6.1 Dowel drills

Drilling
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, solid carbide

Drilling

Design Z2/V2 in solid tungsten carbide for extremely large regrinding area and increased feed speed, marathon design grind. Ideal for machining abrasive wood and composite materials as the solid tungsten carbide is more wear-resistant. Z3-design for higher feed speeds than Z2-design.

6.2 Through-hole drills

Drilling
No. of teeth: Z2
RPM: n = 3000-9000 min-1
n = 3000-12000 min-1
for solid tungsten carbide design

HW-Through-hole boring bit
WB 101-0-xx


Workpiece material:
Chipboard with coating

Operation:
Boring

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

Recommendation:
For diameters below 5 mm use type
WB 101-0-04 (page 586).

Shank 10 mm

Drilling

Optimised boring bit when there is insufficient spindle guide (by centering the boring bit during the exit stroke to prevent tear-outs at the edge of the hole when the boring bit leaves the workpiece) and for machining hard and softwood. A loose countersink can be clamped on the shank WB 701-0-03.
