Mini Diamond Point 4.4mm Ball 2.4mm Shank
Shape: Ball
Tip Diameter: Ø4.4mm
Shank Diameter: Ø2.4mm
This Mini Diamond Point is a high-performance abrasive tool engineered for precision grinding and shaping on the toughest surfaces. Featuring a substantial 4.4mm ball-shaped head coated in industrial-grade diamond grit, it excels at material removal where standard steel cutters would struggle. The spherical geometry provides a smooth, rounded contact point, making it the perfect choice for creating larger concave depressions, rounding off sharp internal edges, or hollowing out sections in stone, glass, and ceramics.
The 4.4mm diameter of the diamond head offers a generous abrasive surface area, allowing for efficient work on broader details without sacrificing the control needed for artisanal projects. Whether you are sculpting stone, etching thick glass, or deburring hardened steel, this larger ball point provides a consistent, professional finish. It is a favorite among lapidary artists and glass workers who need a reliable tool for both shaping and smoothing out rougher textures.
For maximum stability during high-speed operation, the tool is integrated with a 2.4mm shank. Despite the larger 4.4mm head, this standard-sized shank ensures a secure and concentric fit in most professional rotary tools and high-speed engravers. The precision-machined shank is designed to minimize vibration and "chatter," granting you the steady hand required to work safely on delicate or brittle workpieces like crystal or porcelain.
Built for exceptional durability, this diamond-coated bit is designed to withstand the intense heat and friction of heavy-duty grinding tasks. The high-quality bonding process ensures the diamond grit remains sharp and effective through repeated use, delivering reliable results across a wide range of industrial and creative applications. From refining jewelry castings to detailed masonry work, this 4.4mm ball point is a versatile powerhouse for any workshop.

The shank is securely locked in place by fitting it in the corresponding collet or making use of a keyless chuck.
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.
