1. Product Overview

Designed for precision manufacturing, the WNMG080408PP CA525 combines advanced substrate technology with a multi-layer CVD coating. This insert is optimized for precision semi-finishing of carbon and alloy steels, delivering consistent performance across high-volume production runs.

With an inscribed circle of 8 mm, thickness of 3.97 mm, and a 0.8 mm nose radius, this insert is dimensionally optimized for precision semi-finishing. The Precision Finishing chipbreaker geometry ensures excellent chip evacuation and minimizes built-up edge formation.

6. Chipbreaker Profile

The PP chipbreaker offers a balanced geometry for precision semi-finishing. The moderate groove width and land width provide reliable chip control across a range of feeds and depths. It delivers consistent surface quality (Ra 0.8–1.6 µm) and is versatile enough for both continuous and lightly interrupted cuts in carbon and alloy steels.

Chipbreaker	Rake Angle	Groove Depth	Land Width	Best Feed Range	Best ap Range
HQ	+15°	0.10 mm	0.15 mm	0.05 – 0.15 mm/rev	0.1 – 0.8 mm

7. Recommended Applications & Workpiece Materials

The CA525 grade with WNMG080408PP geometry is recommended for the following workpiece materials and conditions:

Material Group	Examples	Hardness	Machinability	Recommended
P1.1 – P1.3	C15E, C35E, 1010, 1020	< 180 HB	★★★★★	Excellent
P2.1 – P2.5	C45E, 1045, 4140, 4340	180 – 280 HB	★★★★☆	Excellent
P3.1 – P3.3	50CrMo4, 34CrNiMo6, 300M	280 – 350 HB	★★★☆☆	Good
P4.1 – P4.2	Cast steels, GS-25	< 300 HB	★★★☆☆	Good
P5.1 – P5.2	Tool steels, H13, D2	Annealed	★★★☆☆	Good

8. Application Map by Operation

Chamfering	All Steels	Continuous	1.0 – 2.0 µm

9. Recommended Cutting Conditions

The following parameters are recommended for the WNMG080408PP CA525 insert. Adjustments may be needed based on machine rigidity, workpiece condition, and coolant application.

Parameter	Symbol	Minimum	Recommended	Maximum
Cutting Speed	Vc	180 m/min	250 m/min	320 m/min
Feed per Revolution	fn	0.05 mm/rev	0.12 mm/rev	0.2 mm/rev
Depth of Cut	ap	0.1 mm	0.8 mm	1.5 mm
Coolant Pressure	—	5 bar	15 bar	70 bar
Coolant Type	—	Emulsion (5%)	Emulsion (8–10%)	Synthetic / Neat Oil

10. Operating Guidelines

Tool Overhang: Minimize tool overhang to maintain rigidity. For internal boring, use the shortest possible holder and dampened bars if L/D > 4.
Edge Preparation: This insert features a precision-honed edge. Do not re-hone or alter the edge geometry, as this will compromise coating integrity.
Coolant Strategy: Apply high-pressure coolant directed at the cutting zone. For best results, use through-tool coolant delivery at 15–70 bar.
Workpiece Preparation: Ensure consistent stock allowance. Avoid scale, hard spots, or casting skin that can cause premature edge chipping.
Entry/Exit Strategy: Use ramp entry or arc-in programming to avoid full-width engagement on entry. Reduce feed by 30% during exit to prevent burr formation.
Tool Life Monitoring: Monitor flank wear (VB). Recommended tool-life criterion is VB = 0.15 mm for finishing and VB = 0.25 mm for general turning.
Storage: Store inserts in original packaging away from moisture and direct sunlight. Avoid contact between inserts to prevent edge damage.

11. Toolholder Compatibility

The WNMG080408PP insert is compatible with the following standard toolholders. Always verify holder seat angle and clamp type match the insert designation.

Toolholder Designation	Approach Angle	Application	Insert Size
MWLNR/L	95°	external	8 mm
