Nonsparking Drill Bits

Drill safely in flammable environments. Made of Factory Mutual (FM) approved beryllium copper, these bits won’t create sparks that could ignite if they made contact with combustible vapors or residues. These drill bits help you meet OSHA requirements in areas such as mines, refineries, and chemical plants where flammable materials are present.
Do not use these bits in direct contact with acetylene. Dust from beryllium copper can be toxic, so don't grind or sharpen them.

Hex-Shank Combination Drill Bit/Tap Sets for Drills and Screwdrivers

Drill and tap holes in a range of diameters. With a drill bit point to drive into the workpiece, these tools can drill and tap holes in a single step. Connect them directly to drills, power screwdrivers, and other tools that accept a 1/4" hex shank. They're made of high-speed steel and are for use on most metal and plastic. Their spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. Recommended for use in through holes, all have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.
Titanium nitride (TiN) coated taps last longer and can drill at higher speeds than uncoated taps.

Hex Shank Combination Drill Bits/Taps for Drills and Screwdrivers

Uncoated taps are strong enough for most tapping jobs but have the shortest tool life. Titanium Nitride (TiN) coated taps resist heat and wear better than uncoated taps, letting them last up to twice as long.

Impact Square Drive Size Adapters

Convert from one square drive size to another. The female side of the adapter attaches to your wrench; the male side to your socket. These adapters are made to withstand the high torque and force of impact tools.

Cobalt Steel Drill/Mill End Mills


Made of cobalt steel, these end mills have good heat and wear resistance, so they can run at high speeds in hard material. A 90° pointed tip allows them to be used for drilling as well as for slotting, profiling, and chamfering cuts. All are center cutting, allowing plunge cuts into a surface.
Use uncoated end mills for general purpose milling and short production runs. Use titanium-nitride (TiN) 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, which means they last longer when run at similar speeds.
