CSJ Crown Drill Bit,10D Drill Diameter Range 26.00-26.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

High-performance 10D indexable crown drill designed for deep-hole machining. Featuring a robust front-locking/side-locking mechanism and internal cooling channels, it delivers exceptional stability, superior chip evacuation, and high-speed precision drilling across tough materials.

Product Introduction

The CSJ Crown Drill Bit system is an advanced deep-hole drilling solution engineered for maximum efficiency and dimensional accuracy. Built for long-reach operations requiring a 10D depth-to-diameter ratio, it utilizes interchangeable crown tips in the range of 26.00 mm to 26.99 mm. The secure front-locking and side-locking mechanism ensures rigid insert clamping, minimizing vibration and radial runout during high-speed feed passes. Integrated internal coolant passages deliver high-pressure fluid directly to the cutting edge, rapidly lowering heat generation and flushing chips out of deep cavities smoothly to prevent tool breakage.

Product Functions

• Vibration Suppression: Secure locking design ensures high body rigidity, dramatically reducing tool deflection and chatter in deep-reach operations.

• Efficient Heat & Chip Management: Internal coolant channels cool the cutting zone instantly while propelling chips out through flutes without clogging.

• Cost-Effective Tooling: Quick-change crown inserts allow operators to replace worn tips without replacing the entire drill body or re-aligning offsets.

• Superior Surface Quality: Delivers clean entry, precise hole tolerance, and smooth wall finish even at extended depth ratios.

Applications & Target Industries

• Mold & Die Manufacturing: Ejector pin holes, deep water cooling channels, and core pin cavities.

• Heavy Machinery & Engineering: Transmission shafts, hydraulic manifolds, and structural flanges.

• Automotive Industry: Engine block oil passages, crankshaft oil holes, and powertrain components.

• Energy & Oil/Gas: Heat exchanger tube sheets, valve bodies, and flange bolt patterns.

• Suitable Materials: Alloy steels, stainless steels, cast iron, carbon steels, and high-temperature alloys.
