Flute form, point thining and compound lead construction are all patented technologies developed by OSG to make this drill do what no other parabolic HSS-Co drill can. The addition of our exclusive WXL coating technology makes non-peck drilling repeatable, even in the longest of production runs.","Point Angle - Degree (α)":"120","Product Overview":"20X Diameter Lengths, HSS-CO, WXL Coating","Diameter - Letter Size (D)":"E","Shank Diameter - Metric (d)":["1.6","1.8","2","2.1","2.2","2.3","2.4","2.5","2.6","2.7","2.8","2.9","3","3.1","3.2","3.3","3.4","3.5","3.7","3.8","4","4.1","4.2","4.3","4.5","4.6","4.8","5","5.1","5.2","5.5","5.7","5.8","6","6.5","7","7.5","8","8.1","8.2","8.5","9","10","11","12"],"Diameter-Sizes":"0.06299\" - 14.288mm","Flute-Sizes":"38mm - 328mm","Neck-Sizes":"-","Taper-Sizes":"-","Overall-Sizes":"85mm - 378mm","Shank-Sizes":"1.6mm - 0.65625\"","Friendly Name":"1770","CategoryBrand":"V-SERIES"}
