3D 4D Indexable Insert Drill Widely Used 10mm Diameter High Durability

The U Drill, also known as an indexable insert drill, is a high-performance drilling tool widely used in modern CNC machining. It is designed for fast, efficient, and economical drilling of through and blind holes, typically in the diameter range of 10 mm and above.

Unlike traditional solid drills, the U Drill features replaceable carbide inserts mounted on a rigid steel body. This allows for easy maintenance, cost-effective operation, and high productivity, especially in mass production environments.

Features:

Indexable Insert Design: Replaceable inserts eliminate the need for regrinding and reduce tool change time.

Internal Coolant Channels: Coolant flows through the drill body directly to the cutting edge, improving chip evacuation and tool life.

Various Lengths Available: Offered in 2×D, 3×D, 4×D, and 5×D effective drilling depths.

High Rigidity: Robust body construction ensures stability during high-speed or heavy-duty machining.

Wide Material Compatibility: Suitable for machining steel, stainless steel, cast iron, aluminum alloys, and more.

Technical Parameters:

Applications:

Applications:

• High-speed drilling in CNC lathes and machining centers
• Pre-machining for boring, reaming, or tapping
• Rough boring of large-diameter holes
• Mass production and automated environments
