MINI GRINDING STONE 6.4MM CYL./CONE 3.2MM SHANK

Description

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.
