Product Description:
U Drill , also referred to as an Indexable Insert Drill or Insert-Type Drill , is a cutting-edge drilling tool specifically engineered to optimize hole-making processes in contemporary CNC machining settings. This innovative tool seamlessly integrates the durability of a solid body with the adaptability of replaceable carbide inserts, providing a winning combination of productivity and cost-effectiveness.
Features:
Features:
Indexable Inserts: Equipped with two or more replaceable carbide inserts, which eliminate the need for regrinding and reduce tool change time.
Multiple Length Options: Available in standard drilling depths such as 2×D, 3×D, 4×D, and 5×D.
Internal Coolant Channels: Provides through-tool coolant delivery for effective chip evacuation and improved tool life.
High Rigidity: The robust shank design ensures high rigidity and vibration resistance, suitable for high-speed machining.
Cost-Effective: Only the inserts need to be replaced, significantly lowering tooling costs over time.
Versatile Material Application: Suitable for machining steel, stainless steel, cast iron, aluminum alloys, and exotic materials.
