2.25in Concrete Core Drill Bit (Open-Head)

2.25in Concrete Core Drill Bit (Open-Head)

2.25in (57.2mm) Concrete Core Drill Bit (Open-Head)

The 2.25in Concrete Core Drill Bit (Open-Head) is a professional-grade tool designed for precise coring of hardened concrete or asphalt, ideal for laboratory testing and evaluation. It is compatible with both gasoline- and electric-powered core drilling machines and is perfect for use in construction, roadwork, and material analysis applications. This durable, high-performance bit is equipped for wet-use drilling, ensuring efficient operation through reinforced concrete and similarly tough materials. The bit’s diamond-tipped design guarantees fast cutting, durability, and suitability for heavy-duty, high-output environments. For long-term use, worn bits can be refurbished, extending their lifespan and cost-efficiency.

Compatibility and Setup:

The Open-Head Coring Bit requires an Expander Set (purchased separately) to connect to the drilling machine. These sets are size-specific and ensure secure attachment for optimal performance. Final core diameters will measure approximately 0.25in (6.4mm) smaller than the bit's nominal outside diameter.

The bit’s standard length of 14in (356mm) makes it capable of cutting cores up to 12in (305mm) in depth, making it versatile for a wide range of applications.

Key Features:

• High-Speed Cutting: Specifically designed for fast, efficient coring of concrete, asphalt, and other hard materials.
• Durable Diamond-Tipped Design: Ideal for wet-use applications and heavy-duty performance.
• Long-Lasting and Reusable: Can be refurbished to extend lifespan.
• Compatible with Multiple Drilling Machines: Connects to a core drill via a size-specific Expander Set.
• Meets Industry Standards: Compliant with ASTM and AASHTO specifications for quality and reliability.

Specifications:

• Application: Concrete and asphalt coring
• Nominal Bit Size (OD): 2-1/4in (57.2mm)
• Mounting Connection: Open-Head
• Length: 14in (356mm) with coring depth of up to 12in (305mm)

Standards Compliance:

• ASTM: ASTM C42/42M
• AASHTO: AASHTO T 24M/T 24

Applications:

This coring bit is ideal for contractors, engineers, and testing technicians who require precise, durable tools for sampling concrete or asphalt slabs. It is commonly used in construction quality control, road material testing, and structural analysis. With its wet-use capability and durable diamond-tipped design, it ensures clean, efficient cuts even in reinforced materials.

Note: Expander Sets are sold separately and are required for proper attachment to compatible drilling machines. Always ensure the correct size is used for optimal performance.
