Tool holders with DirectCooling system (DC)
Accurate rather than spurted on: a new dimension of cooling tool cutting edges
When it comes to cooling lubrication, a little more may be required - but certainly not aimlessly and uncontrollably, because the efficient use of resources and sustainability make simple flood lubrication a thing of the past. The DirectCooling (DC) range from CERATIZIT offers accurate and targeted cooling rather than flood lubrication of the general area - and in doing so delivers the ultimate in precision.
How does DirectCooling (DC) work?
Tool holders with DirectCooling (DC) are equipped with two inner holes that guide the coolant to where it has the greatest impact: directly on the cutting edge. One hole targets the rake face from above and the other the flank from below. Why is this so important?
The precision flank cooling of the DirectCooling tool holder makes the difference: it extends tool lives by up to 63% compared to cooling that is targeted exclusively at the rake face.

Advantages of the MaxiLock-S-DC turning tool holder
Test report: Longitudinal turning of 1.4301
Indexable insert: CCMT 120408EN-M55 CTPM125
Material: 1.4301 – X5CrNi18-10
Cutting data: vc 200 m/min | f 0.25 mm/U | ap 2 mm
Result: With the DirectCooling cooling system, the tool life can be increased by 63% compared with a conventional cooling situation.
What's interesting here is that the lower coolant hole on the flank of the indexable insert has a considerable influence on the tool life. While cooling exclusively through the upper two nozzles gives rise to an improvement of just 22%, flank cooling achieves an increase of 63% compared with standard cooling!
