Thermal drilling
Flowdrill Inc. provides a video demonstration of its thermal drilling process. The company produces tungsten-carbide bits and roll-form taps to thermal drill and then thread holes in malleable materials.
Holemaking alternatives
Several alternatives mechanical drilling make sense when the application is right.
Riding herd on runout
When drilling and milling, controlling runout is critical to maximize tool life and reduce cost per hole.
Deep and steady
A long boring tool can cause vibration, so deep holes can be deep trouble. But several strategies can minimize vibration.
Custom connection
Custom tools help aerospace part makers meet demanding specs.
