Review: Bohrerschleifscheibe - Original zu einem guten Preis
Review: No trae vástago - No trae vástago y el agujero no se adapta a ninguna medida standard, de manera que para usarlo en el taladro tienes que gastarte más dinero en un retenedor que, seguramente quedará descentrado. No he podido comprobar la eficacia de la piedra, pero me temo lo peor.

No trae vástago y el agujero no se adapta a ninguna medida standard, de manera que para usarlo en el taladro tienes que gastarte más dinero en un retenedor que, seguramente quedará descentrado. No he podido comprobar la eficacia de la piedra, pero me temo lo peor.

### ⭐⭐⭐⭐⭐ Bon
*by J***P on 22 February 2017*

Meule de qualité, le diamètre intérieur (12.7mm) est bien calibré. Dimensions générales bien régulières. Montée sur un mini touret pour affûtage des outils en acier rapide.
