Product Description:
The U Drill
The U Drill, also referred to as an indexable insert drill, is a cutting-edge drilling tool essential in contemporary CNC machining operations. This high-performance tool is specifically crafted for swift, effective, and cost-efficient drilling of both through and blind holes, generally ranging in diameters of 10 mm and larger.
Unique Design
Setting it apart from conventional solid drills, the U Drill showcases replaceable carbide inserts affixed onto a sturdy steel body. This innovative design enables simple maintenance, economical operation, and enhanced productivity, particularly advantageous in high-volume production settings.
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.
