Puntero Octogonal de Acero Cromo Vanadio Bellota 5821 para Trabajar la Piedra y Practicar Aperturas Abrir un hueco en un muro, desbastar piedra o quitar restos de hormigón pide una herramienta que aguante golpe tras golpe sin despuntarse.

Está fabricado en acero cromo vanadio de máxima calidad, con las zonas de golpeo templadas por inducción y revenido integral. El tratamiento térmico es diferenciado en las tres zonas de trabajo: la cabeza, para tu seguridad (reduce el riesgo de esquirlas); la punta, para una mayor duración; y el cuerpo, para reducir las vibraciones al golpear. Las puntas van rectificadas, biseladas y barnizadas.
