Drill Bit Sharpener Features and Considerations

It’s essential to look at the type of bits you intend to sharpen when looking for a sharpener. As such, it will be a good idea to pick one that can sharpen different types of bits, especially split points, and masonry bits since they are the most difficult drill bits to sharpen. Here is what you need to consider while shopping for the best drill bit sharpener:

Type of Sharpener 

There are many types of drill bit sharpeners available. However, you can distinguish them by checking their size and shape since some are small while others bulky and large. The most common type of sharpeners includes:

Portable Sharpeners

These drill bit sharpeners are small and ideal if you intend to work with your drill in remote areas. In case your drill bits get damaged or dull, you can sharpen the bits quickly on the project site. One major issue with portable sharpeners is that their sharpening power is slightly lower than that of a tabletop sharpener. Due to this, you cannot use them for harder and large drill bits. In addition, they are not as stable as their tabletop counterparts and are expensive.

Tabletop Sharpeners

Unlike portable sharpeners, tabletop sharpeners are affordable, stable, and reliable. However, they are not suitable for people with limited spaces as they tend to occupy a lot of storage space in the workshop. You may also need to look for another alternative if you plan to carry them to different project sites to sharpen drill bits as they are heavy. 

Drill Bit Angle

Drill bits have a unique tip angle used for drilling. The tip can be difficult to sharpen if it’s not making the right contact with the drill bit sharpener. You can also damage your drill bits if the sharpening angle is incorrect. This happens when you use your sharpener to sharpen the drill bit at a sloppy angle. 

To prevent this from happening, find the point angle that is compatible with your drill bit sharpener. Fortunately, many drill bits provide a range of this angle, which you can easily adjust. This means you can adjust the angle depending on the drill bit you want to sharpen using the drill bit sharpener.

Drill Bit Size

Before buying your drill bit sharpener, you should ensure your drill bits fit perfectly in the sharpener. This is an important factor to check since there are various types of drill bits that have different diameters and lengths. Most drill bit sharpeners come with a diameter rating that indicates the maximum thickness they can accommodate.

The rating is given in inches and ranges from 3/8 inches to ½ inches. For this reason, you need to ensure that the diameter of your drill bits is compatible with the diameter rating on the drill bit sharpener you want to buy.

Type of Drill Bit

Apart from the point angle and size of your drill bit, you should also consider the type of drill bit you are using since different types of drill bits work differently. This means your drill bit sharpener is only compatible with certain types of drill bits.

If your sharpener and drill bit are compatible, you will not experience any challenges while sharpening. You can damage either the drill bit sharpener or the drill bit and, in some cases, both if there are compatibility issues.

The material used to make the drill bit is also worth considering. For instance, carbide is a tough material and much difficult to sharpen using a drill sharpener. Likewise, drill bits built with weaker alloys such as carbon steel make sharpening a breeze. You can sharpen such drill bits using a portable sharpener without any problems.

Durability

Over time, a drill sharpener can become dull which can make sharpening more drill bits difficult. Apart from making it blunt, you can also end up damaging the drill bit sharpener. So, you have to invest in a durable sharpener that will give you reliable service. 

You should consider sharpeners built with high-density metals such as silicon carbide and cast aluminum as they are durable and sturdy. You should also check the overall construction since some power tools vibrate, which can make them fall apart if constructed poorly.

Accuracy and Speed

Before making the purchase, check the accuracy and speed ratings on your product. A sharpener with good ratings will withstand heat and friction and also deliver consistent speed. Additionally, you should also consider sharpeners that enable you to have more control of the precision level and speed. You should also choose products with a wide-angle range as they result in better quality and accurate sharpening 

Wrap Up

If you have dull drill bits at your woodshop or home, use a good drill bit sharpener to restore the bit’s sharpness and improve its performance instead of replacing or throwing them away. The sharpeners we have reviewed above are versatile and can handle a variety of bits. 

They are also easy to maintain, deliver excellent results, and produce minimal noise. Don’t allow a blunt drill bit to ruin your projects. Pick any sharpener from our list and restore the sharp edges of your drill bit.
