Mini Grinding Stone 4.8mm Cyl. 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø4.8mm
Shape: Cylinder
This Mini Grinding Stone is a precision instrument designed for fine-detail metalworking, internal deburring, and slot cleaning. Featuring a cylindrical shape, this tool provides a perfectly flat side-profile that is essential for maintaining straight edges and squaring internal corners. Unlike tapered bits, the 4.8mm cylinder ensures a uniform diameter across the entire length of the head, making it the superior choice for cleaning up the inside of small pipes or refining linear channels without tapering the workpiece.
The 4.8mm stone diameter is specifically sized for narrow-access tasks where accuracy is paramount. This slim profile allows the bit to reach into tight apertures and small bore holes while still offering enough surface area for effective material removal. Crafted from high-performance abrasive material, the stone is engineered to resist heat and clogging, ensuring it retains its sharp, flat-walled geometry even when working on hardened steel, non-ferrous alloys, or glass.
Equipped with a universal 3.2mm shank, this cylindrical stone is fully compatible with Dremel tools and other high-speed rotary handpieces. The precision-centered design ensures a stable, vibration-free rotation at high speeds, which is critical for achieving a smooth, professional finish on delicate components. This stability prevents the "chatter" marks often associated with lower-quality bits, giving you total control over the depth and consistency of your grind.
Whether you are a mechanic cleaning up a small port, a jeweler squaring a setting, or a technician deburring a precision-machined part, this 4.8mm cylindrical stone offers the exactness and durability your projects demand. Its ability to provide a clean, flat-wall finish makes it an essential component for any toolkit focused on precision mechanical repair or detailed fabrication.

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.
