*Usage over the maximum rotational speed may result in breakage of the head and shaft.
*The tool has high grinding power even at low rotational speed. Start from 1000 min⁻¹, and then gradually increase the rotational speed.
*Apply the stone lightly on the workpiece so that the deflection of the shaft is about 0.5mm (approximately 1N of force is exerted at this deflection).
Use the ball head size slightly larger than the edge size, and deburr by pressing the head against it.
Use the ball head type that is slightly smaller than the edge size, and deburr by contouring.
Use the cylinder-shaped head type and deburr by pressing it against the hole while moving it up and down.
Use the ball head type that is slightly larger than the groove width, and deburr by moving the head back and forth across the groove.
Ideal for removing hard-to-reach burrs generated at the bottom of the groove.
Ball type and cylinder type:
There are 5 diameter sizes available: φ3mm, φ4mm, φ5mm, φ6mm and φ10mm.
Three different levels of roughness are available: Equivalent grits of #220, #400 and #800.
For better surface roughness: #800
For higher grinding power: #220
*The disc type is only available in #220
The tool has high grinding power even at low rotational speed.
Start from 1,000 min⁻¹, and then gradually increase the rotational speed.
*The tool may break off when being processed beyond maximum rotational speed.
Never use at a rotational speed exceeding maximum rotational speed.

Apply the stone lightly on the workpiece so that the deflection of the shaft is about 0.5mm (approximately 1N of force is exerted at this deflection).
Start from 300mm/min. There is no upper limit of use.
Ideal for deburring and polishing front and back of cross holes, grooves and areas that are deep inside the workpiece.
The spring steel flexible shaft absorbs vibrations which makes soft contact with the surface possible.
