PVD Coated Double-End Grooving Insert 4mm Width R0.4 Neutral for CNC Lathe External Circlip Grooving

Product Overview

LCMF041604-M T8330 is a double-ended neutral deep grooving & parting insert of Pramet LCMF series, specially developed for 4mm wide slot processing with maximum 16mm deep cutting capacity. Equipped with M-type medium universal chipbreaker and smooth R0.4 corner radius, two independent usable cutting ends greatly reduce tool consumption cost. Adopting T8330 anti-wear PVD coating substrate, it perfectly matches LCMR16 and XLCCN modular grooving tool holders, supports deep external grooving, circlip slot turning and full shaft parting-off. Widely applied on CNC lathes and automatic lathes for automotive, hydraulic, mold and general machinery mass metal grooving production.

Key Features

• Double-ended symmetrical neutral structure, two complete cutting edges, bidirectional compatible with left/right hand tool holders, higher cost efficiency
• 4mm standard uniform cutting width, stable dimensional tolerance for circlip assembly grooves and uniform outer slots
• Max 16mm deep cutting design, solves deep groove processing demand inaccessible to short standard grooving inserts
• M optimized medium chipbreaker geometry, splits long steel chips into short curled fragments, effectively avoid chip winding and workpiece surface scratch
• T8330 smooth AlTiN PVD coating, low friction coefficient, significantly suppress built-up edge during steel continuous grooving
• Ultra-fine grain carbide substrate, strong edge toughness, anti-micro chipping under slight interrupted casting blank grooving
• Standard positioning lock structure, firm clamping on LCMR series tool holders, low vibration during deep depth heavy cutting
• Multi-process compatibility, covers external straight grooving, circlip slot machining and complete shaft parting-off operations
