The Beadsmith Motorized Bead Reamer Cordless — 2 AA Battery Handpiece with 3 Diamond Tips for Glass, Ceramic & Stone

The Beadsmith Motorized Bead Reamer is a cordless, battery-powered handpiece with three interchangeable diamond grit tips designed to safely enlarge, smooth, and refine bead holes in glass, ceramic, stone and more.

If you work with beads and jewellery components, consistent hole size and burr-free edges are essential for clean stringing and secure finishes. This compact, ergonomic tool runs on two AA batteries and delivers up to 10,000 rpm through diamond-encrusted reamer tips that remove material precisely without cracking delicate beads. The set includes a clear storage tube for tips and three shapes made for widening holes, softening rough rims, and finishing edges on a wide range of materials.

How does the cordless motor help when preparing beads?

The battery-powered motor provides steady rotation so you can control material removal and avoid overworking fragile beads. Its lightweight handle and fast spin speed let you refine holes quickly while keeping a gentle touch for delicate substrates.

• Runs on 2 AA batteries (not included) for portable, cord-free use
• 10,000 rpm motor for efficient cutting and smoothing
• Ergonomic, lightweight handpiece for precise control
• Clear storage tube protects tips and keeps them organized

Which diamond tips are included and when should I use each?

The kit contains three diamond encrusted tips: two tapered reamers (2" and 3" lengths) with 2.3mm tips and a 45-degree edging point for rounding and finishing. Use the tapered tips to enlarge small holes and the edging tip to remove burrs and soften cut rims before stringing.

• 2" tapered reamer — for moderate enlargement and access to tighter beads
• 3" tapered reamer — for deeper holes and thicker beads
• 45-degree edging point — smooths rough edges and prevents thread abrasion
• Industrial-grade diamond grit for long-lasting, precise performance

What materials can this bead reamer work on without damaging them?

Diamond grit is suitable for a broad range of hard and brittle bead materials because it abrades without applying heavy pressure. The reamers are effective on glass, ceramic, stone, shell, pearl, gemstone and some metals and plastics when used with a steady, light touch.

• Glass and crystal beads — carefully enlarge and remove chips
• Ceramic and porcelain — refine drilled holes and edges
• Gemstone, shell, and pearls — smooth burrs with minimal material loss
• Wood, plastic, and some metals — reshape or deburr with appropriate pressure

How do I get consistent, professional results every time?

Work slowly, keep the handpiece steady, and use short passes to avoid overheating or cracking delicate materials. Check progress frequently and switch to the edging tip for a final pass to remove any remaining sharpness around the hole.

• Rotate the bead or reamer gently; avoid forcing the tip through a hole
• Use light pressure and multiple passes for controlled removal
• Clean and store tips in the included clear tube to preserve grit
• Replace batteries when motor slows to maintain consistent rpm

Who is this for: The Beadsmith Motorized Bead Reamer is aimed at hobbyists, beading professionals, and jewellery makers who need a compact, portable solution for resizing bead holes and removing burrs. It suits anyone working with glass, ceramic, stone, shell, pearls, gemstones, or mixed-material components who wants precise control, repeatable results, and durable diamond tips in a simple, cordless package.
