WB 322-0


Workpiece material:
Chipboard with coating

Operation:
Boring

Correction factor for vf:
Veneered = 0,8
Paper coated = 0,8
MDF = 0,7

Drilling
Application example of Z 3 + V 3-design: Boring depth up to 13 mm depth in 16 mm thick workpieces. Because of the special centre-point no marks in the bottom surface layer.

Drill HW

Drilling

Design Z3/V3, GL = 57 mm. For high feeds compared to Z2/V2. Design without projecting centre-point. For boring workpieces near the bottom surface layer without marking or piercing the surface. Not suitable for solid wood.
