6. Drilling

6.1 Dowel drills

No. of teeth: Z2/V2
RPM: n = 3000-12000 min-1

Drilling

Design without heel

Diagram to determine the feed speed vf depending on the RPM n of the spindle

Drilling

HW-Dowel boring bit Z2/V2
WB 120-0-32, WB 120-0-33

Workpiece material:
Chipboard with coating, abrasive wood, composits

Operation:
Boring

Correction factor for vf:
Veneered = 0,8
Paper coated = 0,8
MDF, solid wood = 0,7
Chipboard, without coating = 1,3

Shank 10 mm

Drilling

Boring bit designed for machining panels in the furniture industry. Minimal friction and feed forces as the flute has a smaller diameter. A loose countersink can be clamped on the shank WB 701-0-02.
