Best Drill Sharpeners in 2021


Drilling machine efficiency is a major determinant of the quality of drilling work completed. Sharp drill bits increase this efficiency, and for this reason, it’s critical to have the right drill sharpener. Just like other machine parts need regular maintenance, drill bits require regular sharpening.

How do you know that it is time to sharpen your drill bit?

If the drill bit produces inaccurate results (for example, splintering in wood), or working slower, it’s time to use a drill sharpener. Besides, through visual inspection, you can determine if the drill bit has gotten chipped over time.

When choosing a drill bit sharpener, precision, and safety drill bit sharpening is your main focus. It goes without saying that using the wrong sharpening tool can produce unevenly sharpened drill bits. More importantly, you can injure yourself seriously when not using the right tool.

Consideration to make when choosing the best drill sharpener

  • Drill bit sizes, point angles, and material the sharpener handle: This is an essential consideration, and that’s why it comes first. You need a sharpener that can accommodate the drill bits you use the most.
    Drill bits have either a 118-degree or 135-degree point angle. The drill bit sharpener you choose should work with the drill bit’s angle.
    Likewise, ensure that the sharpener can handle the bit material. Some bits are made from titanium or cobalt while others are made from high-speed steel (HSS). The harder the drill bit material, the more difficult it is to sharpen.
  • Sharpener accuracy: The shape of the tip dictates the angle to which the drill bit has to be sharpened. An accurate drill sharpener is precise in shaping bit edges, which results in accurate drilling results.
  • Flexibility: Some sharpeners are designed to sharpen not only drill bits of different sizes and shapes but also other workshop tools including scissors and knives. They may cost more compared to one-function sharpeners, but you derive more value from them in the long-run.
