Kennametal DFT05T308HP KC7140 PVD Coated High Feed Indexable Insert with R0.8 Reinforced Corner for CNC Machining

Product Overview

DFT05T308HP KC7140 is an original high-feed indexable triangular drill insert under Kennametal Drill Fix DFT series, specially developed for high-efficiency shallow hole and medium-deep hole drilling. Equipped with HP high-feed chipbreaker and R0.8 reinforced cutting corner, matched with DFT series modular U-drill bodies, this insert adopts KC7140 premium PVD coated carbide substrate to balance hardness and toughness. It performs stably in continuous batch drilling of carbon steel, alloy steel, stainless steel and cast iron, effectively reducing cutting heat, avoiding edge chipping and solving chip winding problems in mass production. Widely used on vertical machining centers and mill-turn machines for mold, auto and hydraulic precision hole machining.

Key Features

• Exclusive HP high-feed chipbreaker design, lower cutting load, generates tiny broken chips for smooth evacuation
• Reinforced R0.8 edge radius, strong anti-chipping capacity, long service life under heavy feed rate
• KC7140 multi-layer TiAlN PVD coating, outstanding heat resistance and anti-adhesion for stainless steel processing
• Ultra-fine grain carbide base, high toughness to resist work hardening of stainless and heat-resistant alloys
• Standard triangular Drill Fix geometry, precise positioning on DFT drill bodies, high repeat accuracy after insert replacement
• Adaptable to 2D, 3D, 4D shallow hole drill lengths, covering most conventional hole depth machining demands
• Suitable for dry and coolant cooling conditions, compatible with high-pressure internal coolant drill systems
