Some drills, 20V MAX* Lithium-Ion Drill/Driver, feature a built-in LED to illuminate your work surface. This can be a lifesaver when you’re drilling or driving in tight or dark spaces like inside a closet or under the sink.

BLACK+DECKER® drills and all-in-one drill/drivers simplify hundreds of household projects, from installing shelves to hanging blinds and assembling furniture – all the things that help make a house a home.

Drill/Drivers feature a manual or automatic clutch mechanism to adjust the drill/driver’s torque (turning power). Drill/Drivers with automatic clutches, like this 20V MAX* Lithium-Ion Drill/Driver with AutoSense™ Technology, are great for beginners because they take the trial-and-error out of getting just the right amount of torque. Torque control is what separates a drill/driver from an ordinary drill. Most manual clutch drill/drivers have a numbered dial that makes torque adjustment easy. Use less torque (a lower number) for softer materials like drywall or when you want to limit how deep the screw goes. Use more torque for hard woods or when you want the screw flush or countersunk.  When you’re not driving, simply set the clutch dial on drill mode.

The chuck is a three-point clamp that holds the bit securely in place. Some drills come with a small key to tighten the chuck, while keyless chucks are tightened by hand. A clockwise turn tightens the chuck; a counter-clockwise turn releases the bit. Chucks come in dual-sleeve and single-sleeve configurations, with single-sleeve offering easy one-handed operation.

Cordless drills are convenient, compact, and easy to maneuver, so they can be used anywhere.  You’ll appreciate cordless flexibility when you’re out in the yard repairing a gate or up on a ladder installing a light fixture. A lithium-powered cordless drill such as our 20V MAX* Lithium-Ion Drill/Driver will give you plenty of runtime for basic projects.

Jobber bitvs drillbit

All power drills have a forward (clockwise) and reverse (counter-clockwise) switch, usually right above the trigger. After drilling, setting the bit direction to reverse spins it counterclockwise to help it come out of the hole cleanly and easily. You’ll also use reverse mode to quickly remove screws and other fasteners.

Simply, drilling is making a hole, and driving is securing a screw or other fastener. Drill/Drivers do both jobs, which is convenient for projects like hanging a mirror, where you might drill a pilot hole then drive in a screw.

Today Jobber Drill Bit are manufactured in a number of different style to tackle a number of different applications. Jobber Drill Bits still remain the most commonly found type of drill bit. A jobber drill bit has a long length compared to its diameter. The length of the flute is between 8-12 or 9-14 times the diameter of the drill, depending on the drill specifications. For example, a 1/2″ diameter jobber drill will be able to drill a 4-1/2″ deep hole because it is 9 times the diameter in length. Jobber drills are measured using a number of different systems:

Corded drills require a power source and tether you to a cord, but they offer the benefit of unlimited runtime and increased power for large or complex projects you want to finish without recharging a battery. You can’t go wrong with a corded drill like this BLACK+DECKER™ 20V MAX* Lithium-Ion Drill/Driver.

The general definition of the term “jobber” is “a person or company that buys from manufacturers and sells to retailers”, most commonly used in the 1850-1950 period. At that time, manufacturers were mostly producing general purpose “for the trade” drill bits, not using specialized machining applications to make specific lengths or designs like today. These drills, were of medium length and suitable for a wide variety of jobs, coining the term “jobber-length”, reflecting the same concept of terms like “general purpose” and “multipurpose”. Today, jobber drill refers to the length of the drill itself.

Most drill/drivers have a trigger to control how fast the drill spins, so for basic projects, a one-speed drill is all you need. If you need more precise speed control for diverse drilling or driving projects, a multi-speed drill like the BLACK+DECKER 20V MAX* Lithium-Ion 2-Speed Drill/Driver is worth a look. Use high speed for small, fast holes and driving and a low speed for high-torque applications like drilling large holes.
