This Mini Grinding Stone is a high-precision hybrid accessory designed for professional-grade deburring, carving, and surface finishing. Featuring a 6.4mm stone diameter, this bit utilizes a unique Cylindrical-Cone profile (often referred to as a tapered cylinder), which combines the flat-wall grinding capabilities of a cylinder with the pointed precision of a cone. This dual-purpose shape makes it incredibly versatile for cleaning up internal pipe walls while simultaneously reaching into tight corners or deburring complex hole exits.
Crafted from high-performance abrasive grains, this stone is engineered to handle a wide range of materials, including hardened steel, non-ferrous metals, ceramics, and glass. The 6.4mm head provides enough surface area for efficient material removal on flat planes, yet is slim enough to navigate narrow channels and intricate details. Its robust construction ensures that the stone maintains its profile even under heavy pressure, preventing the rounding of the tip that often occurs with lower-quality bits.
Mounted on a standard 3.2mm shank, this tool is universally compatible with Dremel and other high-speed rotary tools. The precision-centered shank is designed to eliminate vibration, allowing for the steady, surgical control necessary for fine-detail work. This lack of 'run-out' ensures a smoother finish and reduces hand fatigue during long sessions of polishing or grinding.
Whether you are a mechanic porting a small engine component, a jeweler shaping a custom piece, or a DIY enthusiast refining a 3D-printed model, this 6.4mm Cyl./Cone stone is a fundamental addition to your toolkit. Its ability to switch between flat-surface leveling and point-grinding without changing bits saves time and ensures a seamless, professional finish across every part of your workpiece.

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 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.
