SA - Parting off

General information

The cost effective solution for radial grooving as well as parting off up to 5.512" (140mm) in diameter. The monoblock holder "SA" is being used with the double sided inserts SA16, SA17, SA24, SA35 und SA40 in .059" (1.5mm), .079" (2mm), .118" (3mm), .157" (4mm), .197" (5mm), .236" (6mm), .315 " (8mm) und .394" (10mm) widths.

Get to know the special ARNO-ACS cooling system® for SA - parting off.The Special coolant System ensures the flow is directed under the swarf and thereby improves tool life considerably. Through a second coolant jet additional coolant gets right on the tool flank.

AM5040 PVD coated carbide grade
Fine grain carbide + TIALN
A tough but universal grade for low to medium cutting speeds. The main
application area is stainless steel.

AP5020 PVD coated carbide grade
Fine grain carbide + TIALN
A universal grade for low to medium cutting speed. Main application areas are steel and stainless steel, but also suitable for parting off high temperature alloys and non ferrous materials.

AP2220 CVD coated carbide grade
Fine grain carbide + multilayer coating
Grade with excellent combination of wear resistance and cutting edge stability. Main application area are alloyed steel and cast materials, under stable conditions also suitable for stainless steel at medium to high cutting speeds.

AP5030 PVD coated carbide grade
Fine grain carbide + TIALN
A universal grade mainly for steel applications. The slightly tougher substrate (ISO P30-P35) makes it also suitable for stainless steel.



Uncoated caride grade which in Connection with a ground cutting edge is for finishing and roughing of Aluminium alloys and non-ferrous materials. In order to reduce build up edge Problems the insert is also highly polished.
