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.
