CSJ Crown Drill Bit,10D Drill Diameter Range 27.00-27.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

CSJ Crown Drill Bit (10D, Ø27.00–27.99 mm)

Short Description

The CSJ Crown Drill Bit (10D) is a high-performance, indexable front-locking drill engineered for high-speed, deep-hole drilling applications. Designed to cover a diameter range of 27.00 mm to 27.99 mm, it combines internal cooling with a rigid side-locking tip structure to deliver maximum stability, efficient chip evacuation, and exceptional hole accuracy at 10x diameter depths.

Product Introduction

Built for demanding industrial machining, the CSJ Crown Drill Bit features an advanced front-locking body combined with a side-locking drill tip mechanism to ensure ultra-secure insert clamping under heavy torque. Its 10D depth capacity makes deep-hole drilling fast and reliable without sacrificing rigidity or tool life. Integrated internal coolant channels supply high-pressure fluid directly to the cutting edges, dramatically reducing thermal stress, optimizing chip clearance, and extending overall tool longevity during high-speed operations.

Product Specifications

Key Functions & Advantages

• High-Speed 10D Drilling: Executes deep holes up to 10 times the drill diameter in a single pass without deflection.

• Dual-Locking Stability: Combine front-locking body design with side-locking tip alignment to withstand heavy cutting forces and prevent insert displacement.

• Internal Cooling: Direct coolant delivery lubricates the cutting zone, cools the edge, and flushes chips out smoothly.

• Cost Efficiency: Replaceable indexable tips eliminate the need for resharpening, lowering tool setup costs and downtime.

Application Scenarios

• Heavy Equipment Manufacturing: Drilling deep structural holes in large castings, machinery frames, and forged components.

• Oil & Gas Industry: Machining valve bodies, manifolds, flanges, and high-pressure piping components.

• Automotive & Transportation: Heavy-duty vehicle power systems, drive axles, and engine block processing.

• Mold & Die Fabrication: Creating deep cooling channels and pin holes in large mold bases.

• General Precision Engineering: High-efficiency CNC lathe and machining center operations requiring deep, accurate hole processing.
