Walter ICECUT 9/16" x 2" Annular Cutter with AICrN Coating

High-Performance Core Drilling for Fabricators

When you are out in the field or on the shop floor, you need a magnetic drill bit that cuts fast and doesn't burn out halfway through a beam. The Walter 05B309 ICECUT Annular Cutter (9/16" x 2") is built to handle the toughest drilling jobs in the welding and fabrication industry. This isn't just another standard high-speed steel bit; it is a high-performance tool coated with a specialized Aluminum Chromium Nitride (AICrN) layer. This grey coating is the secret to the cutter's incredible endurance, allowing it to cut through stainless steel and structural steel without overheating.

For welders, time is money. The ICECUT design allows for faster feed rates and cleaner holes, reducing the need for secondary deburring operations. The 2-inch depth of cut provides ample reach for drilling through thick plates, pipe, and tubing. One of the standout features for daily use is the universal shank. You don't need to worry about whether this bit will fit your mag drill; the universal shank is designed to lock securely into almost all major brands of magnetic drilling units. This versatility means you can keep fewer variations of bits in your truck box while still being prepared for any job.

The 05B309 is also designed to be forgiving in less-than-perfect conditions. While we always recommend using a high-quality cutting fluid or paste to extend tool life, the heat-resistant AICrN coating provides a safety buffer if you are drilling in a position where constant lubrication is tricky. The extra-large flutes help clear chips out of the hole quickly, preventing the bit from binding up. If you are fabricating structural steel, modifying truck frames, or installing equipment that requires precise 9/16" holes, the Walter ICECUT is the reliable choice that keeps your production moving.
