Magnetic Drill Press Bit: OSCARBIDE 7/8x1 Annular Cutter

OSCARBIDE, a brand specialized 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 finish their work more effectively.

The OSCARBIDE Annular Cutter, a standout product, is made with premium high-speed steel (HSS) material, offering longer service life and high heat resistance. The unique design of the annular cutters allows for time-saving and energy-efficient drilling. These cutters have fewer teeth and less wear, enabling higher or faster cutting speeds and feed rates, while requiring less thrust and energy to drill through the material. The resulting holes are more finished, precise, and accurate.

The easy-to-use annular cutters excel at making holes at awkward angles, and they can be easily re-sharpened on a grinding machine and re-used for drilling. Re-grinding can be done until the desired cutting length is available on the annular cutter. These cutters eliminate the need for pre-step drilling, and holes can be cut in as little as 15 seconds.

The OSCARBIDE Annular Cutter features a 3/4-inch Weldon shank, a 1-inch cutting depth, and a 7/8-inch cutting diameter, with 2 flats and a 1/4-inch x 3-inch (6.34 x 77 mm) pilot pin size. These cutters are best used with a drill press or magnetic drilling machine, as they can handle the high torque forces and lower RPMs compared to other types of drills.

The OSCARBIDE Annular Cutters are suitable for working with both ferrous and non-ferrous metals, cast iron, stainless steel, aluminum, copper, and plastic, as well as wood, in either plate or pipe form. They are particularly useful in various processing fields, such as engineering, rail transit, bridges, ships, machinery manufacturing, and aerospace, especially for mild and structural steel.

During the drilling process, the pilot pin will retract into the cutter, allowing lubrication to reduce heat gain in the slug. It is essential to insert the ejector pin inside the annular cutter and use lubricant or coolant to ensure the longevity and optimal performance of the cutters. HSS annular cutters require cutting oil, not coolant.

In summary, the OSCARBIDE Annular Bits offer a significant advantage over traditional drill bits, drilling large holes up to ten times faster, with a thin-walled and dual alternating teeth design for efficient and aggressive cutting. These cutters can drill much larger holes with less force and time, producing burr-free and smooth holes, resulting in less scrap and wastage of material, higher accuracy, and better endurance.
