Application area

The ideal tool for machining sheet metal.

Centring, tapping, drilling and deburring of metal sheets, pipes and profiles in a single work process.

Ideal for use in the electrical trade, sanitation and heating systems, automotive workshops, mechanical engineering, switch cabinet construction, and container and equipment engineering.

Ideal for use in cordless drivers as well as on hand, box column and pillar drills.

For unalloyed and alloyed steels, cast materials, aluminium, non-ferrous metals, wood and plastics with a material thickness of up to 3.5 mm.

Instructions

Ensure that there is sufficient coolant/lubricant.

Observe the speed table.

Do not push during hole enlarging. The stepped drill bit automatically draws itself into the sheet metal.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with v

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
