In addition, a brushless motor or a variable speed trigger, which offers greater control, increases its durability.

Material & Durability of drill with variable speed

The durability of a variable speed hammer drill depends on the materials used in its construction. Buyers should prioritize durable drills, as they will appeal to customers who seek long-lasting tools. Here are the different materials that make drills:

• Gearbox

  The gear speed box is one of the most important parts of a cordless drill. It controls the torque by regulating the speed of the motor's gears, thus multiplying the motor's torque by the geared ratio. Most gearboxes are made of metal alloys or steel, which are more durable than plastic, especially under heavy use. A good-quality gearbox will provide many years of effective operation, even in the most demanding situations.

• Chuck

  The chuck, or the part that holds the drill bit or other attachments in place, can be key or keyless. Chucks are made of various metals, such as steel or hardened carbide, for strength and durability. For instance, steel chucks are very strong and give a good finish. In contrast, carbide chucks are much harder, giving more wear resistance and, therefore, a longer life to the chuck.

• Housing

  The outer casing or housing of a drill protects all the internal working parts. This casing can be made of various materials, such as plastic, metal, or composites. These materials include ABS plastic, polycarbonate, or high-strength thermoplastics. They are all strong enough to protect the internal motor, gears, and electronics from damage. Other than that, these materials are water-resistant, providing additional protection against water and moisture damage.

• The Armature

  It is found in a wired drill and plays an important role in the operation of the motor. Armature rods are made of copper wire insulated for electric windings. This creates a strong magnetic field when the motor spins, enabling the drill to drive bits. An electric drill with great torque will have a well-constructed armature to improve performance.

• Bearing

  Bearings reduce friction between moving parts for smooth operation. Ball bearings are commonly used due to their durability. They are often made from chrome steel, ceramic, or stainless steel for long life. They are located near the pinion gear, chuck, and rotor of the motor for greater accuracy.

Commercial use cases of drill with variable speed

A variable speed cordless drill is used in many business sectors. It will help to know how each sector uses the drill and what their needs are. The following drills also suit the below industry applications:

• Construction industry

  Electrical and general contractors, as well as electrical installers, need drills for heavy work fast. Hammer drills will, therefore, be appropriate for their concrete or masonry drilling needs. Moreover, impact drills or drivers will suit those who wish to drive screws in wood. Other than that, these drills are made to last even with tough daily use.

• Mechanical workshops

  People doing auto mechanic mobile work and car service use drills to do auto repairs and maintenance. Cordless drills give them power and mobility as they drill, drive screws, or do detailing on their vehicles. They also appreciate drill combs or multi-tool drills, which are versatile and can be used for many tasks.

• Manufacturing industry

  Drills are used in assembling, fabricating, and creating products in factories, workshops, and plants. In fastener driving applications, industrial drill drivers and screw guns are used. On drilling applications, corded and cordless hammer drills are used. Special drills for industrial use are designed for accuracy and to work hard for many years.

• Remodelling and repair businesses

  Contractors and DIYers doing home remodelling or repairs also need drills. Cordless or corded drills can suit general home use, such as drilling or driving screws. More intensive home projects, such as basement or attic conversions, may need drills with special features.

• Other industries

  Apart from the above, other industries that require variable speed drills include furniture manufacturers, cabinetmakers, and millworkers. They will all need drills suitable for drilling, driving, and other specialised tools. Variable speed drills are favored here for their versatility in handling different drilling and driving tasks efficiently.

How To Choose drill with variable speed

When choosing drills, one can refer to the following points and stock variable-speed drills that suit the customers' needs:

• Speed and power

  The main difference between the two drills is the number of speed settings. Simple drills have one or two-speed settings. In contrast, complex drills have ten or more speeds for various applications. High-speed models are good for boring. High torque models are good for screw driving.

• Chuck size

  The chuck size determines the bit sizes the drill can accept. If a drill has a larger chuck, it will accept larger bits, allowing it to do more tasks. Most cordless electric drills have a chuck of 0.5 inches, which can accommodate most bits. However, some have a chuck of 0.25 inches for lighter work. A hammer drill will have a larger chuck than an impact driver.

• Power tools vs. hand tools

  Corded and cordless drills are both power tools, but drills can also be found, which are hand-driven. Cordless drills are more convenient, while corded drills are more powerful. Moreover, corded drills are less expensive than hand drills. Drill presses and drills with variable speed for metals are introduced for specific uses.

• Torque

  Torque is rotational force measured in units called inch-pounds or Nm. Generally, the higher the torque, the greater the drill's capability to drive larger screws or drill through denser media. Variable speed drills have adjustable torque settings for better control.

• Battery type

  Lithium-ion batteries are preferred for speed drills. They hold a charge longer and can be recharged in a short period. Other battery types include nickel-cadmium and nickel-metal hydride. However, these take a longer time to charge, and a charge will not last as long as Li-ion.

• Price

  Variable-speed drills are priced rather differently because of their wide range of specifications. Generally, simple drills are less expensive than the advanced types. Corded drills cost less than cordless drills due to their simplicity. Broadly, professional-grade drills are pricier than consumer-grade drills.

Q & A
