Walter 36mm Carbide Tipped Annular Cutter - 30mm Depth

Precision Hole Cutting for Professional Welders

For welders and fabricators working on-site or in the shop, the Walter 36mm x 30mm Carbide Core Cut annular cutter is an essential tool for heavy-duty hole making. Unlike twist drills that require massive amounts of horsepower and physical force to push through thick metal, this annular cutter removes only the periphery of the hole, ejecting a solid slug. This core drilling method is far more efficient, requiring less energy and allowing for faster penetration rates. This specific model, with its 36mm diameter and 30mm depth of cut, is perfectly sized for a wide range of bolt holes, pass-throughs, and structural connections found in steel erection and equipment repair.

What sets the Walter 05F136 apart is its ability to handle the materials that usually destroy standard bits. If you work with stainless steel, cast iron, or hard facing, you know that HSS bits can burn up quickly. This cutter features extra-hard carbide inserts that slice through these tough metals with ease. The specialized flute design helps keep the cut cool by ejecting hot chips quickly, which is vital when you are out in the field without a flood coolant system (though paste or spray lubricant is always recommended). This durability means you spend less time sharpening or replacing bits and more time welding and fabricating.

Designed for use with magnetic drilling units, this cutter provides the stability needed for drilling on vertical beams or overhead assemblies. Its aggressive cutting action reduces the feed pressure required by the operator, reducing fatigue during long shifts. Whether you are retrofitting piping systems, repairing heavy earthmoving equipment, or fabricating custom structural frames, the Walter Carbide Core Cut delivers clean, burr-free holes that are ready for bolting or welding immediately. Invest in tooling that matches the quality of your craftsmanship with Walter's proven carbide technology.
