Circlips on shaft and axle components are common for several mechanical applications. Different circlip widths are described in an ISO standard that determines the choice of insert width.
Choice of tools
For best cost efficiency, use the three edged U-Lock 154.0 system. The insert has sharp edges which produce high quality grooves.
The second choice is CoroCut 2-edge with -GF geometry. The insert offers low cutting forces and good surface finish due to sharp cutting edges.
Small circlip grooves
For small circlip grooves, use the three-edged CoroCut 3 with -GS geometry. The insert produces circlip grooves down to .020 inch.
Milling circlip grooves
For milling circlip grooves, the CoroMill 327 is the first choice for internal or small holes, and the CoroMill 328 is the first choice for external or large holes.
Tool holder recommendation
CoroCut 3 holder. Torx Plus key - screwdriver
The U-Lock 154.0 insert must be used with the U-Lock tool holder. The correct shim has to be used to produce a 0º inclination angle.
The U-Lock 154.0 insert could also be used with the Coromant Capto system.
The CoroCut 3 tool holder is available as right- and left-hand styles. Choose insert seat size to match holder and insert.
Coromant Capto and SL cutting head can also be used.
