Hole Saw DEDRA H1238 for Stone and Concrete 6.2 cm

The DEDRA H1238 hole saw for stone and concrete with a 6.2 cm cutting diameter is engineered for drilling clean, precise round openings in masonry materials. Designed to be used with compatible power drills and appropriate pilot bits, this hole saw targets tasks such as installing pipes, conduits, anchors and fixtures where a reliable circular cut in stone or concrete is required. The tool’s construction balances cutting performance and wear resistance for repeated use on hard substrates.

Advantages

This hole saw combines a 6.2 cm diameter optimized for common installation needs with a robust body and cutting edge geometry intended for efficient removal of material in stone and concrete. The design delivers straight, accurate cuts and reduced chipping when operated with correct drilling speed and support. Its construction aims to provide a long tool life under typical jobsite conditions and to maintain consistent hole quality for follow-on installation work.

Suitable for

• Drilling circular openings in concrete walls and floors
• Making holes in stone, brick and masonry for plumbing and electrical conduits
• Creating openings for anchors, sockets and ventilation ducts
• Renovation and retrofit work requiring precise, repeatable holes

Key specifications

• Cutting diameter: 6.2 cm
• Intended material: stone and concrete
• Compatibility: designed for use with standard power drills and appropriate pilot bits or arbor attachments
• Typical application: through-holes in masonry for installations and fixtures

How to use

Select a suitable drill with matching arbor or pilot bit, mark the hole position and secure the work surface where possible. Begin drilling at low speed to establish the cut and then increase speed as recommended for the chosen drill and masonry material. Apply steady axial pressure without forcing the tool; periodically withdraw to clear dust and allow cooling. Use water cooling only if the manufacturer of the drill and arbor permits it and if appropriate for the specific job to reduce heat and dust. Finish the hole by removing debris and checking dimensions before fitting any fixtures.

Usage recommendations

For best results, use appropriate personal protective equipment including eye and respiratory protection, clamp or support the workpiece, and select drill speed and feed suited to the hardness of the masonry. Replace the hole saw if wear affects cutting quality, and use a compatible arbor and pilot bit to ensure concentric and stable drilling.
