1x KGHER Style Heavy-Duty Toolholder
Shank: 1.25 x 1.25 Inch Square – Provides maximum resistance to twisting and vibration.
Style: KGHER (Right-Hand, External Parting & Grooving)
Clamp: Top-Lock Screw with Integrated Anvil for rock-solid insert seating.
Construction: Premium alloy steel, hardened and precision ground.
10x MGMN200-Style Carbide Inserts
Size: MGMN400 – Larger cutting edge for superior strength and heat management.
Grade: High-performance uncoated carbide (Standard). Coated grades available for hardened materials and high-temperature alloys.
Chipbreaker: Optimized for controlled chip formation in parting and grooving.
Edges: 2 double-sided edges per insert (20 total edges).
Key Features & Benefits:
Eliminates Vibration: The massive square shank design ensures stability, preventing tool failure and poor surface finish.
Built for Heavy Cuts: Ideal for parting larger diameters, wide grooves, and aggressive feed rates where tool strength is non-negotiable.
Superior Chip Control: Geometry promotes tightly coiled, broken chips that evacuate safely from deep grooves.
Extended Tool Life: The larger MGMN300 insert provides more support behind the cutting edge, reducing chipping and wear.
Complete Ready-to-Run Kit: Get maximum uptime with a perfectly matched holder and a full set of inserts.
