02MATERIALS

Diamond tips for hard surfaces

Each bit features a diamond coating that maintains its edge against abrasive materials like cast iron, stainless steel and marble. The double-groove structure creates crossed lines, which helps manage heat and debris when working with lower-density objects, ensuring a smoother finish on delicate substrates.

03FIT

Standard 3mm shank compatibility

With a 3mm handle diameter, these burs slot directly into most standard rotary tools without requiring adapters. The 45mm total length provides enough reach for detailed interior work while remaining manageable for fine control. The 6mm head diameter offers a balanced surface area for both broad shaping and intricate detailing.

04STORAGE

Secure storage in a clear case

The twenty heads arrive in a dedicated plastic case that keeps them organised and protected from knocks. This is particularly useful for a mixed-material set, as it prevents the diamond tips from chipping against other tools. The compact carton measures 20 x 11 x 11 cm, making it easy to store in a drawer or toolbox.
