It is an important tool for locksmiths. Let’s learn a basic thing about it today.
Electric drill is an electrical motor that rotates a replaceable drill bit to make a hole in metal, wood or plastic. Alternately, a screwdriver tip can be installed to turn screws.
The parts of a power drill include the handle, an on/off trigger with safety latch, and a reversing switch for changing the rotation direction of the drill bit, a torque adjustment, and the chuck that holds the drill bit in place
For locksmiths, it is used as a locksmith tools for installing locks, drilling into locks and safe, installing various exit devices, etc. A high quality drill can cost several times more than a low quality drill, but it is typically worth the extra money. It will provide many years of heavy-duty service and save you time and energy.
Most common basic drill sizes that are available: 1/4 inch, 3/4 inch and 1/2 inch. A drill’s size is based on the largest diameter drill bit shank the drill’s chuck can accept without adapter. Example, a drill whose chuck can hold a drill bit shank up to 1/2 inch in diameter is a 1/2 inch drill.
A drill’s power is a combination of chuck speed and torque. Check speed is measured in revolution per minute (when spinning freely in the air). Meanwhile torque refers to the twisting force at the chuck when the drill is being used to drill a hole.
The type of reduction gears on a drill largely determines chuck speed and torque. Reduction gears work like a car gears. A drill with a single stage reduction gear set has a chuck that spin very fast in the air (high rpm) but slows down considerably when drilling a hole.
Meanwhile a drill with a three stage reduction gear set has fewer rpm but more torque. Therefore if we used a drill with a higher reduction gear set, the drill become slower but more powerful.
Most 1/4 inch drills have single stage reduction gears set, which can allow a chuck to spin at +- 3000 rpm. Do not use it to drill hardwood or steel because it could damage the drill and consume a lot of time.
A 3/4 inch drill is usually faster than 1/2 inch drill and provides more torque. Usually it spins at about 1500 rpm. Very useful for drilling metals up to 3/4 inch thick and wood up to 3/4 inch thick.
A 1/2 inch drill usually has a two stage or three-stage reduction gear and it’s chuck can spins at about 650 rpm. This drill is the most popular among locksmiths because it’s wide jaws allow it to hold auger bits, boring bits and a variety of shanks. This type of drill is most useful for installing locks and door hardware or for drilling open safes.

When looking for a high quality drill, important features to look for include two or three stage reduction gear sets, minimum speed 650 rpm, variable speed reversible control switch, double insulation, all anti-friction (needle or ball) bearings and minimum power required is +-5 amps.
Variable speed drill is the best because it’s allows you to use any speed from 0 rpm to the drill’s highest speed and for the power (measured in amps), the more amps a drill uses, the more powerful it is.
Steps To Safely Use Your Locksmith Tools (Electric Drill)
1. Make sure the drill switch is in the off position and/or unplug the electrical cord if so equipped.
2. Loosen the chuck and insert the appropriate bit or tip shaft, then tighten the chuck. Some power drills require a special tool to firmly tighten the chuck.
3. Set the torque adjuster to control slippage of the drill bit, useful when turning screws without damaging the screw head.
4. Plug in or insert the battery into the power drill.
5. Place the point of the drill bit or screwdriver tip as needed.
6. Press the safety latch and on/off trigger.
7. Push the drill bit or screwdriver forward as the chuck rotates.
Maintain Your Locksmith Tools (Electric Drill)
Even though electric drills require little maintenance but it can be damaged by improper use, such as using the wrong drill bit or tip, which can drag down and damage the motor.
