Heavy-Duty Grooving & Parting-Off Kit: KGHER 1.25" x 1.25" with 10 MGMN150 Inserts
Complete Solution for Reliable, High-Power Parting and Grooving
Engineered for maximum stability in demanding applications, this robust KGHER kit is built to handle aggressive feed rates and deep grooving with exceptional rigidity. The square shank design provides superior resistance to twisting forces, making it the perfect choice for wide-parting off, face grooving, and heavy-duty OD grooving on lathes and CNC turning centers.
Kit Includes:
1x KGHER Style Parting & Grooving Toolholder
Shank Dimensions: 1.25" x 1.25" Square – Maximum Rigidity & Torque Resistance
Style: KGHER (Right-Hand, External Parting/Grooving)
Clamp System: Top-Lock Screw Clamp for Secure Insert Seating
Material: High-Grade Alloy Steel, Heat-Treated and Precision Ground
10x MGMN150-Style Carbide Inserts
Size: MGMN150 (Ideal balance of strength and chip flow for 1.25" tools)
Grade: Premium Uncoated Carbide for General Purpose Use. (Coated options like AlTiN available for hardened/tough materials)
Geometry: Optimized chipbreaker for controlled, split-chip formation in parting.
Double-Sided: 2 cutting edges per insert for excellent value and extended tool life.
Key Features & Benefits:
Unmatched Stability: The massive 1.25" square shank virtually eliminates deflection and vibration, the #1 cause of failure in parting operations.
Built for Deep & Wide Cutting: Designed to part off larger diameters and cut wide grooves with confidence.
Superior Chip Control: The KGHER geometry and insert chipbreaker work together to create tight, "9"-shaped chips that evacuate safely, preventing clogging.
Cost-Effective Power: 10 inserts = 20 cutting edges. Reduce tooling costs and machine downtime.
Quick & Easy Setup: Pre-matched holder and inserts get you from box to production in minutes.
