    Quick-Change Hex Drill-Bit Countersinks for Wood and Plastic

    Switch bits instead of tools to simplify jobs. These snap directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. You can slide the countersink up and down the drill bit and then secure it with a set screw, so one tool will drill countersunk holes for screws of different lengths. These countersinks cut a smooth and even finish in wood and plastic on the first pass.

    Image of Product. Side1 orientation. Drill Taps. Impact Wrench Drill Taps.
    Drill and thread holes in a single fluid step that’s 15 times faster than by hand. Made with an oversized shank and hardened high-speed steel, these drill taps are built to handle the high torque of your impact wrench to cut material quickly. A built-in pilot starts the hole while the taper chamfer gradually engages material for clean, accurate threads. Your wrench’s rapid hammering helps break and clear chips as you cut, so you don’t need to pause and reverse. This also means these drill taps are less likely to jam on chips and snap. They’re a great choice for quickly preparing threaded through holes in thin materials.
    You’ll need a VersaDrive chuck (sold separately) to install these drill taps into your impact wrench. You can also get chucks for impact drivers (sold separately).
    Titanium Nitride (TiN)-Coated Hardened High-Speed Steel—Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.
    Spiral Flute—Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.

    Roughing High-Speed Steel Square End Mills

    Image of Product. Front orientation. End Mills. Roughing High-Speed Steel Square End Mills, 4 Flutes.

    4 Flutes

    Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds. They are high-speed steel for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. Their square end makes them good for milling square slots and edges.
    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.
    Noncenter Cutting—Noncenter-cutting end mills are for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

    Carbide-Tipped T-Slot End Mills

    Image of ProductInUse. Front orientation. End Mills. Carbide-Tipped T-Slot End Mills.
    Image of Product. Front orientation. Contains Annotated. Carbide-Tipped T-Slot End Mills.
    Made of carbide-tipped high-speed steel, these end mills provide a sharper, harder edge at high temperatures than plain high-speed steel. Because they aren’t as brittle as solid carbide, they can be used in less rigid setups, such as manual milling machines. They're often used to create slots in machine tool tables, indexing tables, and other workholding surfaces.
    Uncoated—Use uncoated end mills for general purpose milling and short production runs. They stay sharper than coated end mills when used on soft materials like aluminum, leaving a better finish.
    Titanium Nitride (TiN) Coated—Titanium nitride (TiN)-coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
    Titanium Carbon Nitride (TiCN) Coated—Titanium carbon nitride (TiCN)-coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
    Aluminum Titanium Nitride (AlTiN) Coated—Aluminum titanium nitride (AlTiN)-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.

    Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds. 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 end makes them good for milling square slots and edges. All are noncenter-cutting for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.
    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.
    Uncoated Cobalt Steel—Use uncoated end mills for general purpose milling and short production runs.
    Titanium Carbon Nitride (TiCN)-Coated Cobalt Steel—Titanium carbon nitride (TiCN)-coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills.
    Coarse Pitch—Coarse-pitch end mills create large chips for better performance on softer metal, such as aluminum, brass, bronze, and carbon steel.
    Fine Pitch—Fine-pitch end mills last longer than coarse-pitch end mills and produce smaller chips for better performance on harder metal, such as iron, hardened steel, titanium, and tool steel.
    Flute Pitch—Flute pitch indicates the size of the serrations on a roughing end mill.
