The flutes spiral in the opposite direction of other bits and stay sharp longer than high-speed steel. They’re primarily used to remove stripped screws. Choose a bit that’s slightly smaller than the diameter of the screw’s head. Set your power tool to rotate in reverse. Slowly drill in the center of the screw head, maintaining constant pressure. As the bit penetrates, it will catch onto the screw and reverse it out of the hole. If the screw is badly stripped, you might need to punch a starter hole. Also known as reverse-flute bits.

Speed up jobs using high torque to drill multiple hole sizes with just one bit. Made with an oversized shank and hardened high-speed steel, these bits are built to handle the power of your impact wrench without snapping, even in large holes and hard materials such as stainless steel. Since your wrench absorbs kickback, it won’t fight you if the bit snags, reducing wrist strain and fatigue during long jobs.

The split point starts cutting on contact, so you don’t need to drill a pilot hole. The steps have progressively larger diameters—the deeper you drill, the bigger the hole. Count the steps as you drill to achieve the proper size. These bits also deburr as they cut, so they’re often used for thin materials such as sheet metal and plastic panels.

You’ll need a VersaDrive chuck (sold separately) to install these bits into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these bits directly into a _1/2" chuck on a standard power drill.

When one end wears out, switch to the opposite end for two times the life of a standard high-speed steel end mill. Made of high-speed steel, these end mills are for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. Their square ends make them good for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.

End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.

When one end wears out, switch to the opposite end for two times the life of a standard cobalt steel end mill. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. Their square ends make them good for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.

Use these versatile end mills for milling in most material, including aluminum, brass, bronze, iron, and steel. They have scooped corners for rounding the sharp edges of your workpiece.
