Shank Diameter: Ø3.2mm
Stone Diameter: Ø6.4mm
Shape: Cylindrical cone

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.

Shank Diameter: Ø3.2mm
Stone Diameter: Ø9.5mm
Profile: Cylinder

This Mini Grinding Stone is a high-performance abrasive tool specifically engineered for precision surface finishing
and material removal. The cylindrical profile makes it an indispensable asset for tasks that require flat-surface
grinding and the cleaning of straight edges or interior walls.

The tool features a 9.5mm cylindrical head, a diameter that strikes an ideal balance between maneuverability and
surface coverage. This flat-topped shape is perfect for smoothing out welds, sharpening blades, or leveling surfaces
on a variety of tough materials, including stainless steel, cast iron, and non-ferrous metals.

Designed for seamless integration into your existing kit, it comes with a standard 3.2mm (1/8′) shank. This ensures
full compatibility with Dremel and other popular high-speed rotary tools, providing a secure, vibration-free fit
that allows for maximum control during high-RPM operation.

Shape: Wheel

This Mini Grinding Stone is a precision-engineered abrasive wheel designed for controlled surface smoothing and edge
refinement in tight or delicate areas. The wheel geometry provides a flat contact surface, making it far more
efficient than rounded bits for tasks that require a uniform level finish or the cleaning of narrow grooves and
slots.

The tool features a 10.3mm wide wheel-shaped head with a 8.2mm stone diameter, offering a compact disc profile that
excels at side-grinding. This specific sizing allows for high maneuverability, enabling you to smooth down sharp
edges, remove small burrs, and sharpen flat blades with exceptional accuracy. Its high-grade abrasive composition is
