• 加工石墨和玻璃纤维小孔表现出色。这种特殊头部设计钻头建议用在层铺式复合材料（除 KEVLAR 以外的），可获得精准的内孔尺寸。

• Excellent for small diameter holes in carbon fiber & fiberglass. This special drill is recomeded for use in most laminated composites other than straight Kevlar. The drill reamer will produce very clean accurate holes in the most difficult composite materials.
