Product information

Description

The Milwaukee WCHP Diamond Core Bit is a professional-grade accessory engineered for demanding core drilling tasks. Featuring a standard 1 1/4" connection, this robust core bit is built to deliver high efficiency and precise drilling performance in professional construction and renovation environments. With a 72 mm diameter, 420 mm working length, and 500 mm total length, it provides the reliability and structural integrity expected from Milwaukee equipment.

Advantages

This diamond core bit ensures high drilling speed and clean, accurate holes thanks to its precision-engineered diamond segments. The durable construction supports extended operational life under rigorous working conditions, reducing the frequency of tool replacements. Its optimized design facilitates smooth dust and debris evacuation during the drilling process, contributing to consistent performance and reduced operator fatigue.

Suitable for

  • Drilling precise holes in concrete and reinforced concrete structures
  • Professional construction, renovation, and installation projects
  • Routing utility pipes, cables, and ventilation ducts through masonry

When it may not be suitable

This core bit is not designed for handheld drilling without a secure core drill stand, as the high torque requires stable machine mounting. It is also not recommended for drilling through heavy steel beams or non-masonry materials where diamond segments cannot function efficiently.

Key specifications

  • Connection type: 1 1/4 inch
  • Diameter: 72 mm
  • Working length: 420 mmTotal length: 500 mm
  • Compatible tool: Core drills

How to use

Mount the diamond core bit securely onto a compatible core drill using the 1 1/4" threaded connection. Ensure the drilling machine is firmly secured to a stable drill stand to safely handle operational torque. Align the bit with the marked drilling point and initiate drilling with an appropriate rotational speed and controlled feed pressure. Apply water cooling if required by the material specifications to maximize segment lifespan and maintain cutting efficiency.

What to consider before purchase

  • Verify that your core drill machine supports the 1 1/4 inch connection type
  • Check that the 72 mm diameter and 420 mm working length match your specific project requirements
  • Ensure access to a stable core drill stand for safe and accurate operation
Usage recommendations: Always use appropriate personal protective equipment including eye protection and hearing guards during operation. Inspect the diamond segments regularly for wear and ensure a stable water supply for cooling where applicable.
