收藏: Sintered Diamond Burs
Sintered Diamond Burs are professional-grade rotary carving tools with diamonds distributed throughout the full depth of the metal matrix — continuously exposing fresh cutting points as the bur wears for consistent, long-life performance on hard stone, glass, and gemstones. Unlike electroplated burs with a single surface diamond layer, sintered burs maintain their cutting efficiency throughout their working life, making them the preferred choice for serious lapidary carvers and engravers who demand reliable, repeatable results.
Key Features
- Full-depth sintered diamond matrix — Fresh cutting points continuously exposed as the bur wears
- 5–10× longer life — Significantly outlasts electroplated burs on hard stone and glass
- Consistent cutting performance — Maintains efficiency from first use to last
- Compatible with standard rotary tools — Dremel, flex shaft machines, and pendant drills
- Wet use design — Use with water for maximum bur life and dust suppression
Applications
- Stone carving and sculpture on agate, jasper, quartz, and hard minerals
- Gemstone engraving and surface texturing
- Glass carving and decorative engraving
- Lapidary detail work and relief carving
- Ceramic and porcelain carving

Frequently Asked Questions
-
Q: Why choose sintered diamond burs over electroplated burs?
A: Sintered burs have diamonds throughout the full matrix depth — as the surface wears, fresh diamonds are exposed. This gives sintered burs 5–10 times longer service life than electroplated burs on hard stone and glass. For professional carvers doing high-volume work, sintered burs deliver a significantly lower cost per hour of carving. -
Q: Should sintered diamond burs be used wet or dry?
A: Always use wet. Apply water continuously during carving to cool the bur and stone, prevent heat damage, and suppress stone dust. A small water drip or spray bottle works well for rotary tool carving. Never run sintered diamond burs dry — heat buildup reduces bur life and can crack heat-sensitive stones. -
Q: What rotary tools are sintered diamond burs compatible with?
A: Sintered diamond burs with 1/8" (3mm) shanks are compatible with Dremel-style rotary tools, flex shaft machines, pendant drills, and most standard rotary carving tools. Always verify the shank diameter matches your tool’s collet size before ordering.
