CSJ Crown Drill Bit, 5D Drill Diameter Range 29.00-29.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

CSJ Crown Drill Bit (5D, Ø29.00-29.99mm)

High-Speed Indexable Deep-Hole Drilling Solution

Product Short Description

The CSJ Crown Drill Bit is a high-performance, 5D indexable insert drill engineered for high-speed, deep-hole drilling applications. Featuring a precise front-locking body design and integrated internal cooling channels, this side-locking drill tip system ensures maximum stability, optimal chip evacuation, and superior hole quality across a diameter range of 29.00mm to 29.99mm.

Product Introduction

Designed for demanding industrial machining, the CSJ Crown Drill Bit redefines efficiency in deep-hole processing. With its 5D drilling depth capacity and an adjustable/selectable diameter range of 29.00mm to 29.99mm, this tooling system utilizes an advanced indexable/side-locking crown insert design.

The innovative front-locking body secures the drill tip firmly, minimizing runout and vibration even at high cutting speeds. Combined with an advanced internal cooling system that delivers coolant directly to the cutting edge, it significantly extends tool life and maintains thermal stability during continuous operations.

Product Key Parameters

Product Functions & Benefits

• High-Speed Deep Drilling: Easily achieves 5D depth ratios at elevated feeds and speeds without sacrificing accuracy.

• Rigid Front-Locking Mechanism: The secure side-locking tip and front-locking body prevent insert displacement under high torque, ensuring excellent hole straightness.

• Advanced Internal Cooling: Dual or center internal coolant holes flush chips out effortlessly from deep cavities, preventing tool jamming and reducing heat buildup.

• Cost-Efficient Indexable Design: No need to regrind the whole drill; simply index or replace the crown tip to maintain a brand-new cutting edge, minimizing downtime.

Application Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty manufacturing sectors, including:

• Heavy Machinery & Automotive: Drilling engine blocks, crankshafts, and heavy-duty transmission components.

• Aerospace & Energy: Processing tough alloys for turbine parts, wind power flanges, and structural components.

• Mold & Die Industries: Deep ejector pin holes and water cooling line drilling in large mold bases.

• Compatible Materials: Excellent performance in Carbon Steels, Alloy Steels, Cast Iron, and Stainless Steels.
