Boring bit with threaded shank mounted directly in the boring spindle
Length comparison: Dowel drills with threaded shank have a deeper boring depth than a comparable boring bit with cylindrical shank mounted in drill adaptors while having a lower overhang A with regard to the boring spindle.
Chipboard plastic coated
Operation:
Drilling
Correction factor for vf:
Veneered = 0.8
Paper coated = 0.8
