Material & Coating

Base Substrate: Premium hard alloy (cemented carbide) with tungsten carbide (WC) as the main component (92–94% by weight) and 6–8% cobalt (Co) as a binder. The ultra-fine WC grain size (1.0–1.5μm) ensures high density, delivering a hardness of 90–93 HRA—far superior to HSS (high-speed steel) in wear resistance, making it suitable for long-term high-intensity drilling.
PVD Coating: Adopts TiAlN (Titanium Aluminum Nitride) or TiCN (Titanium Carbonitride) PVD coating. The 3–5μm thick coating has a low friction coefficient (≤0.4), resists oxidation at temperatures up to 800°C, and blocks chemical corrosion from coolants. This extends the insert’s wear resistance by 30–50% compared to uncoated inserts.

Key Product Features

Precise U Drill Compatibility: Custom-engineered for SP series U drills (2D, 3D, 4D, 5D—“D” refers to the ratio of drill depth to diameter). The insert’s seating surface is ground to ±0.002mm tolerance, ensuring a tight fit with U drill holders, minimizing runout (≤0.003mm) and guaranteeing consistent hole accuracy (IT8–IT9 tolerance).
Grade-Specific Hardness for Versatility: Offered in three hardness grades to match different materials:

P15–P25: For carbon steel, alloy steel, and gray cast iron—ideal for general-purpose drilling (e.g., automotive engine block bolt holes).
M10–M25: For stainless steel (304/316) and heat-resistant alloys—prevents work hardening and built-up edge (BUE) during drilling.
K10–K25: For ductile cast iron and non-ferrous metals (aluminum 6061, brass)—balances toughness and wear resistance to avoid chipping.

Efficient Chip Control: Integrated curved chipbreaker grooves are designed to split swarf into short, manageable pieces. This prevents clogging in deep holes (up to 5x diameter) and reduces heat accumulation, protecting the insert edge from premature wear.
High-Speed Drilling Capability: The rigid alloy and low-friction coating enable 2–3x faster drilling speeds than HSS: 150–300 m/min for steel, 80–150 m/min for stainless steel, and 300–600 m/min for aluminum—cutting cycle time by 40%.

Lifespan & Maintenance

Service Life:

Steel drilling: 500–1,000 holes (e.g., M10 holes in 45# steel).
Aluminum drilling: 800–1,500 holes (lower material abrasiveness extends life).
Stainless steel drilling: 300–600 holes (high wear due to material toughness).

Maintenance Tips:

Clean the insert and holder with compressed air after use to remove swarf and coolant residue.
Store in a dry, dust-free case to avoid coating corrosion.
Avoid dropping or impact (may chip the hard alloy edge, reducing precision).
