Mini Grinding Stone 15.9mm Cone 3.2mm Shank
Shank Diameter: Ø3.2mm
Stone Diameter: Ø15.9mm
Shape: Cone
This Mini Grinding Stone is a high-performance abrasive tool designed for aggressive material removal and precision shaping in contoured areas. Featuring a robust 15.9mm cone-shaped head, this bit provides a versatile, tapered profile that allows you to transition seamlessly from broad surface grinding at the base to finer, detailed work at the tip. It is an ideal choice for smoothing out weld fillets, cleaning up heavy castings, and enlarging holes where a standard cylindrical stone might be too restrictive.
The 15.9mm stone diameter offers a larger contact patch than standard micro-bits, significantly reducing the time required to level uneven surfaces or remove heavy burrs from hardened steel, iron, and stone. Despite its larger head size, the conical geometry ensures that you can still reach into tight angles and V-grooves with ease. The high-grade abrasive grit is specifically bonded to withstand the higher torque and heat generated during heavy-duty grinding, ensuring the tool maintains its sharp cutting profile throughout its lifespan.
Equipped with a standard 3.2mm shank, this grinding stone is fully compatible with most high-speed rotary tools, including Dremel models. To ensure safety and precision, the stone is engineered for optimal balance, minimizing vibration even when operating at high RPMs. This stability allows for smoother handling and prevents "walking" on the workpiece, giving you the confidence to perform heavy stock removal or delicate edge blending with equal success.
Whether you are a metalworker smoothing out a fabrication, a sculptor refining a stone carving, or an automotive enthusiast porting an engine component, this 15.9mm cone stone provides the perfect blend of power and maneuverability. Its durable construction and efficient shape make it a go-to tool for any project requiring significant material cleanup in hard-to-reach spaces.

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.
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.
