## Summary description

The DEDRA H1236 hole saw is designed for drilling in stone and concrete. With a diameter of 4.2 cm, it is suitable for various construction tasks. This durable tool ensures precise cuts and is ideal for professionals and DIY enthusiasts alike.

## Long description

The DEDRA H1236 hole saw with a 4.2 cm cutting diameter is engineered for drilling clean, precise holes in stone and concrete. Manufactured for use with compatible drill/drivers, this hole saw is intended to deliver consistent performance on masonry surfaces where standard wood or metal hole saws would not suffice. Its design focuses on durability and accurate cutting for frequent construction and renovation tasks.
Advantages
This hole saw offers a 4.2 cm diameter optimized for common masonry openings and a tooth geometry suited to abrasive materials such as stone and concrete. Constructed from hardened materials to resist wear, it provides stable cutting action and longer service life under typical jobsite conditions. The tool’s compatibility with standard hole saw arbors and its balanced construction reduce vibration and improve hole roundness.
Suitable for
Creating pass-throughs for pipes and conduits in concrete walls
Installing electrical boxes and fixtures in masonry
Drilling anchor or fastener clearances in stone and blockwork
Renovation and retrofit openings in plastered or tiled masonry surfaces
Key specifications
Cutting diameter: 4.2 cm
Intended material: stone and concrete (masonry)
Design: abrasive/toothed rim suitable for hard, brittle substrates
Compatibility: for use with compatible drill/drivers and appropriate arbors
Durability features: wear-resistant construction for extended use on masonry
How to use
Secure the hole saw to a compatible arbor and attach it to a drill with sufficient power and torque for masonry work. Mark the drilling position and, if possible, start with a pilot drill or centre punch to stabilise the saw. Use steady, moderate feed pressure and maintain the drill at a right angle to the surface. Operate at recommended rotational speeds for masonry hole cutting, and withdraw periodically to remove dust and allow cooling. After completing the cut, clean the bore and inspect the edge for any irregularities before installing fixtures.
Usage recommendations
Use a drill with an appropriate hammer function switched off (rotary mode) or follow manufacturer guidance for masonry hole saws; apply water cooling when drilling deep holes to reduce heat and dust where applicable. Wear eye, respiratory and hand protection, and ensure secure workpiece support to prevent binding or sudden movement.
