    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Black/Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.

    Avoid clogs and dissipate heat with cobalt bits that last at least twice as long as high-speed steel. The flutes clear chips to improve coolant flow and prevent damage to the bit and the hole. They also speed up drilling since you don't have to stop to clear the bit manually.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.

    Carbide Rounded-Edge Square End Mills for Copy Milling

    Rounded-Edge

    Square Cut Style

    Replicate the shape of complex parts with these end mills. Also known as torus end mills, they have a rounded edge for precision contouring. These end mills are also used for slotting and pocketing cuts in mold and die making. Their 90° profile and rounded corners reduce flute breakage and chipping. All are center cutting, allowing plunge cuts into a surface.
    Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. A titanium aluminum silicon nitride (TiAlSiN) coating makes them extremely resistant to wear and diffusion because they have especially high hardness, even at high temperatures.
