​CNMG 432-PF
a_p = .012 – .059 inch
f_n = .004 – .016 inch/rev

Good chip control, primarily in steel.
Feed: .004 - .016 inch/rev. Depth of cut: .012 – .059 inch.
Operations: longitudinal turning, facing, back-turning and profiling
Components: typically axles, gears where good surface finish is a priority.
Advantages: light cutting geometry, low cutting forces suitable for slender shafts, thin-walled and unstably clamped components.
Limitations: depth of cut and feed range.
General recommendations: Combine with a more wear-resistant grade (ex.
GC4215) for best productivity; consider a cermet grade when surface finish
demands are very high with limited cutting speed.
Possible optimization: wiper geometry WMX and cermet grades.

CNMG 432-MF
a_p = .004 – .059 inch
f_n = .004 – .016 inch/rev​

Good chip control, primarily in stainless steel.
Feed: .002 – .020 inch/rev. Depth of cut: .004 – .150 inch.
Operations: finishing operations in general.
Components: stainless steel components in general.

General recommendations: especially suitable for external operations with high surface quality demands (suface finish values and visual finish).
Possible optimization: -R/L K (knife-edge geometry) and wiper geometry WL.

CNMG 432-QF
a_p = .008 – .098 inch
f_n = .004 – .014 inch/rev

Components: generally within mixed machining of steel.
Advantages: sharp, light cutting geometry generates low cutting forces with
possibilities for machining slender shafts, thin-wall components, and unstably
clamped components.

General recommendations: alternate to geometry PF when optimizing chip
breaking in very light finishing. Consider cermet grade for high surface finish
demands and when cutting speed is limited.

Operations: longitudinal turning, facing and profiling.
Components: generally components in steel and stainless steel.
Advantages: broad capabilities, suitable for semi-finishing and finishing with good chip breaking at lower area, alternate for gummy materials.
Limitations: depth of cut and feed combination (lower than geometry PF).
General recommendations: alternative solution to geometries PF and MF throughout the lower area.
Possible optimization: geometries PF, MF and WF.

CNMG 432-LC
a_p = .008 – .059 inch

Operations: longitudinal turning, profiling and facing.
Components: production of components in low carbon materials.
Advantages: reduced risk of chip jamming during machining, resulting in more production and less down time.
Limitations: depth of cut.
General recommendations: GC4215 for secure and reliable production in the steel area; GC1525 for good surface finish where there are limitations on speed; GC2025 for sticky materials with high toughness demands.

Feed: .0008 – .010 inch/rev. Depth of cut: .002 – .051 inch.
Operations: longitudinal turning, facing and profiling.
Components: generally in HRSA and stainless steel.
Advantages: positive, light cutting geometry generates low cutting forces for machining slender shafts, thin-walled components and unstably clamped components. Ground clearance face provides sharper cutting edge.
Limitations: depth of cut, feed rates and chip control
General recommendations: GC1105 for secure and reliable production, or combine with the more wear-resistant grade S05F for best productivity.
