🔧 What it does & how to use

Diamond burs are used for engraving, grinding, shaping and fine detail work on hard materials such as glass, stone, ceramic and metal. They're popular with hobbyists, jewellers and craft workers for precision jobs that ordinary steel bits can't handle, and this 30-piece set gives a good spread of shapes and grit points for different tasks.

• Fit the bur: insert the shank fully into your Dremel or rotary tool's chuck or collet.
• Secure it: tighten the collet nut so the bur runs true without wobble.
• Set the speed: start on a low-to-medium speed, especially on delicate materials like glass or stone.
• Work gently: let the diamond grit do the cutting — apply light, steady pressure rather than forcing it.
• Keep it cool: for glass or stone, a little water helps reduce heat and dust.
• Swap as needed: change burs for different shapes/grits depending on the detail or finish required.
