An electric drill is a tool that is indispensable in any serious DIY individual’s toolbox. Not to be confused with a manual drill, an electric drill is an electrically powered instrument that uses different drill bits to create circular holes in various materials: wood, plastic, metal, concrete etc.

The drill bit is the part of the drill that succeeds in making holes in materials. These drill bits come in various sizes and shapes suitable for different tasks depending on the material. The bits are often made from high-speed steel (HSS) or carbon steel. Today, technology has availed us the opportunity to have even stronger and durable drill bits. Now, we see the use of cobalt steel alloys, and most remarkably, tungsten carbide.

Tungsten carbide has been around for a while, but its use in manufacturing drill bits has brought about a significant improvement in the performance and lifespan of these tools. This hardness and resistance to heat make tungsten carbide the material of choice for drilling applications that require a high level of precision and durability.

One of the best ways to get high-quality drill bits is during a tungsten carbide blanks sale.

This is a sale event where raw materials (blanks) for manufacturing heavy-duty drill bits are sold at discounted prices, attracting many manufacturers and DIY enthusiasts.

How Electric Drills Work?

To understand how an electric drill operates, the key parts you should know about are the trigger, motor, clutch, and the gearbox. Pressing the trigger initiates a flow of electric current, which powers the motor. The motor spins a set of gears that are attached to the chuck. The chuck then rotates the drill bit, which does the actual task of drilling into the material.

Types of Electric Drills

There are three main types of electric drills: Handheld drills, hammer drills, and rotary hammers.

Handheld drills: These are the most common type of electric drills. They are lightweight, portable, versatile, and suitable for a myriad of household and professional tasks. Handheld drills can easily drill into wood, aluminum, plastics, and even mild steel.

Hammer drills: This type of drill is more robust and is used to drill into concrete and masonry. In addition to rotation, hammer drills use a rapid hammering action to pulverize material and drive the bit deeper.

Rotary hammers: Rotary hammers offer the most power among all electric drills. They use a piston mechanism instead of a special clutch, enabling them to deliver a much more potent hammer blow, making them ideal for heavy-duty jobs like drilling into solid concrete or breaking up pavement.

Tips for Using Electric Drills Safely

Though electric drills are handy, they are also potential hazards. Here are a few tips for using electric drills safely: Always use the correct drill bit for the material, give your drill time to cool down after extended use, never use a drill with a damaged cord, and always wear safety gear.

In conclusion, electric drills have evolved from simple tools to powerful, complex devices that are indispensable in various industries. Their versatility and power make them one of the most widely-used power tools today. However, their effectiveness heavily relies on the drill bits’ quality – a reason why the event such as a “tungsten carbide blanks sale” matters.
