For welders and fabricators, time is money, and stopping to manually tap a hole with a wrench is a productivity killer. The Walter 7/16-14 UNC SST Power Tap (03B571) is designed to keep your workflow moving by allowing you to tap holes directly using your reversible portable drill. Built to withstand the harsh conditions of the welding shop and the job site, this tap is particularly effective on stainless steel, a material known for work-hardening and breaking lesser tools.
The secret to its durability lies in the SST surface treatment and robust geometry. Tapping stainless steel requires a tool that stays cool and cuts freely; the SST coating provides the necessary lubricity to slice through tough alloys without binding. This tap utilizes a "Power Tip" design that pushes metal chips out ahead of the tool. This is crucial for welders working on structural steel or plate, as it keeps the flutes clear and prevents the tap from jamming and snapping off inside the hole—a nightmare scenario that can ruin a nearly finished part.
Slippage is another common frustration when using round-shank taps in a hand drill. Walter has solved this with a secure three-flat shank that locks firmly into your drill’s chuck. This ensures that when the drill turns, the tap turns, delivering the torque needed to cut clean threads every time. The self-aligning feature also helps you start the hole straight without needing a drill press, which is ideal for repairs on large equipment or fixed structures where bringing the work to a machine isn't an option.
