Hole saw Dedra DED1520/67 — diameter 6.7 cm, 1 piece

DEDRA DED1520/67 hole saw with a 6.7 cm cutting diameter is a single-piece accessory intended for creating circular openings in materials compatible with its tooth geometry. Designed primarily for woodworking and cutting through soft plastics and similar substrates, this hole saw attaches to drills or drill adapters to make precise round holes for installing fixtures, routing cables, or fitting pipes. The tool is intended for use where a clean circular cut is required and where material thickness and hardness match the saw’s design.

Advantages

The hole saw offers a straightforward single-piece design that simplifies mounting and removal on standard drill arbors. Its tooth geometry is optimized for clean cutting in wood and soft plastic, reducing the need for secondary finishing. Lightweight and compact, the saw occupies minimal storage space and is easy to handle during setup. The tool is compatible with common drills and adapters, enabling use in a variety of installation and renovation tasks where circular holes are needed.

• Design: single-piece hole saw with tooth geometry for cutting soft materials

How to use

Secure the hole saw to a compatible drill or arbor according to the drill manufacturer’s instructions. Mark the center point of the desired hole on the workpiece and, if available, use a pilot bit or guide to keep the saw steady. Start drilling at low speed to establish the cut, then increase speed as appropriate for the material while applying steady, even pressure. Clear chips periodically to maintain cutting efficiency and avoid binding. After cutting, remove the hole saw and deburr the edge of the hole if necessary.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed rate to the material being cut; lower speeds are preferable for plastics to reduce melting. Ensure the workpiece is securely clamped before drilling and inspect the saw before use for wear or damage.
