This Mini Diamond Point is an elite precision instrument designed for the most delicate etching and micro-grinding tasks on ultra-hard surfaces. Featuring an exceptionally fine 0.9mm pointed head coated in high-grade industrial diamond grit, it allows for surgical levels of detail that standard cutters simply cannot achieve. The sharp, conical geometry makes it the premier choice for pinpoint accuracy, whether you are signing a glass masterpiece, scribing identification on hardened steel, or detailing the finest crevices in a gemstone carving.
The 0.9mm diameter at the widest part of the point tapers down to a microscopic tip, offering unparalleled control for "stippling," fine-line engraving, and cleaning out tiny pits or inclusions. This miniature profile is specifically engineered for artisans who work under magnification, such as jewelers, watchmakers, and glass engravers. The diamond coating ensures that even at this minuscule scale, the tool bites into brittle materials like porcelain and crystal without causing the fractures or chipping associated with less precise bits.
To ensure the stability required for such high-finesse work, the tool is integrated with a 2.4mm shank. This standard-sized shank provides a rigid, vibration-dampening foundation that is essential when operating at the high RPMs needed for diamond abrasives. By fitting securely and concentrically into most professional rotary tools and high-speed engravers, the 2.4mm shank eliminates "chatter," granting you the steady hand and confidence required to execute complex patterns on expensive or fragile workpieces.
Built for remarkable longevity despite its small stature, this diamond-coated point is designed to maintain its sharp profile through repetitive professional use. The advanced bonding process ensures the diamond grit remains locked in place, providing consistent abrasive power and a smooth finish every time. Whether you are performing intricate filigree work or marking industrial components, this 0.9mm diamond point is the ultimate tool for achieving professional-grade micro-detail.

The shank is securely locked in place by fitting it in the corresponding collet or making use of a keyless chuck.
For improved accuracy, make use of a flexible shaft connected to the rotary tool.
Rotation speed:
Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can normally be found on the packaging.
All materials react differently to speed and will need the tool bit to rotate slower. It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.
The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
