Unlock sharper drill bits with this diy drill bit sharpening jig

Sharpening drill bits is a crucial task for any DIY enthusiast or professional who relies on their drills for precise and efficient work. While purchasing commercial drill bit sharpening jigs can be expensive, building your own offers a cost-effective and customizable solution. This comprehensive guide will provide you with a step-by-step walkthrough on how to make a drill bit sharpening jig, empowering you to restore your drill bits to their optimal performance.

Materials and Tools Required

• Metalworking vise
• Angle grinder
• Drill press
• Drill bits (various sizes)
• Grinding wheel
• Measuring tape or ruler
• Pen or marker
• Safety glasses and gloves

Step-by-Step Instructions

1. Design and Sketch

Start by sketching the design of your jig on paper. Determine the size and shape that best suits your needs and the sizes of drill bits you intend to sharpen. Consider the angle at which the drill bits will be held against the grinding wheel.

2. Cut the Base Plate

Using the metalworking vise, secure a piece of metal stock and cut it to the desired size of your base plate. Ensure the plate is flat and sturdy to provide a stable foundation for the jig.

3. Create the Drill Bit Holder

Cut a section of metal stock to create the drill bit holder. Mark and drill holes to accommodate the various sizes of drill bits you plan to sharpen. Make sure the holes are aligned and accurately sized to provide a secure hold for the drill bits.

4. Attach the Holder to the Base Plate

Secure the drill bit holder to the base plate using screws or bolts. Position the holder so that the drill bits are perpendicular to the base plate and centered below the grinding wheel.

5. Build the Angle Guide

Cut a piece of metal stock to create the angle guide. Mark and grind an angle on the guide that corresponds to the desired sharpening angle for your drill bits. Secure the angle guide to the base plate using screws or bolts.

6. Install the Grinding Wheel

Mount the grinding wheel onto the drill press. Adjust the height of the grinding wheel so that it aligns with the center of the drill bit when it is held in the holder.

7. Test and Adjust

Insert a drill bit into the holder and secure it. Start the drill press and slowly lower the drill bit onto the grinding wheel. Observe the sharpening process and make any necessary adjustments to the angle guide or grinding wheel height to achieve the desired sharpening angle and result.

Advanced Features

1. Adjustable Angle Guide

Incorporate an adjustable angle guide that allows you to fine-tune the sharpening angle for different drill bit types and materials.

2. Coolant System

Add a coolant system to the jig to prevent overheating and extend the life of the grinding wheel.

3. Dust Collection

Attach a dust collection system to the jig to minimize dust accumulation and improve visibility during sharpening.

Tips for Sharpening

• Use a fine-grit grinding wheel for a sharper finish.
• Sharpen drill bits regularly to maintain their performance and prevent premature wear.
• Inspect the drill bits after sharpening to ensure they are sharp and free of burrs.
