The Necessity of Long Drill Bits for Metal

As a DIY enthusiast and frequent user of power tools, I have come to learn the importance of having the right tools for the job. When it comes to drilling through metal, using long drill bits is absolutely necessary.

First and foremost, metal is a tough and durable material that requires a strong and precise force to penetrate. Standard drill bits are usually too short to effectively drill through thick metal sheets or pipes. This can result in uneven holes or even breakage of the drill bit. Long drill bits, on the other hand, provide the necessary length to reach deep into the material without compromising stability.

Furthermore, long drill bits also allow for better control and accuracy when drilling through metal. The longer length provides a larger surface area for gripping and maneuvering, making it easier to maintain a steady hand while drilling. This is especially important when working with delicate or intricate metal pieces where one wrong move can ruin the entire project.

In addition, using long drill bits can also save time and effort. Since they can reach deeper into the material, there is no need to constantly reposition or adjust the workpiece. This results in a smoother and more efficient drilling process.

My Buying Guide on ‘Long Drill Bits For Metal’

As someone who has worked with metal for years, I understand the importance of having the right tools for the job. When it comes to drilling through metal, using a long drill bit can make a world of difference. From drilling through thick sheets of metal to creating precise holes in tight spaces, long drill bits are essential for any metalworker’s toolkit. With that in mind, here is my buying guide for long drill bits for metal.

1. Consider the Material

The first thing to consider when buying a long drill bit for metal is the material it is made of. High-speed steel (HSS) is a popular choice as it is durable and can handle high temperatures without losing its hardness. For heavier-duty tasks, cobalt steel or titanium-coated bits may be a better option as they are even more heat-resistant and can cut through tougher materials like stainless steel.

2. Know the Size

Long drill bits come in various sizes, and it’s essential to know what size you need before making a purchase. The standard measurement for drill bits is in inches, with diameters ranging from 1/16 inch to 1 inch or larger. Make sure to measure the thickness of the material you will be drilling through to determine the appropriate size.

3. Check the Shank Size

The shank size refers to the diameter of the part of the drill bit that fits into your drill’s chuck. Long drill bits typically have a shank size of 1/4 inch or 3/8 inch. It’s important to check this measurement as not all drills can accommodate both sizes.

4. Look at the Flute Design

The flute design refers to the spiral grooves on the body of the drill bit. They help to remove debris and keep the drill bit cool while in use. For drilling through metal, a helix-shaped flute design is ideal as it creates less friction and allows for faster chip removal.

5. Consider the Point Angle

The point angle of a drill bit determines the type of material it is best suited for. For drilling through metal, a point angle between 118 and 135 degrees is recommended. A sharper point angle will provide better precision and control while drilling.

6. Check for Coating

Some long drill bits come with a coating, such as black oxide or titanium, to increase their durability and reduce friction while drilling. This can be beneficial when working with tougher materials or for prolonged use.

7. Read Reviews and Compare Prices

Before making any purchase, it’s always a good idea to read online reviews from other buyers to get an idea of the product’s quality and performance. Additionally, comparing prices from different retailers can help you get the best deal on your long drill bit for metal.

In conclusion, investing in a good quality long drill bit for metal can save you time and frustration in your metalworking projects. By considering the material, size, shank size, flute design, point angle, coating, and reading reviews before buying, you can ensure that you choose the right long drill bit that will meet your needs and last for years to come.
