CoroMill 327 and 328

CoroMill^Ž 327 and 328 grooving cutter

For use in internal machining of eccentric components e.g gearbox casings, high volume assembly, mainly on machining centres.

	A universal cutter for use in all materials PMKNS
	Sharp cutting edges for high quality grooves
	One grade; PVD coated GC1025 for all materials
	Multiple edges for high productive economic machining

Operations:
	Internal grooving
	Slot milling
	Threading

CoroMill 327 and CoroMill 328

CoroMill 327

-	Inserts for grooving/circlip, widths 0.7-5.15 mm.
-	Chamfer inserts, Dmin 12 and 22 mm.
-	Inserts for both circlip and chamfering in one operation, widths 1.1–4.15 mm.
-	Full radius inserts, widths 1–4 mm.
-	Internal circlip grooving, thread milling and slot milling applications
-	Comes in four different sizes of cutter with three and six effective cutting edges for high metal removal rate
-	Insert size 06 gives access for smaller holes and highest table feeds
-	The largest cutter size for unstable operations where longer tool lengths are required and where larger slot widths and depths of cut are required
-	Steel and carbide shank with different lengths giving stable set up and higher productivity
-	Weldon shanks available

CoroMill 328

-	Circlip grooving for holes over dia 39 mm
-	Inserts for both circlip and chamfering in one operation, widths 1.1–5.15 mm.
-	Comes in 4 tool holder sizes with only 1 insert size
-	Circlip inserts, widths 1.30-5.15 mm
-	Thread milling applications
-	2-8 inserts, each with three indexable cutting edges for high productivity and economy
-	With Weldon (B), arbor (Q) and bore with keyway mounting (S)

Thread milling
These tools are an excellent alternative for tapped holes.
- Lower power consumption
- Good chip control

Use

-	when difficult materials cause undesirable chip evacuation problems
-	when machining non rotating components
-	when machining up against a shoulder
-	when machining thin walled components
-	when you need a greater flexibility with diameter and pitch range

Threading inserts
Inserts for metric, UN and Whitworth threads for CM327.
Inserts for metric and UN for CM328.

	Tool holders
	Parting and grooving systems

These tools are an excellent alternative for tapped holes.

Application hint
For best performance always make sure to
- clean the tip seat before use
- preload the tip seat
- use the right torque for mounting the insert
