Handheld power drills are accurate tools, but most woodworkers avoid them, and instead they opt for a drill press. Not every woodworker will have adequate room for the bench top drill press or the full scale standing model.
For most handheld power drill, power is measured according to the battery voltage. Those with higher battery voltage have more torque spinning strength necessary in overcoming resistance.
Within the last one decade, the top end voltage has gradually increased from 9.6 volts to 18 volts, but most models in the market include, 6, 7.2, 14.4 volts and 18 volts. The high voltage drills have more power and can bore bigger holes in flooring and framing lumber.
That sounds good, but one tradeoff power is the weight. Typical 9.6v handheld drills weigh around 3.3 pounds while the 18-volt models weigh around 10 lbs.
The handheld power drills handles
Some years ago, most handheld drills had pistol handles and the handle more like that of a gun. However, today, most drills have T-handles. The handle base of such a drill flares to prevent the users hand from slippage and also accommodate the battery.
The battery of a drill with a T-handle is usually situated under the motor and the weight of the drill. Therefore, the T-drills offer more balance, particularly in the heavier high voltage drills.
A pistol drill, on the other hand, allows you to apply more pressure directly to the bit and as a result, you employ more force on your work.
Adjustable grips are what separates electric drills from the cordless drills. Clutches are usually placed in the chuck and disengages the drill’s drive shaft and makes a clicking sound whenever a preset resistance level is attained.
As a result, the motor can continue turning while the screwdriver bit isn’t. The clutch enables the user to control the drill – so that they cannot override or strip a screw.
The clutch also helps in protecting the motor whenever lots of resistance is reached. Clutch settings highly vary from one drill to the other, and most drills have only 24 settings.
With such number of settings, the user can fine tune the power which the drill delivers. The larger numbers are for, the larger screws.
Most drills on the market run either on a single speed or two fixed speeds. These speeds are 300 rpm and 800rpm.
Slide switches or triggers allow the users to select the low or high speed. The handheld power drills are ideal for the light duty operations.
The higher speed is necessary when drilling holes and the lower speed when driving screws.
For the more refined repair and carpentry tasks, you should choose the drills that have one-speed switch and a trigger with the variable speed control which allows you to vary the rate from 0rpm to the highest range.
