Sheet of stocked items; Dimensions Cutting conditions; Applications Line Up, Re-grinding 02WNSB0000 L/D=2 TH ( Without oil hole"') O Re-grinding (i) Performance may deteriorate to 20%~40% of the initial performance due to the method of regrinding and re-coating. Without coating after regrinding, performance may be further reduced and cause chipping or breakage of the drill. It is recommended that you ask us to regrind and recoat your drill to maintain its performance. 2) When regrinding yourself, finish the cutting edge surface so that its roughness is 1.6S or less and the lip height difference...
