advantage
1,Assembly:This product is connected to the tip end of H22 brazing rod, and the tip is required to be a car product (the small end is 18X7°), with an insertion depth of 30--33MM.
2,Sharpening:the brazing head should be dismantled by sliding hammer dismantler when it needs to be sharpened after being bluntly sharpened; it should be sharpened according to the correct sharpening method to restore the original geometrical structural parameters of the brazing head.
3,Applicable rocks: GL applies to quartzite, basalt and other kinds of particularly solid stones, with hardness of F=15--18; GA applies to granite, quartz porphyry, siliceous schist, stronger quartzite, the strongest sandstone and limestone, with hardness of F=12--15; GB applies to dense granite, very strong sandstone and limestone, quartz veins, and strong conglomerates, GB for dense granite, very solid sandstone and limestone, quartz veins, solid conglomerates, very solid iron ores. The hardness scale is F=10--12.
