In the demanding landscape of modern CNC machining, achieving the perfect balance between speed and precision is a constant challenge. Ningbo Lianchuang Hewo Precision Tools Co., Ltd is at the forefront of this evolution, offering industrial-grade Solid Carbide Twist Drills engineered for high-intensity scenarios. Our tools are designed to redefine efficiency in the automotive and IT industries.
Our drills utilize high-quality YL10.2 sub-micro grain substrates combined with advanced TiAlN coating technology. This synergy results in an exceptional surface hardness exceeding HV2200 and a friction coefficient of ≤0.45. Featuring a precise point angle of 140°-148° and a 30° helix angle, these High-Performance Drills ensure stable Centering Performance even under high-stress conditions.
For critical components like automotive crankshaft oil holes, precision is non-negotiable. Ningbo Lianchuang Hewo Precision Tools Co., Ltd leverages a dual-spiral internal cooling structure and optimized variable helix flutes to maximize chip evacuation efficiency. This technology allows our tools to achieve IT9-IT11 diameter precision consistently on CNC machines.
According to 2024 utility model patent data, our latest two-stage web structure significantly boosts processing efficiency under Minimum Quantity Lubrication (MQL) conditions. This innovation allows a single cutting edge to exceed a lifespan of 450 holes, drastically lowering the cost-per-hole for our clients.
Trust Ningbo Lianchuang Hewo Precision Tools Co., Ltd to provide the Super Performance Tools your production line deserves.
