This Mini Diamond Point is a high-precision abrasive tool engineered for vertical grinding, side-cutting, and shaping on the world&s hardest surfaces. Featuring a 2.4mm cylindrical head coated in industrial-grade diamond grit, it provides a consistent cutting surface along its entire length. This straight-walled geometry makes it the ideal choice for squaring off internal edges, deepening flat-bottomed channels, and smoothing the interior walls of pre-drilled holes in glass, stone, and ceramics.
The 2.4mm diameter of the cylinder matches the width of the shank, creating a streamlined "flush" profile that allows for excellent visibility and access into tight spaces. Whether you are etching straight lines into a glass vessel, refining a stone carving, or deburring hardened steel components, the diamond coating ensures a clean, uniform finish. This size is particularly favored by artisans and technicians who require a tool that can perform both detailed face-grinding and precise peripheral cutting.
To ensure maximum stability and a wobble-free performance, the tool is built with a 2.4mm shank. This industry-standard sizing ensures a secure, concentric fit in most professional rotary tools and high-speed engravers. By providing a rigid, one-to-one ratio between the head and the shank, the tool minimizes vibration and "chatter," granting you the steady hand necessary for maintaining perfectly straight vertical walls and sharp 90-degree transitions.
Designed for exceptional longevity, this diamond-coated cylinder is built to withstand the intense heat and friction of continuous grinding. The high-quality diamond bonding ensures that the abrasive surface remains sharp and effective even after repetitive use on brittle or dense materials. From jewelry repair and lapidary work to industrial marking on hardened alloys, this 2.4mm cylindrical diamond point is an essential asset for any craftsman demanding geometric precision.

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.
