CoroMill® Plura HD - Solid end mills for heavy-duty milling

[@shirothehero0609]

Seeing waterfalls of steel chips change color in flight never gets old.

[@Convolutedtubules]

Even after years in the industry.

Both the tools and the videos are getting better and better! Keep improving, please👍

[@b2dmastersniper]

The shot at 1:12 is absolutely spectacular.

[@machiningmaniacs4131]

Great stuff !

[@Runkpapper]

Does the tool perform better with air-blast than flow coolant? Or is it just for filming? How long tool life you got with this feeds and speeds? Love the slo-mo btw

[@Convolutedtubules]

Flood or mist coolant are always best.

[@Stasiek_Zabojca]

@@Convolutedtubules Not always, especially not in ISO P steels. Cold coolant may cause thermal schock in carbide tools, which causes micro cracks and premature tool failrue. There is a reason why some manufacturers have two cutting speeds for face mills in their catalogues; dry and wet, which is always lower.

@@Stasiek_Zabojca You are right, thank you.

[@sandvikcoromant]

@@Stasiek_Zabojca @DailyToker As a rule of thumb we should strive away from using coolant in all intermittent cutting such as milling. Coolant increases the temperature difference between when being in cut and out of cut. This leads to accelerated thermal cracking and shortened tool life. Internal air can be a great substitute to coolant in terms of chip evacuation and keeping hydraulic chucks within allowed operating temperatures.Some materials requires coolant, also in milling applications. In those cases a material specific grade made to run wet should be selected. Like in this case Plura-HD grade: M2CM with internal coolant channels and optimized grade

But i wonder how expensive they are?

[@kisspeteristvan]

12mm diameter cutter 5 flute , list price in europe 215€ +tax . if you buy in bulk and have a good deal , i guess you can half the price ?

insane

Muito bom!

[@gulch1969]

Please stop with the slo-mo stuff. It's not impressive at all. We get it, end mills make chips fly. I want to actually HEAR the tool cut.

[@sandvikcoromant]

Hi there In the film you have plenty of sequences where you can hear the tool cut since we know that is important. The slow motion sequences we have are there to show the tool engagement more in detail, also you can see the chip formation. This is an appreciated part of these demo films since it show the performance of the tool in a visual way. Hope you will enjoy our films.

[@thedutchgamerguy8580]

I like the slomo's, good idea how its cutting

[@gulch1969]

@@sandvikcoromant I do enjoy your films, and am a regular buyer of a lot of your tooling. I especially love the Duramill end mills. Have never tried the Plura though.

[@buckwheatclark]

Don't listen to @gulch1969, he only uses HSS.

[@AdityaMehendale]

Both are present in the video - the SloMo gives an idea of the evenness and discoloration of the chips (which is equally indicative of the quality of the cutter). PS - @Sandvik GJ for changing the name to the known and trusted "Sandvik" instead of "Alliema" or whatever.
