CSJ Crown Drill Bit,10D Drill Diameter Range 12.00-12.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Product Description

The CSJ Crown Drill Bit is a high-performance 10D deep-hole drilling solution designed for drill diameters from 12.00 to 12.99 mm. Featuring a front-locking body, internal cooling, and indexable insert drill tip, it provides stable cutting performance, efficient chip evacuation, and reliable tool life in high-speed deep-hole drilling applications.

Product Introduction

The CSJ Crown Drill Bit is engineered for high-speed and deep-hole drilling where accuracy, rigidity, cooling efficiency, and consistent cutting performance are essential. With a 10D drilling depth capability, this drill is designed to achieve deep drilling without requiring frequent tool changes or specialized step-drilling operations.

The drill features a front-locking body design that securely positions the cutting tip while maintaining excellent stability during machining. The indexable insert system allows the cutting tip to be replaced when worn, helping reduce tooling costs and minimize machine downtime.

An integrated internal cooling system delivers coolant directly toward the cutting area. This improves heat control, assists with chip evacuation, and helps maintain stable cutting conditions during high-speed drilling. Internal coolant is particularly beneficial when drilling deep holes because chips and heat can become difficult to remove as drilling depth increases.

The CSJ Crown Drill Bit is suitable for CNC machining centers, automatic machining equipment, and other precision drilling systems. Its combination of replaceable cutting inserts, internal cooling, and rigid front-locking construction makes it suitable for demanding industrial production environments.

Product Function

The CSJ Crown Drill Bit is primarily used for high-speed drilling of deep, accurate holes in industrial machining operations. Its 10D configuration allows manufacturers to drill holes significantly deeper than conventional short drills while maintaining stable cutting conditions.

The internal cooling system helps deliver coolant close to the cutting zone, reducing cutting temperature and improving chip evacuation. This can help prevent excessive heat buildup and reduce the risk of chip accumulation inside deep holes.

The indexable insert design provides an economical solution for long-term production. Instead of replacing the entire drill when the cutting edge becomes worn, the insert can be replaced, helping reduce tooling costs and simplify maintenance.

The front-locking body provides secure insert positioning and contributes to cutting stability. This is especially important during deep-hole drilling, where vibration, deflection, and unstable cutting conditions can negatively affect hole quality.

Key Product Benefits

1. Designed for 10D Deep-Hole Drilling

The 10D design is optimized for drilling applications where the required hole depth can reach approximately ten times the drill diameter. It is suitable for deep-hole machining while maintaining efficient cutting and chip evacuation.

2. Wide Diameter Range

The CSJ Crown Drill Bit supports drill diameters from 12.00 to 12.99 mm, making it suitable for a variety of precision drilling requirements in industrial production.

3. Internal Cooling

Internal coolant delivery helps control cutting temperature and improve chip evacuation. This is particularly valuable when drilling deep holes at higher cutting speeds.

4. Replaceable Indexable Insert

The indexable insert cutting system allows worn cutting edges to be replaced without replacing the complete drill body. This can improve tooling economics and reduce machine downtime.

5. Stable Front-Locking Structure

The front-locking design helps maintain secure positioning of the cutting insert during machining, contributing to improved stability, repeatability, and hole quality.

6. Suitable for High-Speed Machining

The drill is designed for high-speed drilling operations where productivity and consistent cutting performance are important. Proper cutting parameters and coolant selection can further improve machining results.

Application Scenarios

CNC Machining

The CSJ Crown Drill Bit is suitable for CNC machining centers that require accurate and repeatable deep-hole drilling. It can be integrated into automated production processes where consistent hole quality and productivity are required.

Automotive Component Manufacturing

The drill can be used for machining automotive components that require precision holes, including various metal housings, mechanical components, shafts, brackets, and other parts.

Machinery Manufacturing

In general machinery production, the drill is suitable for creating deep mounting holes, connection holes, positioning holes, and other precision holes in metal components.

Mold and Die Manufacturing

Deep-hole drilling is frequently required in mold and die production. The internal cooling and replaceable insert design make the CSJ Crown Drill Bit suitable for demanding drilling operations where thermal control and tool stability are important.

Industrial Equipment Manufacturing

The drill can be applied to industrial equipment components that require accurate and repeatable deep holes, particularly when production efficiency and tool maintenance costs are important considerations.

High-Volume Production

The replaceable insert configuration makes this drill suitable for production environments where the same hole geometry must be machined repeatedly. Operators can replace worn inserts instead of replacing the complete drill body, helping reduce production interruptions.

Recommended Use

For optimal performance, the CSJ Crown Drill Bit should be used with a suitable CNC machine, stable workholding, appropriate cutting parameters, and sufficient coolant flow. Actual cutting speed, feed rate, coolant pressure, and insert selection should be adjusted according to the workpiece material, hole diameter, drilling depth, machine capability, and production requirements.

The CSJ Crown Drill Bit is an ideal choice for manufacturers looking for a replaceable-insert 10D deep-hole drilling solution with internal cooling and front-locking construction.
