💡 What makes carbide Forstner bits so handy for rough hardwood drilling?
Cutting through dense timber requires a sharp edge that resists heat buildup during deep borings. Here is why pros pick this setup:
- Tungsten carbide tips maintain a razor sharp perimeter when boring cupboard hinges
- Flat bottom design seals cleanly against MDF sheets for flush shelf pin placement
- Stepped shank alignment lowers binding torque on thick plywood panels
- Quick chip evacuation channels keep the flute clear during extended router sessions
