Korloy VNMG160404-HA H01

“Upgrade your productivity: one insert that fights edge wear, boosts tool life, and slashes cost per part.”

• Geometry & Type: VNMG (35° diamond / rhombic) negative-type indexable insert. 

• Dimensions / Key geometry:
   - Cutting edge length (B1): ~ 16.6 mm 
   - Inscribed circle diameter (IC): 9.525 mm (equivalent to 3/8″) 
   - Thickness: 4.76 mm
   - Corner radius (rε): 0.4 mm 

• Chipbreaker / Face style: HA chipbreaker (dual-face chipbreaker) for medium and finishing operations.

• Grade / Substrate / Coating: Grade H01 (Korloy’s uncoated / polished ultra-fine carbide substrate) — often used for cast iron, nonferrous, and certain steels.

• Relief / Clearance Angle: It is a 0° major clearance (zero-relief) style for its negative insert type.

• Mounting / Hole: Bore with 3.81 mm fixing hole.

• Hand / Orientation: Neutral / standard orientation (not left/right).

• Longer Tool Life & Reduced Downtime — The ultra-fine substrate of the H01 grade resists edge degradation under finishing cuts, giving more parts per edge.

• Stable Chip Behavior & Surface Finish — The HA chipbreaker ensures predictable chip control and low cutting force, reducing chatter and enhancing surface quality.

• Lower Cost per Component — You replace inserts less frequently, reducing tool change interruptions and scrap.

• High Wear & Chipping Resistance — In finishing or semi finishes, the insert resists flank wear and edge chipping better than generic grades.

• Versatility in Machining — Because of neutral orientation and balanced geometry, it fits many standard turning holders and can serve across multiple part types.

These practical gains are why this model is widely stocked and requested by turning shops — it gives a dependable finishing insert with solid lifecycle characteristics.

• Automotive — precision shafting, housings, small engine components

• Aerospace / Defense — finishing of nonferrous or cast structural parts

• Die & Mold / Tooling — final passes on mold inserts, cores, cavities

• General Engineering & Fabrication — small to medium runs on steel, castings, nonferrous parts

• Pump / Valve / Hydraulic Components — where tight tolerances and good surface finish are needed

• Designed for turning / external turning applications (negative insert geometry).

• Suitable for finishing or light to medium semi-finishing passes (thanks to HA chipbreaker).

• Works well on cast iron, nonferrous materials, and certain steels (as per Korloy reference for H01 grade) 

• Because H01 is uncoated / polished, it is less ideal for highly abrasive or heavy interrupted steels — but in stable finishing cuts it offers low friction and consistent edge performance.
