Product Introduction

Product Summary
SHANDONG OLI MACHINERY CO., LTD introduces high-performance Eccentric Sleeves, designed to enhance precision and flexibility in drilling applications. These sleeves are engineered for use with U drills, quick drills, and water jet drills, offering adjustable tool diameters to meet diverse machining needs. Crafted from high-carbon steel, they ensure durability and long service life, making them a reliable choice for industrial tooling. With a processing range of -0.2mm to +0.4mm, these eccentric sleeves provide exceptional control over hole diameter adjustments, catering to both fine-tuning and broader machining requirements.

Basic Product Information

  • Product Name: Eccentric Sleeves
  • Material: High-carbon steel (ASTM A29 standard)
  • Application: Drilling operations, including U drills, quick drills, and water jet drills
  • Processing Range-0.2mm to +0.4mm
  • Adjustment Mechanism: Rotate the sleeve clockwise to increase hole diameter or counterclockwise to reduce it
  • Alignment Precision: Overlaps the shaft direction of the drill bit with the spindle within ±0.2mm

Product Features

Precision Diameter Adjustment
Eccentric sleeves allow for precise control over hole diameters, enabling operators to achieve the exact specifications required for their projects. By rotating the sleeve clockwise, the hole diameter increases, while a counterclockwise rotation reduces it. This adjustability ensures compatibility with a wide range of drilling tasks, from fine-tuning to broader adjustments.

High-Quality Material for Longevity
Manufactured from high-carbon steel, these sleeves are built to withstand the rigors of industrial drilling operations. The material’s inherent strength and wear resistance contribute to a long service life, reducing the need for frequent replacements and lowering operational costs.

Seamless Alignment with Spindle
The eccentric sleeve ensures the drill bit’s shaft direction aligns seamlessly with the spindle, maintaining precision within a ±0.2mm range. This feature minimizes deviations during drilling, enhancing accuracy and reducing the risk of errors in machining processes.

Versatile Application Across Drilling Tools
Designed for use with U drills, quick drills, and water jet drills, these sleeves are versatile tools that adapt to various drilling needs. Their adjustable nature makes them suitable for both standard and specialized drilling operations, offering flexibility in industrial settings.
