Shank Diameter: Ø3.2mm
Stone Diameter: Ø25.4mm
Profile: Wheel

This Mini Grinding Stone is a high-performance abrasive wheel designed for efficient surface leveling and edge
treatment. The wheel profile provides a broader contact area than pointed stones, making it the go-to choice for
tasks that require uniform material removal across larger sections of a workpiece.

The tool features a 25.4mm (1 inch) wheel-shaped head, which is ideal for creating clean, straight slots or for
grinding flat against a surface. This disc-like geometry is particularly effective for side-grinding, allowing you
to smooth out rough edges, remove rust, or sharpen flat blades with ease. It is engineered to handle a wide range of
materials, including carbon steel, stainless steel, and various non-ferrous alloys.

Despite its larger head diameter, it is built on a standard 3.2mm (1/8′) shank. This ensures it remains compatible
with most high-speed rotary tools and Dremel handpieces. The design is balanced to maintain stability at high
speeds, though the larger diameter allows for a higher peripheral speed, which translates to faster cutting and a
smoother finish with less effort.

Whether you are finishing a metal fabrication project, restoring old hardware, or deburring a long cut, this
wheel-shaped grinding stone offers the surface area needed for professional productivity. Its durable abrasive bond
is designed to resist clogging and wear, ensuring the wheel retains its diameter and effectiveness over multiple
uses.

Shank Diameter: Ø3.2mm
Stone Diameter: Ø9.5mm
Shape: Ball

This Mini Grinding Stone is a specialized abrasive tool designed for intricate contouring, hollow-grinding, and
internal radius smoothing. Featuring a 9.5mm ball-shaped head (spherical profile), this bit is the ultimate choice
for creating uniform concave depressions and cleaning up rounded indentations where flat or pointed stones would
leave unwanted gouges. Its perfectly round geometry allows for multi-directional grinding, making it exceptionally
easy to blend transitions on irregular surfaces.

The 9.5mm stone diameter provides a substantial contact area for a spherical bit, allowing for efficient material
removal while still maintaining the delicate touch required for precision work. Whether you are deburring the inside
of a pipe exit, carving smooth channels in wood or stone, or refining the cast lines on metal components, the
rounded profile ensures a consistent finish from any angle. The high-grade abrasive composition is engineered to
stay cool and resist loading, ensuring the ball maintains its spherical accuracy throughout its life.

Equipped with a standard 3.2mm shank, this ball stone is fully compatible with Dremel and other high-speed rotary
tools. The precision-bonded construction ensures the 9.5mm head remains perfectly balanced at high RPMs, providing a
smooth, chatter-free experience. This stability is vital when performing detailed ‘free-hand’ work, as it gives the
user the steady control needed to follow complex curves and interior contours without the tool skipping or jumping.

Ideal for jewelers, woodcarvers, and metal fabricators alike, this 9.5mm ball grinding stone is a must-have for any
project involving curved geometries. Its ability to create smooth, rounded finishes and reach into spherical
recesses makes it one of the most versatile shapes for artistic refinement and mechanical deburring.

Shank Diameter: Ø3.2mm
Stone Diameter: Ø15.9mm
Shape: Disc

This Mini Grinding Stone is a versatile and efficient abrasive tool designed for surface leveling, edge smoothing,
and material blending. Featuring a 15.9mm disc-shaped head, this bit provides a flat, wide grinding surface that is
far more effective for treating larger areas than pointed or cylindrical stones. The disc profile allows you to
apply consistent pressure across a broader plane, making it the ideal choice for removing rust, smoothing out weld
seams, or leveling high spots on metal, glass, and stone workpieces.

The 15.9mm stone diameter offers a high peripheral speed, which translates to faster material removal and a cleaner
finish. Unlike thicker wheels, this slim disc geometry allows you to reach into narrow slots or perform precise
side-grinding with better visibility of the contact point. The stone is crafted from premium-grade abrasive material
that is engineered to stay sharp and resist loading, ensuring that the disc maintains its flat geometry even during
extended use on hardened alloys or ceramics.

Equipped with a standard 3.2mm shank, this disc stone is fully compatible with Dremel and other high-speed rotary
tools. The precision-bonded construction ensures the disc remains perfectly centered and balanced at high RPMs,
which is critical for preventing vibration and ‘chatter’ marks on your finished surface. This stability gives the
user exceptional control, whether you are performing heavy-duty stock removal or light surface preparation before a
final polish.

Whether you are a metal fabricator cleaning up a workpiece, a restoration specialist removing oxidation from antique
hardware, or a hobbyist refining a DIY project, this 15.9mm disc grinding stone is a must-have accessory. Its
combination of surface area and precision maneuverability makes it an indispensable tool for achieving
professional-grade, flat finishes in any workshop environment.

Shank Diameter: Ø3.2mm
Stone Diameter: Ø6.4mm
Shape: Cone

This Mini Grinding Stone is a precision-engineered abrasive accessory designed for detailed carving, internal
deburring, and refining tight geometries. Featuring a 6.4mm cone-shaped head, this tool provides a slim, tapered
profile that strikes the perfect balance between the ultra-fine reach of a micro-bit and the material-removal power
of larger stones. It is particularly effective for smoothing out internal radii, cleaning up small castings, and
tapering the edges of holes in hard materials.

The 6.4mm stone diameter allows the tool to fit into narrow channels and acute angles that larger bits cannot
access, while the pointed tip offers pinpoint accuracy for localized grinding. This conical shape is ideal for
‘v-grooving’ or creating precise countersinks in metals, glass, and ceramics. The high-quality abrasive grains are
bonded to resist premature wear, ensuring that the stone retains its sharp, tapered edge even when subjected to the
high-speed friction required for hardened steel or alloy work.

Equipped with a universal 3.2mm shank, this stone is compatible with almost all high-speed rotary tools, including
Dremel models. The precision alignment between the 6.4mm head and the 3.2mm shank ensures a concentric, wobble-free
rotation, which is critical for fine-detail work where a steady hand is required. This stability reduces user
fatigue and prevents the tool from ‘jumping’ out of delicate grooves, allowing for a professional, uniform finish on
every workpiece.

Whether you are an artist working on a detailed sculpture, a gunsmith refining a small component, or a hobbyist
cleaning up a 3D-printed part, this 6.4mm cone grinding stone is an indispensable tool. Its versatility makes it
suitable for both aggressive material removal and light touch-ups, providing a smooth transition between rough
grinding and final polishing in any workshop setting.
