OSCARBIDE Carbide TCT Annular Cutter Set for Magnetic Drill Press

OSCARBIDE specializes in selling high-quality lathe turning tools, boring bars, annular cutters, indexable end mills, carbide inserts, end mills, planer blades, and other metal cutting tools. The company serves metalworking and woodworking customers, providing them with reliable and quality products at better rates, helping machinists to complete their work more effectively.

The brand's Annular Cutter product line is particularly noteworthy. Tungsten carbide-tipped (TCT) annular cutters have tungsten carbide on their tips, making them a highly durable option suitable for cutting through tougher materials. TCT annular cutters are more expensive than high-speed steel (HSS) annular cutters but are faster and more efficient at creating larger holes.

Annular Cutters cut only the periphery of the hole, ejecting the remaining center as a slug. This process produces accurate, burr-free holes to close tolerances without pre-drilling or step drilling. These cutters are best used with a drill press or magnetic drilling machine, as their stability can withstand the high torque forces created by the drill bit and lower RPMs compared to other drill types. They can also be easily used with light-duty drilling machines or portable magnetic base drilling machines.

TCT annular cutters excel at cutting harder materials with ease, especially for boring larger diameter holes. In contrast, HSS annular cutters are more often used for drilling softer materials and smaller diameter hole sizes. 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.

Annular Cutters can be used to work with both ferrous and non-ferrous metals, cast iron, stainless steel, aluminum, copper, and plastic, as well as wood. They are particularly well-suited for making holes in pipes and tubes without dimpling and deburring. These cutters find applications in various processing fields, including engineering, rail transit, bridges, ships, machinery manufacturing, and aerospace.

During the drilling process, the pilot pin will retract into the cutter, allowing lubrication to reduce heat buildup in the slug. It is essential 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 proper lubrication and coolant delivery can extend the life of the cutters. HSS annular cutters specifically require cutting oil, not coolant.

OSCARBIDE offers a range of Annular Cutters Sets in various configurations, including 8-piece and 13-piece sets, catering to different cutting diameter and depth requirements. Customers can choose from these options based on their specific needs and applications.
