Burin à froid en acier chrome-vanadium Bellota 8251 pour saignées et coupe de tôle à froid Le burin est l'outil polyvalent par excellence de la caisse à outils : il ouvre des saignées, assainit les murs, élimine les restes de béton et coupe même la tôle à froid. Le Bellota 8251 y parvient grâce à un acier chrome-vanadium traité zone par zone pour durer et pour travailler en toute sécurité.
Il est fabriqué en acier chrome-vanadium de première qualité, avec des zones de frappe trempées par induction et un revenu intégral. Le traitement thermique est différencié selon les trois zones de travail : la tête, pour votre sécurité (elle réduit le risque d'éclats) ; la pointe, pour une plus grande durée de vie ; et le corps, pour réduire les vibrations lors de la frappe. Les pointes sont rectifiées, biseautées et vernies.
