Tork Craft Mini Grinding Stone 15.9Mm Disc 3.2Mm Shank

Description

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.

• Excellent for fine detail finishing where bench grinders are too large.
• Heat-Resistant.

The shank of the rotary cutter is securely locked in place by fitting
it in the corresponding collet or making use of a keyless chuck.

For improved grinding accuracy, make use of a flexible
shaft connected to the rotary engraver.

Rotation speed:

Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can be found on the packaging.

All materials react differently to speed and will need the tool bit to rotate slower.
It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.

The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
