Hole saw set Dedra 0793, wood core drill bits, Ø19–127 mm, 12 pcs

Set of wood core drill bits Dedra 0793 contains 12 hole saws with diameters from 19 mm to 127 mm designed for cutting clean circular holes in solid wood and common wood-based materials. The set is supplied in a compact case that keeps the hole saws organized and accessible on site. These hole saws suit tasks where precise round openings are required, such as door hardware installation, routing for pipes, cable penetrations and general carpentry work.

Advantages

The hole saw set covers a broad range of diameters, reducing the need to carry individual saws for different tasks. Each saw is produced for wood-cutting applications to deliver smooth cuts and minimize splintering when used with appropriate pilot bits and steady feed. The compact case protects the saws during transport and helps quickly select the required size. The set’s layout supports efficient workflow for professionals and DIY users who need multiple hole sizes in a single kit.

How to use

Select the hole saw size appropriate for the required opening and mount it to a compatible arbor or pilot bit in the drill chuck according to the arbor manufacturer’s instructions. Secure the workpiece and mark the center of the hole. Start drilling at low speed to engage the pilot bit and establish position, then increase speed and apply steady, even feed pressure while allowing the saw teeth to cut without forcing. Periodically clear sawdust from the cup to maintain cutting efficiency and reduce heat buildup. Finish the hole and deburr the edges as needed.

Usage recommendations

Use sharp pilot bits and appropriate drill speed for the saw diameter and wood type. For clean edges in veneered or laminated materials, support the exit side to reduce splintering. Avoid excessive side load on the saw to extend tool life and check regularly for wear or damage before use.
