![]() This will absorb most of the vibrational energy. To ensure this, you would typically attach your grinder to your working bench. The most important thing here is that the wheel should move and operate very smoothly without any visible vibrations. What I typically recommend is that before you go ahead and start your grinding wheel, make sure that all the equipment that you need is available and at hand. Planning is essential when performing a drill sharpening job. This step is often overlooked by even the professional tool operators. If you are in a rush, no worry, I have got you - watch this simple video below. Angled jig (buy it or get it custom made)Ħ Steps guide on how to sharpen drill bits.To perform this task you do not require to much in terms of equipment. Equipment You’ll Need To Know How To Sharpen Drill Bits It is generally recommended to also use ear protection as this will reduce the likelihood of any damage that can be caused from the high pitched noise as you sharpen. I would go as far as to say that you should never deal with such equipment without the use of protective workman gloves and eye protection for small metal splinters. ![]() Whenever you are working with high speed steel or rotating mechanical parts such as drill bits, you should always equip yourself with personal protective equipment. Your drill bit would just overheat unnecessarily. Without this angle it would be like you are trying to drill with a flat face. The tilt angle basically helps funnel the material and debris through your flutes. If you can get approximate values you generally will be alright. One thing I want to point out is that sharpening a drill bit is definitely not an exact science.

The second critical item is your cutting edges should be identical. Plus - Reducing it’s overall life and making it harder to maintain stability. If the sides are not symmetrical this puts further mechanical stress on your drill bit. The reason for this is because the drill will be rotating around the chisel point (tip). You must ensure that as you are sharpening your drill which shall be explained below, you maintain symmetry on both sides. See the image below and lets discuss these. ![]() No matter which method you use either a drill kit or using a grinding wheel without any support there are primarily 3 things you must get right to ensure a solid drill finish. 3 key things you must get right to sharpen you drill bit correctly In my opinion, these drill bit kits are not really required, especially if you have a grinding wheel slot that can maintain the an angle with some flexibility to allow you to rotate the drill bit a little for smooth sharpen. It’s a mechanical looking contraption that is designed to hold your drill bit at a specific angle to ensure that you can have nice and smoothly sharpened bits. If you go to any hardware store or convenience store that sells drill bits, you will usually also find a section that sells some form of drill sharpening kit. Drill bit sharpening kits (what is all the fuss) Now that you know this to get your drill bit back into tip top shape all you really need to do is restore the drill bits tip back to the original 118°. Therefore when your drill bit (which is typically high speed steel) loses it’s ability to drill effectively and thus becomes dull, it is because technically the angle has become reduced. Many years of research have provided that the 118° angle is optimal. The flat edge material would just heat up quite a bit and not get very far into the metal or wood. ![]() Infact, I can tell you what would happen. The reason for this is simple the surface area for the torque is far to large and dispersed to create any sort of penetration through the material. Let’s take a look at an extreme case, image you tried to drill into a piece of stock material with a flat edge, you would not get very far no matter how much speed you rotated it. But you might be thinking what is a dull drill bit anyways? However, as you already know when drilling into steel or metal the high speed steel will still go dull. ![]()
