Drill bit sharpening jig: the ultimate guide to razor-sharp bits

Sharpening drill bits is a crucial aspect of maintaining their performance and extending their lifespan. A well-sharpened drill bit ensures precise drilling, prevents material damage, and enhances overall productivity. While manual sharpening techniques exist, using a drill bit sharpening jig offers greater accuracy, consistency, and efficiency. In this comprehensive guide, we will explore the step-by-step process of creating a custom drill bit sharpening jig that will empower you to achieve professional-grade results in the comfort of your workshop.

Materials and Tools Required

• Steel or aluminum bar stock (1/2″ x 1″ x 6″)
• Angle grinder
• Vise
• Drill press
• 1/8″ drill bit
• 1/4″ drill bit
• 1/2″ drill bit
• Countersink bit
• Flat file
• Round file
• Sharpening stone or diamond wheel
• Measuring tape or ruler
• Safety glasses
• Gloves

Step-by-Step Guide

1. Prepare the Bar Stock

Cut the steel or aluminum bar stock to the desired length (6 inches is recommended). Use an angle grinder to smooth any burrs or sharp edges.

2. Mark and Drill the Holes

Measure and mark the center of the bar stock. Drill a 1/8″ hole at the marked point using a drill press. This hole will serve as the pivot point for the drill bit.

3. Countersink the Hole

Use a countersink bit to create a countersunk area around the 1/8″ hole. This will provide clearance for the head of the drill bit.

4. Drill the Drill Bit Holder

Drill a 1/2″ hole at one end of the bar stock, perpendicular to the 1/8″ hole. This hole will hold the drill bit.

5. Drill the Angle Adjustment Holes

Drill two 1/4″ holes at the other end of the bar stock, spaced approximately 2 inches apart. These holes will allow for angle adjustments during sharpening.

6. File the Groove

Use a flat file to create a groove between the 1/2″ hole and the 1/4″ holes. This groove will provide a guide for the drill bit during sharpening.

7. Sharpen the Drill Bit

Insert the drill bit into the 1/2″ hole and secure it with a bolt or set screw. Adjust the angle of the drill bit using the 1/4″ holes and tighten the bolts. Use a sharpening stone or diamond wheel to sharpen the drill bit according to the manufacturer’s recommendations.

Tips for Sharpening Drill Bits

• Use a slow speed when sharpening drill bits to prevent overheating.
• Sharpen both the cutting edges and the flute surfaces of the drill bit.
• Regularly check the sharpness of the drill bit by drilling into a scrap piece of material.
• Store drill bits in a dry and protected environment to prevent rust and dulling.
