Walter 8-32 NC HSS Bottoming Tap

Reliable Thread Repair and Fabrication

When you need to cut clean, accurate threads in your shop, the Walter 8-32 NC Bottoming Tap (03A083) is the tool for the job. Built by Walter Surface Technologies, a leader in industrial abrasives and tooling, this tap is made from heavy-duty High Speed Steel (HSS). Unlike cheaper alternatives, HSS taps resist heat and wear significantly better, allowing you to cut through mild steel, stainless steel, and aluminum without losing sharpness prematurely. This makes it an essential addition to any welder's or fabricator's toolbox.

This tap is a "Bottoming" tap, which means it has a very short taper at the end. It is specifically designed for threading "blind holes"—holes that don't go all the way through the metal. Because the cutting threads start almost immediately at the tip, you can thread right down to the bottom of the hole, ensuring maximum thread engagement for your bolts or screws. It is often used as the final step in the tapping process, following a taper or plug tap.

Don't let stripped threads or poor-quality tools slow down your project. The Walter 03A083 ensures you get the job done right the first time. Its hardened and tempered structure provides the strength needed to prevent snapping inside the hole, a nightmare scenario for any fabricator. Pair this tap with a quality cutting oil to ensure smooth operation and perfectly formed threads every time.
