Why I Always Keep an Extra Long 4 mm Bit in My Toolbox

Additionally, a 4 mm bit size is versatile and commonly used in various applications such as electronics, small appliances, and even some furniture pieces. By having an extra long 4 mm bit on hand, I don’t have to worry about constantly switching between different size bits for different projects.

Furthermore, the quality of the bit is important when it comes to durability and effectiveness. With an extra long 4 mm bit made from high-quality materials such as hardened steel, I can trust that it will not break or wear out easily.

My Buying Guide on ‘Extra Long 4 Mm Bit’

As a handyman, I have come across many different types of drill bits in my line of work. From short bits to extra-long ones, each serves a specific purpose. However, when it comes to drilling through thicker materials or reaching tight spaces, an extra-long 4 mm bit is an essential tool in my toolkit. In this buying guide, I will share my experience and tips on choosing the best extra-long 4 mm bit for your needs.

What is an Extra-Long 4 Mm Bit?

An extra-long 4 mm bit is a type of drill bit that has a length longer than the standard size. It is designed specifically for drilling through thick materials or reaching deep and narrow spaces. This type of bit usually has a length of 6 inches or more, making it ideal for various tasks such as plumbing, electrical work, and carpentry.

Things to Consider Before Buying an Extra-Long 4 Mm Bit

Before purchasing an extra-long 4 mm bit, there are some essential factors that you should consider to ensure you get the most suitable one for your needs.

1. Material

The first thing you need to consider is the material used to make the drill bit. Typically, extra-long 4 mm bits are made from high-speed steel (HSS), cobalt steel, or carbide. HSS bits are suitable for general drilling tasks and have a lower price point, while cobalt steel and carbide bits are more durable and can withstand higher temperatures and keep their sharpness for longer.

2. Shank Size

The shank size of the drill bit is another important factor to consider. The shank refers to the part of the bit that attaches to the drill’s chuck. Make sure that the shank size matches your drill’s chuck size; otherwise, it will not be compatible.

3. Length

Extra-long 4 mm bits come in various lengths ranging from 6 inches to over 12 inches. Consider the task you will be using it for and choose a length that will allow you to reach deep or narrow spaces comfortably.

Tips for Using Extra-Long 4 Mm Bits

Once you have purchased your extra-long 4 mm bit, here are some tips on how to use it effectively:

  • Always wear protective gear such as safety glasses before using any power tools.
  • Use cutting oil or lubricant when drilling through metal materials.
  • Start with low speed and gradually increase while drilling.
  • Avoid applying excessive pressure as it can damage both the bit and material.
  • If possible, use a drill press instead of a handheld drill for better control.
  • Clean off any debris from the drill bit after each use to prolong its lifespan.

In Conclusion

An extra-long 4 mm bit is a valuable addition to any handyman’s toolkit. With its ability to reach tight spaces and drill through thick materials effortlessly, it can save you time and effort in completing various tasks. By considering factors such as material, shank size, and length before purchasing one and following proper usage tips, you can ensure that your extra-long 4 mm bit serves you well for years to come.
