Criteria for Evaluation
When choosing the options in our top 10, we made sure to follow some strict quality criteria. We suggest you use the same criteria for your own search before making a purchase.
Drill bits come in several metal variations, and their suitability for working with particular materials also differ significantly. In case you are intending to use the drill bits to bore through metal, pay particular attention to available robust varieties capable of delivering superior performance. Abrasive materials such as aluminium and stainless steel, for instance, will necessitate the use of industrial-strength drill bits that do not whether quickly.
Design of Drill Bits
Having decided on your preferred construction material, the subsequent step is looking at the most suitably designed drill bits. Other than differences in design, there are also differences in boring angles, and your choice should be informed by the materials you intend to drill. A step-design is more appropriate for drilling through hard metals compared to twist designs.
Drilling is a tough job, and in cases involving hardened metals, there is a high likelihood of generating high temperatures and corroding the cutting edge of the drill bits. As a result, it is important that your choice takes these two factors into consideration when searching for drill bits. Time and again, titanium and cobalt have been praised highly for their ability to resist heat and abrasion.
As already mentioned, drilling through hardened materials generates heat and friction, which, with increased use, reduces the cutting edge of the drill bits. Since titanium is an industrial-strength material, sharpening it is exceedingly difficult. Cobalt, on the other hand, is easy to re-sharpen. Since titanium coating guarantees you a longer shelf-life, sharpening it may negate this advantage.
Type of Coating
Drill bits have sharp tips that various manufacturers make a point of coating so as to enhance their versatility and performance. The two most common types of coats used are the black oxide and titanium oxide or nitride. While the former is effective at strengthening the tips, it is unsuitable for non-ferrous metals. The latter, on the other hand, increases the capability of drill bits to bore through abrasive materials by increasing their resistance to corrosion and strength.
Q: What are drill bits?
A: Drill bits are the apparatus professional contractors, and DIYers use to bore holes through the surface of different materials such as wood, PVC pipes, metals, and plastics. They vary greatly in design and size. While those with twist designs are more suited to drill through metals, plastic, and wood, the ones with step design easily drill through abrasive materials.
Q: What types of materials are used to make the drill bits?
A: Drill bits are made from numerous materials offering different degrees of resistance to wear-and-tear, strength, and cutting edge. The harder the material used to make a drill bit, the more expensive it will be. The various types of materials used to make drill bits, in ascending order of hardness, are carbon steel, high-speed steel, cobalt steel, titanium-coated, and lastly carbide. The main difference between titanium-coated drill bits and carbide drill bits is that the latter drills through stainless metal and other hardened materials with a lot of ease.
Q: How do I stay safe while drilling?
A: When paired with hammer drills, drill bits rotate at exceedingly high speeds and in the process of drilling, especially through metal, produce a lot of drilling debris that could get into your eyes. Given the proximity of your face to the flying shards and splinters, it is a good to protect your eyes by wearing eye protecting goggles. Heavy-duty projects will automatically necessitate the use of gloves and ear buds in addition to the goggles. As much as possible, have an extra pair of hands in the workstation to help with handling heavier drilling materials. C-clamps are of great help with securing smaller applications together before drilling.
Drill bits today are considered a necessity in the workstations of professional contractors and at home. They are a must-have tool for those who regularly perform repairs and improvements around the house. We based our selection of the ten best drill bits on the material used to make drill bits, design, longevity, the possibility of re-sharpen, and the type of coating.
