CSJ Crown Drill Bit,10D Drill Diameter Range 34.00-34.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

High-performance 10D CSJ Crown Drill Bit featuring a front-locking design, internal cooling system, and indexable/side-locking drill tip structure. Engineered for high-speed, high-precision deep-hole drilling across a 34.00 mm – 34.99 mm diameter range. Ideal for heavy-duty metalworking and production environments.

Product Introduction

The CSJ Crown Drill Bit (10D Series) is an advanced deep-hole drilling solution designed to meet the rigorous demands of modern high-speed CNC machining. Built with a robust front-locking body mechanism and dual internal cooling channels, this indexable side-locking drill bit delivers exceptional chip evacuation, reduced heat accumulation, and outstanding dimensional accuracy.

Engineered specifically for drilling depths up to 10 times the drill diameter (10D), the CSJ series accommodates drill diameters ranging from 34.00 mm to 34.99 mm. Its exchangeable crown/insert system maximizes productivity by enabling fast tool changes without removing the entire body from the machine spindle, significantly minimizing equipment downtime and lowering overall tooling cost per hole.

Product Key Functions & Features

1. High-Speed 10D Deep-Hole Capability: Designed to drill clean, straight holes up to 10D depth in a single pass without pecking, reducing cycle times substantially.

2. Front-Locking & Side-Locking Stability: The front-locking structural design combined with a side-locking tip mechanism ensures rigid clamping, low runout, and high repeated centering accuracy under heavy cutting forces.

3. Internal Cooling & Effective Chip Evacuation: Dual internal coolant channels flush cutting fluid directly to the cutting edge, rapidly lowering temperatures and pushing chips smoothy out of deep holes to prevent chip clogging and tool breakage.

4. Cost-Effective Indexable Design: Only the crown tip or insert needs replacement when worn, extending the life of the drill body and lowering long-term consumable expenses.
