1-9/16 Inch Carbide Tipped Annular Cutter 2 Inch Depth

Heavy-Duty Mag Drill Bit for Stainless and Structural Steel

For professional welders and fabricators, time on the job site is money, and nothing slows down a project like a dull drill bit fighting against a piece of stainless steel. The Walter 1-9/16" x 2" Carbide Core Cut (05D409) is the solution for drilling large diameter holes quickly and cleanly, even in the toughest materials. Whether you are working on a structural steel erection, modifying heavy machinery, or fabricating custom stainless vessels, this annular cutter is designed to cut through metal that would burn up a standard HSS bit in minutes. The carbide tips are incredibly hard, allowing you to plow through rust, scale, and hard alloys without losing your edge.

This cutter is built for use with magnetic drill presses, a staple tool for on-site fabrication. The 2-inch depth of cut gives you the versatility to drill through thick plates, stacked materials, or heavy-wall pipe in a single pass. One of the standout features for welders is the clean finish this cutter produces. Because it cuts a ring of metal rather than turning the entire hole into chips, it requires less horsepower and creates a burr-free hole that is ready for bolting or welding immediately. This eliminates the tedious step of grinding or filing the hole after drilling, saving you valuable time and effort.

The design of the Walter Carbide Core Cut also helps when you aren't working on perfect, flat stock. If you need to drill into a pipe or a curved surface, the aggressive cutting action and stable body design help the bit bite in without walking, ensuring your holes are exactly where you marked them. It handles the heat of drilling stainless steel exceptionally well, preventing work-hardening of the material around the hole. If your daily work involves heavy fabrication where reliability and speed are non-negotiable, upgrading to a carbide-tipped cutter like this Walter unit is a game-changer for your toolkit.
