Tork Craft Mini Grinding Stone 3.2Mm Cone 3.2Mm Shank

Description

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.

Features:

• Hard bonded structure.
• Precise control in small areas.
• Durable and holds shape longer.
• Works on hard and dense materials.
• 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.
