1.5mm & 2mm Diamond Drill Bit Set, 10-Piece with 2 Collets – Sea Glass & Jewelry

• Two Sizes: 5 bits at 1.5mm and 5 bits at 2mm for different projects.
• 2 Collets Included: One collet for each size, so the bits mount directly on your rotary tool.
• Diamond-Coated Twist Tips: Drill clean small holes in glass, stone and shells without cracking.
• 135° Point: Twist-tip design helps start holes accurately.
• Built for Jewelry: Ideal for beading, pendants, sea glass and small decorative pieces.

• Materials: Sea glass, glass, seashells, gemstones, stone, rock, ceramic and porcelain.
• Tools: Rotary tools such as Dremel, flex shafts, drill stands and other lapidary equipment, using the included collet.

• Fit the Collet: Put the included brass collet in your rotary tool, insert the bit and tighten it securely.
• Keep It Wet: Drill with the piece and bit under water or with a steady drip. Water keeps the tip cool, protects the piece and makes each bit last longer.
• Start at an Angle: Begin at an angle to cut a small notch so the bit doesn't walk, then slowly bring the tool upright.
• Light Pressure, Low Speed: Let the diamond do the work. Pushing hard or running fast and dry wears the coating quickly and can crack delicate pieces.

• Sea Glass Jewelry: Drill beach glass for pendants, necklaces and earrings.
• Shells and Gemstones: Make hanging holes in seashells, gemstones and small stones.
• Beads and Bracelets: Drill beads and small pieces for bracelets and custom jewelry.
• Crafts and Keepsakes: Turn beach finds into keepsakes and handmade gifts.

Q: What sizes are in the set?
A: Five 1.5mm bits (about 0.059 inch) and five 2mm bits (about 0.079 inch).
Q: Will they fit my Dremel?
A: Yes. The set comes with 2 collets so the bits mount directly on Dremel and other rotary tools.
Q: Which size should I use?
A: Use 1.5mm for fine holes in small pieces and 2mm where you need a little more room for jump rings or cord.
Q: Do I need to use water?
A: Yes. Drill wet, with the piece under water or a steady drip. Water keeps the diamond coating cool, protects delicate materials from cracking and makes each bit last longer.
Q: How do I stop the bit from slipping on glass?
A: Start at an angle to cut a small notch, then bring the tool upright slowly once the hole has started.
Q: How long does each bit last?
A: Small diamond bits wear with use, which is why they come in multi-bit sets. Drilling wet, at low speed and with light pressure keeps each tip cutting longer.
Q: What materials can I drill?
A: Sea glass, glass, stone, semi-precious stones, shells and porcelain.
