Also known as gun taps, the taps in these sets have spiral-point flutes that push chips ahead of the tap and out of through holes. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. Taps have a square shank for compatibility with tap wrenches and tap holders for drill presses and milling machines. With a plug chamfer, they have 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. All taps and drill bits are made of high-speed steel for use on most metal and plastic.

Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.

The hardest and most wear-resistant bits, the flutes clear chips and improve coolant flow. They prevent clogs and dissipate heat that can damage the bit and the hole. Carbide bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.

Drill safely in flammable environments. Made of beryllium copper, these bits won’t create sparks that could ignite upon contact with combustible vapors or residues. They're Factory Mutual (FM) approved and help you meet OSHA requirements in areas 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.
