Key Advantages:
High Efficiency: Typically 2-3 times faster than twist drills, with cutting speeds exceeding 80m/min
No Pilot Hole Required: Can drill directly into the workpiece without a center drill
Good Accuracy: Better hole tolerance and surface finish than twist drills; can sometimes replace rough boring
Cost-Effective: Indexable inserts allow quick changes while the drill body is reused
Typical Applications:
Diameter range typically from φ8.5mm to φ80mm, with common depth-to-diameter ratios of 2D-5D
Suitable for machining centers and CNC lathes, capable of drilling steel, cast iron, stainless steel, and other materials
