Walter 13/16 Inch Carbide Tipped Annular Cutter 4 Inch Depth

Drill Deeper and Faster on the Job Site

For professional welders and fabricators, time is money, and nothing kills productivity faster than a burnt-out drill bit stuck halfway through a thick plate. The Walter 13/16" X 4" Carbide Core Cut is built to solve exactly that problem. If you are working with magnetic drills on structural steel, stainless tanks, or heavy cast iron machinery, this is the cutter you need in your arsenal. With a massive 4-inch cutting depth, this bit allows you to drill through thick columns, stacked plates, or heavy-wall pipe in a single pass, eliminating the need for flipping heavy workpieces or trying to line up holes from both sides.

The secret to this cutter's performance lies in its carbide tips. Standard steel bits struggle with the heat generated by drilling stainless steel, often dulling after just a few holes. This Walter cutter eats through stainless, tough alloys, and even rust-covered cast iron without losing its edge. This means fewer tool changes, less downtime, and a lower cost per hole in the long run. The aggressive cutting action requires less physical force from the operator, reducing fatigue during long days of fabrication. It is designed to cut clean, precise holes that are ready for bolting or welding immediately, often eliminating the need for secondary deburring or reaming.

Whether you are retrofitting steel beams in a high-rise or repairing heavy earth-moving equipment in the field, reliability is key. The Walter 05D813 is designed to handle the vibration and instability of on-site drilling. Its specialized flute design clears metal chips efficiently, preventing the bit from binding up deep in the hole. This is the heavy-duty solution for welders who demand tools that work as hard as they do. Stop fighting with dull HSS bits and upgrade to the industrial power of Walter's Carbide Core Cut for your toughest drilling challenges.
