Key Features & Specs
-
Geometry: VBMT 160404HQ – rhombic 35° insert, 9.525 mm inscribed circle, 4.76 mm thickness, 0.4 mm corner radius (rε = 0.4 mm) for fine finishing/medium operations.
-
Grade: CJ225P – Kyocera’s universal grade for steel/forging for finishing & medium operations, offering excellent toughness and wear resistance.
-
Coating / Substrate: Coated carbide (CVD/PVD depending on variant) built for stable machining and long tool life.
-
Cutting Applications: Optimised for turning operations (off-centre, finish to medium cuts) on steel, alloy steel, including forged components – excellent chip control even at low feeds and small depths of cut.
Why It’s a Best Seller:
Because in practical shop-floor terms it delivers:
-
Longer tool life – The CJ225P grade maintains its edge and resists wear even when machining tough steels.
-
Reduced downtime – With fewer insert changes and less edge failure, your machine runs longer between stops.
-
Better surface finish – The fine 0.4 mm corner radius and stable cutter geometry give cleaner part finishes, less secondary work.
-
Cost-per-component reduction – Longer life + less scrap + less rework = lower overall machining cost.
-
Chip control – Designed for light interruptions and small ap/fz operations where chip control tends to degrade – this insert handles it smoothly.

Frequently Asked Questions
The insert is optimised for steel and alloy steel work-pieces (including forgings) in finishing to medium turning operations. The CJ225P grade offers universal performance for steel machining.
It uses the VBMT 160404HQ geometry: rhombic 35° shape, inscribed circle approx 9.525 mm, thickness about 4.76 mm and a corner radius of approx 0.4 mm (rε = 0.4 mm) – ideal for good surface finish.
The CJ225P grade from Kyocera provides excellent wear resistance and toughness, enabling stable machining even in steel/forged applications. It helps reduce edge-fracture and extend insert life.
Industries such as automotive, aerospace, die & mold, general engineering all benefit – especially where steel/forged components are machined and surface finish, tool life and downtime are critical.
