Allen Key (Hex Key) 6.0 mm

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.

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.

Application:

• Max rated RPM: 35 000 RPM
• Sharpening chisels, knife edges cutting tools and more.
• Removes sharp edges on cut metal parts.
• Refines contours in metal or stone.
• Removes rust, weld spatter, and surface coating.
• Ceramics: 20 000 – 30 000 RPM
• Glass: 20 000 – 30 000 RPM
• Stonework: 20 000 – 25 000 RPM

Shank Diameter: Ø3.2mm
Stone Diameter: Ø5.5mm
Profile: Cone

This Mini Grinding Stone is the ultimate precision tool for ultra-fine detail work and delicate finishing in
confined spaces. Its specialized geometry is specifically designed for craftsmen who need to reach the smallest
gaps, making it a critical addition to any precision-focused toolkit.

The tool features a 3.2mm cone-shaped head, providing a sharp, tapered profile that allows for pinpoint accuracy.
This slim, conical design is ideal for enlarging small holes, cleaning up intricate carvings, and smoothing tight
internal angles where larger stones simply cannot fit. It performs exceptionally well on hard materials such as
alloy steel, glass, and ceramics.

Equipped with a standard 3.2mm (1/8′) shank, this grinding stone offers seamless compatibility with most high-speed
rotary tools. The matching diameter of the head and shank ensures a streamlined profile, allowing the tool to pass
through narrow openings for deep-reach applications. This design provides excellent stability and minimizes run-out,
ensuring your work remains precise even at high speeds.

Whether you are performing delicate jewelry repairs, detailed model engineering, or fine metal etching, this
cone-shaped stone provides the control and durability required for professional results. Its high-grade abrasive
grit maintains a sharp cutting edge, ensuring consistent performance and a smooth finish on every workpiece.
