Product Information
Flat bottom drill is a productivity tool that combines two operations in one which are eliminates the 180° end mill in flat-bottom drilling or when preparing an inclined or curved surface for drilling and after full cylindrical engagement, the drill runs at normal solid carbide drilling parameters. The B707 FBS series with the new uncoated KN15 grade now offers the same advantages for drilling in non-ferrous materials, such as aluminium, copper and brass.
