Annular Cutter: This specialized tool is designed to cut only the periphery of a hole, ejecting the remaining center as a slug. It produces accurate, burr-free holes to close tolerances without pre-drilling or step drilling. Best used with a drill press or magnetic drilling machine, these cutters can be easily used with light-duty drilling machines or portable magnetic base drilling machines.

Tungsten Carbide Tipped (TCT) Annular Cutters: These cutters have tungsten carbide tips, a very hard material suitable for cutting through tougher materials. TCT annular cutters are more expensive than High-Speed Steel (HSS) annular cutters, but they are faster and more efficient at making larger holes. The teeth on TCT annular cutters are harder than HSS, allowing them to cut more difficult materials, such as HARDOX steel, stainless steels, high-tensile strength steel, structural steel, and cast iron, including railway tracks. They are less susceptible to breakage than HSS cutters, especially in larger diameters and lengths.

The biggest advantage of hard-coated annular cutters is that they are faster and very good for cutting larger diameters on hard materials. These annular cutters are popularly used to drill materials like corroded or weathered material, structural and stainless steel. Carbide annular cutters fit various magnetic drills and presses, and can also be used with machine tools such as mills and large drill presses with tool holders.

Attention: During the drilling process, the pilot pin will retract into the cutter, allowing lubrication to reduce heat gain in the slug. It is important to insert the ejector pin inside the annular cutter and never use an annular cutter without an ejector pin. Using lubricant or coolant with any type of annular cutter is a must, as it helps extend the life of the cutters.
