Performance similar to solid carbide but at a lower price point. Like carbide bits, these are stronger than cobalt and high-speed steel and maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like iron and hardened steel, upgrade to carbide for longer life.

Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.

When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Also known as indexable drill bits.

Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

These rods, also known as drill blanks, have an undersized diameter for machining your own drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

A traditional pistol-grip shape makes these drills suitable for a variety of drilling applications. They have a variable speed motor—the further you depress the trigger, the faster the drill rotates.

Safely test for live circuits before driving screws and nuts. A detector snaps in and out of the handle of these screwdriver/nutdrivers to check for voltage without touching live wires. Light and sound indicators alert you when over 50 volts AC is detected. These tools come with reversible bits and shafts to turn multiple fastener sizes. Insert a bit into the shaft to drive screws or use the shaft on its own to turn nuts. All nest together to store in the body of the tool. Also known as 10-in-1 drivers.
