Quantity: 1 x

The packaging unit defines the number of articles in one package:

For example:
1x gloves: 1 pair (2 pieces)
1x bit set: 1 set (10 pieces)
1x screw: package (50 pieces)

In many areas our 8 - digit article number is structured the following way:

First 5 digits = material no . / Product no . + last 3 digits = dimensions / diameter / article no.

For example, solid carbide end mills 3x5x50mm first 5 digits 16851 + last 3 points 050

article no.: 16851050

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units

The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.

In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart.
