Unique cooling booster

Chip evacuation and temperature control are challenges when machining titanium alloys. To overcome this challenge, select a CoroMill® Plura with internal coolant and a patent pending cooling booster for optimal control of chip evacuation and temperature.

Solid end mills
  • Optimized grades for all materials and conditions
  • Cylindrical, Weldon, and iLock™ shank options
  • Straight, conical with and without chip-dividing cutting edge tool shapes
  • With and without neck, undersized shanks available
  • PCD-tipped end mills with internal coolant
  • Can be reconditioned up to three times to its original specifications
Thread milling cutters
  • Four grades optimized for different ISO material groups
  • Two different designs available depending on the application, one with few cutting edges, and one multi-point design
  • Cylindrical and Weldon shank options
  • Individual radius programming (RPRG) value marked on the shank, giving the exact pitch diameter and radius correction required for optimum thread quality

​Application

CoroMill® Plura has a large assortment for heavy roughing to finishing and super-finishing.

Slotting
  • Heavy duty end mills with an extremely tough grade and optimized flute shape for effective chip evacuation offer full slot milling up to two times the diameter
Shoulder milling
  • End mills with an unequal helix angle for stability and excellent surface finish in high-feed side milling operations
  • Heavy duty end mills for shoulder milling with large engagements
Profiling
  • Wide range of ball nose end mills for all materials, including small cutter diameters down to 0.1 mm (0.004 inch), suitable for die and mold manufacturing where high precision is important
Chamfering
  • Tools for 45 and 60 degree chamfers and convex workpiece radius chamfers


High-Feed Side (HFS) milling

  • Designed for utilization of the complete cutting length to allow for higher Q value (MRR) with smaller diameters compared to traditional milling strategies.
    * Optimized for longer axial depth of cut, up to four times the tool diameter.
Thread milling
  • For both right- and left-handed internal threads
  • Up to 3 × diameter
  • The threads are milled in one or more passes, and the multi-point tool gives a true, full profile, 60 degree metric thread form. -M, -MJ, -UNC, -UNF, -NPT, -NPTF, and -G are available as options

Thread form​ Range​
-MM1.6 to M28​
-MJMJ4 to MJ12
-UNCNo. 1–64 to 3/4–10​
-UNFNo. 2–64 to 3/4–16​
-NPT1/8–27 to 1/2–14​
-NPTF1/8–27 to 1/2–14​
-GG1/8 to G1"–3"​

The performance of a grade depends highly on the geometry with which they are used. This graph provides a general picture of available graphs, but does not take geometries into consideration. Read the numbers in the graph like this:

XX00 – Super hard

XX10 – Hard grade for stable conditions and small ae

XX20 – Complementary grade to XX30 for all-around conditions with high feed rates

XX30 – Grade for all-around conditions

XX40 – Tough grade for unstable conditions and large ae

H10F – Uncoated grade for all-around conditions

N20C – Niche grade (diamond-coated)
