Specification

A Jack of all trades with extremely uneven pitch (EU) and TiAlN coating for perfect cuts and maximum performance.

Extremely uneven pitch

Maximum surface quality: exact, round, chatter-free countersinks

Faster processing thanks to higher cutting speeds

Greatly reduced tool wear

Maximum smoothness in all materials

Much less feed force required

3-face shank

No slippage, ideal for use in hand drills with 3-jaw chuck

Universal application

Processing of almost all materials possible thanks to special tip geometry and HSCo cutting material.

Long service life and high speed

due to super-hard coating based on titanium aluminium nitride

Sustainable product packaging made from 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified^_® in Bronze

CUT+COOL drilling and cutting oil

CUTOIL-DRILL-(CUT-COOL)-400ML

Art.-no. 0893050004

Multi cutting oil for light to medium machining work

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 Easy-/VarioScan. The packaging unit will be determined automatically.

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
04076

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, as well as in our General Terms and Conditions (GTC).
