Walter SST Core Drill Bit 1-5/8 Inch x 1 Inch Depth

Maximize Your Mag Drill's Potential

When you are out in the field or on the shop floor, time is money, and the Walter 05A110 SST Core Cut Annular Cutter is built to save you both. This 1-5/8" x 1" cutter is the welder's choice for creating large, clean holes in a single pass. Unlike traditional twist drills that require step-drilling and massive amounts of pressure, this annular cutter removes only the periphery of the hole, ejecting a solid slug. This method requires far less energy and allows for much faster penetration rates, letting you move on to the next hole in record time.

The secret to its performance lies in the special bronze SST surface treatment. If you have ever struggled with bits burning up when drilling stainless steel or aluminum, you will appreciate the difference this coating makes. It acts as a lubricant barrier, preventing the metal chips from welding to the cutting teeth—a common issue known as galling. This means your cutter stays sharper for longer, even when you are pushing it hard on a deadline. The 1-inch depth of cut is perfect for standard plate and structural tubing applications commonly found in welding fabrication.

Compatibility is never an issue with the Walter SST line. The universal shank design slides easily into almost any magnetic drill press on the market, securing firmly for safe, wobble-free drilling. The geometry of the teeth is designed to be aggressive yet stable, reducing chatter and ensuring that the hole you drill is perfectly round and true to size. This precision is critical when you are prepping holes for bolted connections where tolerances are tight.

Stop fighting with dull bits and overheated drills. Upgrade to the Walter 05A110 and experience the smooth, effortless cutting action that professional fabricators rely on. Whether you are working on a bridge, a truck frame, or a custom fabrication project, this core cutter gives you the edge you need to get the job done right the first time.
