Mini Abrasive Point 12.7mm Round Point 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø6.4mm
Shape: Round Point
This Mini Abrasive Point is a versatile finishing tool designed for intricate sculpting, internal contouring, and precision deburring. Featuring a round point shape (also known as a ball or spherical profile), this stone is the ideal choice for creating concave cuts, cleaning up circular indentations, and smoothing out irregular surfaces that flat stones simply cannot reach.
The tool is engineered with a 6.4mm stone diameter on a 12.7mm head length, providing a elongated spherical geometry that allows for multi-angle contact. This "round point" profile is exceptionally forgiving, making it perfect for blending transitions between different surfaces or removing material from the inside of curved workpieces without leaving sharp edges. Its high-grade abrasive composition ensures a consistent finish on a wide variety of materials, from hardened steels and alloys to ceramics and glass.
Mounted on a standard 3.2mm shank, this abrasive point is fully compatible with Dremel and other high-speed rotary tools. The balance between the 6.4mm head and the slender shank provides a streamlined "neck," allowing the tool to reach deep into recessed areas while maintaining high visibility of the workpiece. The precision-bonded construction ensures stable, vibration-free performance even at high RPMs, giving you the steady control needed for fine-detail artistic or mechanical work.
Whether you are a jeweler refining a setting, a woodcarver adding texture to a sculpture, or a technician deburring a complex casting, this round point stone offers the delicate touch and durability required for professional results. Its ability to grind from almost any angle makes it one of the most hardworking and adaptable shapes in any rotary tool kit.

The shank of the rotary cutter 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.
