This Mini Abrasive Point is a versatile workshop powerhouse, specifically designed for blending contours, cleaning up heavy castings, and precision-shaping internal angles. Featuring a 12.7mm cone-shaped head, this tool provides a substantial, tapered surface that allows for rapid material removal on larger workpieces while still offering a pointed tip for reaching into tight V-grooves and recessed corners. It is an essential choice for fabricators who need to transition smoothly from aggressive grinding to refined finishing without switching tools.
The 12.7mm stone diameter offers a wide contact patch at the base of the cone, making it highly efficient for leveling weld fillets and smoothing out rough surface patches on steel, iron, and stone. The conical geometry is engineered to provide a 'forgiving' touch, allowing the user to roll the stone across irregular surfaces to eliminate high spots and burrs. Crafted from professional-grade abrasive grains, the stone is bonded to maintain its sharp, tapered profile and resist loading, ensuring consistent performance even under the heat of high-speed operation.
Mounted on a standard 3.2mm shank, this abrasive point is fully compatible with Dremel and other high-speed rotary tools. The tool is precision-balanced to ensure that the larger 12.7mm head rotates without excessive vibration, providing the steady control needed for both heavy stock removal and delicate edge blending. This stability is particularly beneficial when working on harder materials like hardened alloys or ceramics, where a chatter-free rotation is critical for a professional finish.
Whether you are an automotive enthusiast porting an intake, a sculptor refining a stone masterpiece, or a metalworker deburring a large fabrication, this 12.7mm cone stone delivers the perfect balance of reach and power. Its durable design and adaptable shape make it one of the most reliable accessories for achieving clean, uniform transitions in complex, hard-to-reach areas.

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.
