perfectly with the hole axis, ensuring straight threads every time, and it aggressively ejects chips ahead of the cutting action. This "spiral point" style functionality makes it the ideal choice for through-hole applications, as it prevents the accumulation of swarf within the flutes that can lead to tap breakage. The structural integrity of the tap is further reinforced by a long, resistant shank, allowing operators to reach into deeper cavities without compromising stability.

Slippage in the drill chuck is a common frustration when using round-shank tools for high-torque applications like tapping. The Walter 03A564 eliminates this issue with a precision-ground three-flat shank. This design ensures a positive lock within the drill chuck, transmitting maximum torque to the workpiece without the tool spinning inside the jaws. Whether working with aluminum, mild steel, or work-hardening stainless steel, this power tap delivers consistent, high-quality threads with a fraction of the effort required by manual methods.
