LONGLIFE in-line drills

They can be used to drill out-line holes in chipboards (also laminated), wood and wood-like materials with multi-spindle drills and other machines with proper holders or adapters. Thanks to a bigger (longer) shaft made of tungsten carbide and proper geometry of drill, they have longer life than standard drills. They are a cheaper alternative for drill made fully of tungsten carbide.
