What To Know
- Hand drilling uses a hand-held drill with a chuck, while power drilling employs an electric drill.
- Drill at a very slow speed and use a light touch to avoid chipping or damaging the gemstone.
- What should I do if I break a drill bit.
Drilling jewelry is a captivating craft that allows you to create unique and exquisite pieces. Whether you’re a seasoned artisan or just starting your jewelry-making journey, this guide will provide you with all the essential knowledge and techniques you need to master this art form.
Understanding the Basics
Types of Drill Bits
The choice of drill bit depends on the material you’re drilling. For metal, use tungsten carbide or cobalt drill bits. For gemstones, diamond-coated drill bits are ideal. For glass, carbide or diamond-coated bits are recommended.
Drilling Techniques
There are two main drilling techniques: hand drilling and power drilling. Hand drilling uses a hand-held drill with a chuck, while power drilling employs an electric drill. Both techniques require precision and care.
Safety Precautions
Jewelry drilling involves sharp tools and potential hazards. Always wear safety glasses, gloves, and a mask. Secure your workpiece firmly in a vise or clamp to prevent it from moving.
Drilling Metal Jewelry
Step 1: Mark the Drilling Point
Use a fine-tipped marker to indicate the exact location where you want to drill.
Step 2: Choose the Right Drill Bit
Select a drill bit that is the same diameter as the desired hole size.
Step 3: Lubricate the Drill Bit
Dip the drill bit in oil or drilling lubricant to reduce friction and prolong its life.
Step 4: Drill Slowly and Gradually
Start drilling at a low speed and gradually increase it. Apply constant, gentle pressure to avoid breaking the drill bit.
Drilling Gemstone Jewelry
Step 1: Prepare the Gemstone
Place the gemstone in a setting or secure it with wax to prevent it from moving.
Step 2: Use a Diamond-Coated Drill Bit
Diamond-coated drill bits are essential for drilling gemstones as they can cut through hard materials effectively.
Step 3: Drill at a Slow Speed
Drill at a very slow speed and use a light touch to avoid chipping or damaging the gemstone.
Drilling Glass Jewelry
Step 1: Use a Carbide or Diamond-Coated Drill Bit
Carbide or diamond-coated drill bits are recommended for drilling glass.
Step 2: Dip the Drill Bit in Water
Keep the drill bit wet with water to lubricate it and prevent overheating.
Step 3: Drill at a High Speed
Drill at a high speed to prevent the glass from chipping or cracking.
Finishing Touches
Step 1: Deburr the Hole
Use a small file or sandpaper to smooth out any sharp edges around the drilled hole.
Step 2: Clean the Jewelry
Remove any debris or lubricant from the jewelry using a soft cloth and jewelry cleaner.
Troubleshooting
Drill Bit Breaks
If the drill bit breaks, stop drilling immediately and remove the broken piece carefully. Use a new drill bit of the same diameter.
Jewelry Cracks
If the jewelry cracks during drilling, it may be due to excessive pressure or drilling at too high a speed. Use a smaller drill bit and drill more slowly.
Hole is Too Small
If the drilled hole is too small, use a slightly larger drill bit and re-drill. Be careful not to drill too large a hole.
