Product Short Description

Engineered for precision deep-hole machining, the CSJ Crown Drill Bit (10D, Ø18.00–18.99 mm) features a front-locking body with internal cooling and an indexable side-locking drill tip. Built for exceptional rigidity and efficient chip evacuation, it delivers high-speed, stable performance in continuous heavy-duty drilling operations.

Product Introduction

The CSJ 10D Crown Drill Bit delivers an advanced hole-making solution designed to handle challenging deep-hole applications up to 10 times its diameter. Featuring an innovative front-locking clamping structure and internal coolant channels, it allows quick head replacements directly on the machine while ensuring effective cooling and chip removal at the cutting zone. The replaceable indexable drill tip maximizes tool life, minimizes setup downtime, and lowers overall tooling costs for high-efficiency production environments.

Key Features & Functions

10D Deep-Hole Capability: Delivers straight, precise holes up to 10x diameter without requiring frequent peck-drilling cycles.
Internal Coolant Flow: Directs high-pressure fluid straight to the cutting edge, lowering heat generation and flushing chips out smoothly.
Front-Locking Design: Enables fast, rigid tip indexing directly on the machine spindle to reduce idle machine downtime.
Cost-Efficient Indexability: Allows single-tip replacement without discarding the main holder body, reducing overall tooling expenses.
High Structural Rigidity: Resists deflection under heavy torque to maintain bore accuracy, surface finish, and tool stability.

Application Scenarios

Automotive Manufacturing: Deep-hole drilling for engine blocks, crankshaft oil channels, transmission housings, and drive shafts.
Heavy Machinery & Equipment: Machining hydraulic cylinder bodies, structural plates, and heavy equipment frames.
Mould & Die Industry: Precision drilling for deep cooling lines, core pin holes, and ejector pin channels in injection molds.
General Engineering: Processing alloy steel, stainless steel, cast iron, and carbon steel components in high-volume CNC production runs.
