    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 Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.

    Milwaukee Electric Rotary Hammers

    Image of Product. Front orientation. Drills. Milwaukee Electric Rotary Hammers.
    A powerful and durable hammer mechanism lets you drill deeper, larger holes in masonry and concrete in less time than with hammer drills. Also known as a SDS-Plus rotary hammer, this model is lightweight and ideal for overhead work and drilling smaller holes. Use with SDS-Plus drill bits. Note: SDS-Plus and SDS-Max bits are not interchangeable.
    Use the rotary-only mode for general purpose drilling and driving fasteners (requires a chuck adapter or a magnetic bit holder). In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. In the percussion-only mode, the tool provides only the hammering action. Use this mode when working with chisels and other masonry tools (see Chisels for Rotary Hammers).
    This model has a variable speed—the further you depress the trigger, the faster the speed.
    35 Chisel Lock Positions—A chisel lock allows you to choose from 35 chisel positions to match the angle of many surfaces.
    Built-In Safety Clutch—A built-in safety clutch protects you and the hammer if the bit gets stuck in your material.

    Spiral Flute

    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
    Spiral Flute—Since these reamers clear chips better than straight flutes, they leave holes with a smoother finish. They're better for holes with breaks in the surface, such as a keyway, because they cut continuously across the breaks instead of moving in and out.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Carbide-Tipped Tool Steel—Since these reamers retain a sharper, harder edge at higher temperatures than high-speed steel and cobalt steel, they can be used on hard materials, such as iron, hardened steel, and steel alloys. They aren't as brittle as solid carbide reamers, so they can be used in less rigid setups, such as a hand-held drill.
    Right-Hand Spiral—These reamers pull chips upward as they cut, so they're often used in blind holes.

    Straight Flute

    Unlike standard reamers, which are unusable once they become worn, these can be returned to their original size for finishing holes. After the reamer is worn down, tighten the set screw to expand the diameter, grind the reamer to its original size, and get back to work.
    These are not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The set screw should not be loosened.
    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
