Rear Pull Crown Drill U Drill High-Precision Deep Hole Drilling

The "Crown Drill" is an efficient and economical hole-making tool in CNC machining, technically known as an indexable insert drill or replaceable tip drill. It features a unique modular design that separates the tool holder from the replaceable cemented carbide drill tip (shaped like a crown). When the tip wears out, it can be directly replaced without the need for regrinding, minimizing machine downtime and ensuring consistent performance. This design significantly reduces long-term tooling costs and is particularly suitable for high-volume production lines requiring medium-precision hole machining
