3. Simple Steps to Sharpen Your Drill Bit Quickly and Easily
.
Step 1: Choose Your Sharpening Tool
The first step to sharpening a drill bit quickly and easily is to pick the right sharpening tool. You have two good options: an electric sharpening tool or a bench grinder. Both are good tools for sharpening, but the electric sharpening tool is usually faster and cleaner. Pick the one that best suits your needs.
Step 2: Secure the Bit
Before you begin sharpening, be sure to securely hold the bit in place. You want to make sure the bit isn’t slipping or moving around while you’re sharpening it. The best way to do this is to use a securely attached vise or clamp to hold the bit in place.
Step 3: Apply the Tool
Once the bit is properly secured in place, you can begin applying the sharpening tool. Start by lightly running the tool along the cutting edge of the bit for about 20–30 seconds. Make sure you’re applying pressure evenly to the entire cutting edge. Keep the tool steady and don’t apply too much pressure, as this can damage the bit.
Step 4: Repeat As Needed
After the initial sharpening is complete, check the bit for any burrs or imperfections. If there are any, repeat the sharpening process until the entire cutting edge is smooth and free of burrs or imperfections.
Step 5: Clean and Test the Bit
After the sharpening is complete, it’s time to clean and test the bit. Start by carefully cleaning the bit with a wire brush to remove any metal shavings or debris. Once the bit is clean, put it in an electric drill and test it out to make sure it’s sharp and up to the task.
4. Removing nicks from Your Drill Bit
When it comes to sharpening drill bits quickly and easily, understanding how to remove nicks plays a large role. There are several approaches you can take to remove nicks from the cutting edge of you your drill bits. Let’s look at the best methods.
- Sandpaper: Sandpaper is often used to remove nicks from drill bits because it can be used to get into tight spaces. Use an extra-fine grit sandpaper to achieve a smoother finish. Begin with 120 grit and gradually move up in grits until you have achieved a smooth cutting edge.
- Stone Grind: A stone grind is a sharper and faster method of removing nicks from the cutting edge of your drill bits. It’s important to use a stone bit that is specifically designed for sharpening drill bits. Always move the stone lightly and perpendicularly along the cutting edge to avoid damaging the tool.
Ultimately, the method you use to sharpen your drill bit will depend on two primary factors: your budget and the severity of the nick on your drill bit. If you have a deep nick, you may want to opt for a more expensive sharpening system over a simple stone or sandpaper. When in doubt, it’s best to consult a professional for advice.
5. Maintaining a Proper Angle while Sharpening
When sharpening a drill bit, it’s important to maintain the angle of the tip. An incorrect angle can throw off the effectiveness and accuracy of the drill. To help you sharpen your drill bit correctly and quickly, here is a guide to the angles.
Drill Bit Material
The angle you need to sharpen your drill bit varies depending on the material from which it is made.
- High-speed steel bits: 35 to 45 degrees
- Carbide bits: 45 to 55 degrees
- Cobalt bits: 45 to 60 degrees
To make sure you keep the proper angle, use a sharpening jig which makes it easy to make accurate and repeatable angles.
Drill Point Geometries
Drill bits come in a variety of point geometries, determined by the angle of the point.
| Drill Point Geometry | Angle |
|---|---|
| 118 Degree | 118 Degrees |
| 140 Degree | 140 Degrees |
| 151 Degree | 151 Degrees |
For special applications, drill points can have modified angles of 135, 134 or even 135.5 degrees. Select the point angle that suits the drilling application for maximum performance.
Using the proper angle when sharpening your drill bit will ensure that you get the most out of your drill bit and complete your project quickly and easily.
6. Finishing Steps for Sharpening Your Drill Bit
Now that you have worked through all of the above steps for sharpening a drill bit, you are almost done! In the last few steps, it is important to finish the sharpening process correctly to ensure that the bit is able to work as effectively as it should.
The following should be taken into the account when finishing the sharpening of a drill bit:
- Correct Angle: Ideally, your bit should be sharpened to a 120 degree angle. To measure the angle, use an angle gauge or angle finder.
- Consistent Edge: After sharpening the bit, it’s important that the edges on both sides of the bit are consistent. This is best achieved by testing how the bit cuts a piece of soft wood or aluminum.
- Smooth Finish: After sharpening and testing the bit, it’s important to finish the job with a smooth finish. This will reduce the risk of any of the sharp edges catching on the surface that you are drilling.
With these three steps, you should have a finely sharpened drill bit that is ready to tackle any job. Make sure to always keep it clean and store it in a dry place so that it lasts for as long as possible.
