OVERVIEW

Upgrade Your Mag Drill with Walter SST Core Cutters

Fabricators know that drilling large diameter holes in the field requires a cutter that can handle the heat. The Walter 05A202 SST Core Cut Annular Cutter is built to tackle the toughest jobs in the shop or on the job site. With a massive 2-1/8" diameter and a 1" depth of cut, this tool is designed to punch through plate and structural beams quickly and cleanly. What sets the Walter SST apart is its unique bronze surface treatment, which isn't just a coating—it's a performance enhancer that slicks the surface of the cutter to shed chips and reduce drag.

When you are drilling stainless steel or thick aluminum, chip welding and heat are your worst enemies. The SST Core Cut fights back with a high-tech surface that eliminates the microscopic rough spots found on standard bits. This means the cutter glides through the metal, requiring less force on the feed handle and putting less strain on your mag drill's motor. The fully ground flutes act like a conveyor belt for swarf, ejecting metal shavings rapidly so you don't have to stop and clear the hole. This efficiency translates directly to time saved per hole, which adds up quickly on large structural projects.

The 05A202 features a universal shank, making it a "plug-and-play" solution for almost any magnetic drill rig you have in your fleet. It eliminates the need for special adapters or specific brand loyalty regarding your power tools. From the modern tooth geometry that centers the bit instantly to the robust HSS construction that holds an edge hole after hole, this annular cutter is a reliable workhorse. Stop fighting with dull, overheating bits and switch to the smooth-cutting power of Walter SST technology for your next fabrication challenge.

Why Choose Walter SST?

Faster Cuts: Aggressive geometry removes material quickly.
Cooler Operation: Slick surface reduces friction heat.
Clean Finish: Leaves a burr-free hole ready for bolts.
Versatile: Works on Steel, Stainless, and Aluminum.

FAQ

This specific Walter SST Core Cut (05A202) has a diameter of 2-1/8 inches and a maximum depth of cut of 1 inch.

It features a universal shank, designed to fit the majority of magnetic drilling units and stationary machines available on the market.

Yes, the SST (Super Surface Treatment) and high-speed steel construction make it excellent for drilling stainless steel, as well as mild steel and aluminum.

Yes, annular cutters typically require a pilot pin to center the cut and eject the slug after drilling. The pin is usually sold separately or comes with the drill arbor.

The SST (bronze) treatment eliminates surface porosity on the cutter, which significantly reduces friction and heat generation, extending the tool's life.

Yes, like most high-quality HSS annular cutters, the Walter SST Core Cut can be resharpened to extend its service life.

The optimal RPM depends on the material being drilled (slower for stainless, faster for aluminum). Always consult the Walter speed chart for 2-1/8" cutters.
