Drill Bit Sharpener Buying Guide: What to Look For

Best Drill Bit Sharpeners Buyer's Guide

Following the considerations that experts believe are what make a drill bit sharpener great. As we’ve made efforts to make this your drill bit sharpener guide, you may make these considerations carefully to get help with the choice.

1. Size & Weight

A good drill sharpener handles drill bits of all varieties and is adjustable for the variable sizes. Also, it shouldn’t be too large or too heavy for your workspace.

2. Construction

The construction of the sharpener determines how you will feel working with it. To determine the level of flexibility and comfort you’ll derive, you should consider the material used for making the bits and the sharpener wheel.

Bits made of cobalt or high-speed steel and used to tackle plastic, wood, or soft steel can be sharpened with standard wheels of almost all varieties. Aim for getting a grit of 100 or higher as the higher grit runs more abrasively.

With brittle, carbide bits, your sharpener requires a diamond wheel. But don’t worry if yours doesn’t have it. You can always opt for an aftermarket upgrade. Regardless of the sharpener you have, you have to be careful when working on drill bits with titanium or similar coating.

3. Types

These devices come in two distinct styles, such as automatic and handheld models. Automatic sharpeners come with various settings for adjustment. As a result, you can sharpen the bits comfortably and accurately without having to use a firm grip and a steady hand. Handheld versions are the basic type that should be attached to a drill press for the operation.

4. Drill Bit Size & Material

Drill bits are made from cast iron, titanium, steel, and other strong alloys. If such a sharpener is made from a less solid material then it will not be able to cut or sharpen the bits effectively. Also, if the size is larger than the sharpener or much smaller then there will be difficulty working with it. Make sure that your tool can handle bits of most sizes and materials.

5. Compatibility

Your preferred model should be able to handle the operation with efficiency. If you are to use it with a drill press, its construction and design should match with the targeted drill. Also, it should be able to sharpen the bits efficiently irrespective of the size or material.

6. Speed & Accuracy

You should examine the different speeds and accuracy ratings to enjoy a sharpener that comes with a good speed and accuracy rating. There should be consistency in the speed and it should be able to withstand friction and heat. These machines are way faster than traditional paper drill bit sharpeners.

A sharpener that allows you to have more control of the speed and precision level is usually the most preferred. Although many prefer a two-step operation, a three-step process could also help achieve the desired results. Also, a wide-angle range will certainly result in more accurate and better quality sharpening.

7. Versatility

The higher number of sizes and types of drill bits that your device can handle; the better it can be compared to other choices. The goal is to pick something that helps you sharpen different types of drill bits with versatile functions and usability.

8. Ease of Use

To get your sharpener easy to operate, you may need to adjust its angle by inserting the bit and allowing the machine to take over. High-quality drill bit sharpeners will come with adjustability and modern control units. This is what you would want on most occasions. They are versatile and cover all sorts of bits, units, and brad points including those of an auger. You may use the instructions of a standard drill bit sharpener manual to ensure the perfect use of the machine.

9. Noise

Sure, you want to avoid annoying and unwanted noise that might leave you disgusted while getting the bits shiny and sharp. Those that produce some kind of sound but are not so noisy are what might attract your interest.

10. Grinding Stone

The quality of its grinding stone will determine its lifespan and you have learned (from the above discussion) a higher grit delivers the more abrasive power.

11. Warranty

The duration may vary depending on the manufacturer. However, as a rule, you should consider buying products with at least a one-year warranty. The longer the warranty period; the better it is for you.

12. Affordability

A top-quality device does not always have to be expensive. These tools are available at variable price ranges, starting from as little as $40 and running as high as a few thousand bucks. So, make a choice that fits all your expectations without exceeding your budget.

Why Use a Drill Bit Sharpener

Why Use a Drill Bit Sharpener

A drill bit sharpener is a tool or machine that you can use to renew your blunt or worn drill bits. It makes more sense if you can reshape your drill bits instead of throwing it away or buying a new one.

It is common for you to buy some drill bits of various sizes but end up only using a few of them. There’ll always be ones that will be left unused.

The frequently used sizes may become worn or blunt at some point, often a way faster than the ones used less frequently. Some persons will prefer buying another set of bits to getting them sharpened with a machine. However, some may still go asking if a drill bit sharpener works. Well, my answer is here.

Over the years of association with woodworking tools, we’ve learned that having a sharpener is an economical way to get the peak performance off the bits.

If you are like me who uses drill bits frequently, then you will find our review very useful in making the right buying choice.

Care & Maintenance

Knowing how to care and maintain your machine will not only prolong its lifespan but will ensure that you enjoy a fast and accurate operation anytime.

  • When you find that the machine is getting hotter, leave it for cooling. Wipe it with a piece of soft and moist cloth
  • When the sharpener is running, you should save your fingers from entering any of the machine’s openings
  • Once the device is on, don’t try to use your finger or any tool to make changes to its interior parts
  • If you experience any wobbling with the machine, all you need do is put a piece of soft cloth below the tool for a better balance
  • Make sure your machine has shield protection to keep it from harm and never try to sharpen a pencil or knife or anything else with it
  • Finally, your sharpener should have a capacity sack

A Word from Drillly

If you are a craftsman or a drill hobbyist, then you should be interested in getting a reliable and feature-rich drill bit sharpener. A blunt or worn drill bit will make your work slow, inaccurate, and discouraging. You can save money by purchasing such a tool to handle your old bits rather than buying a new set of bits. If you’d like to save more, you can try a homemade one with DIY techniques.

We feel it necessary to mention that our shortlist does not contain products from reputable manufacturers like Dewalt, Sierra Tool, PlasPlugs, Powerfix, VINtek, Makita, Bosch, Martek, Harbor Freight, or Dremel. This does not mean that those are of poor quality and the only reason they are not listed here is because they were not good enough to compete with these seven choices. Maybe we could pick some of those models if this drill bit sharpener review consisted of 20 or 30 picks instead of just seven.

There are many such products on the market, but it is our responsibility to provide you with options that can suit your preference based on the fundamental factors we have highlighted in this review. So, you should keep these factors in mind when shopping for drill bit sharpeners. Get Drill Doctor 500x if you want fast and accurate cutting while Tormek Sharpening System TBP805 can be your ultimate choice for your metal or wood store.
