Diamond Core Drill Guide 4–75 mm, Expert+ MN-76-298

The Diamond Core Drill Guide 4–75 mm, Expert+ MN-76-298 is a positioning aid designed to stabilize diamond core drills with diameters between 4 and 75 mm. The guide helps maintain alignment and control for hand-held or machine-mounted core drills when working on suitable materials, enabling repeatable hole placement and improved drilling precision. Constructed to mate with a range of diamond hole saws, it supports tasks where consistent centring and steady feed are important.

Advantages

This drill guide provides a stable reference for core drilling operations, reducing lateral movement and helping to protect the drill bit and work surface. It is compatible with a broad diameter range, eliminating the need for multiple guides for different hole sizes within its span. The guide's design supports both manual and machine-mounted use, allowing for versatile application and easier control of drilling depth and angle.

Suitable for

• Drilling precise holes in ceramic, porcelain, glass, and masonry when using appropriate diamond core bits
• Repeatable hole placement in tiling and sanitary installations
• Installation tasks requiring accurate centring for pipes, conduits, and anchors
• Controlled core drilling in renovation and construction work with hand or stand-mounted drills

Key specifications

• Supported drill diameter range: 4–75 mm
• Intended use: positioning and stabilization for diamond core drills
• Compatibility: suitable for use with hand-held and machine-mounted core drills and diamond hole saws within specified diameter range
• Primary function: improve alignment, reduce lateral movement, enable repeatable hole placement

How to use

Secure the guide to the workpiece according to its fitting method and ensure the surface is clean and stable before drilling. Select a diamond core bit within the 4–75 mm range and fit it to the drill; align the bit with the guide and start drilling at low speed to establish the pilot contact. Apply steady, moderate pressure and maintain the drill perpendicular to the work surface, increasing speed as recommended for the material and drill bit. Periodically withdraw the bit to clear debris and cool the diamond segment if required by the drilling conditions.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses, gloves, and a dust mask. Match the diamond core bit type and drilling speed to the material being drilled and employ water cooling where recommended to extend bit life and improve hole quality. Inspect the guide and drill setup before each use to ensure secure mounting and correct alignment.
