List pile Metabo 628298000 12,5 cm

Dia-CD3 wall slotting blade, 125 x 28.5 x 22.23 mm (Metabo 628299000) is a professional‑grade diamond cutting segment assembly designed for fast and comfortable cutting of wall slots in a variety of materials. It fits circular saws and wall chasers that accept a 22.23 mm bore and is intended for creating clean, customised chases for cables and conduit with maximum cutting widths of 20 mm (two rows, Metabo 628298000) or 30 mm (three rows, Metabo 628299000).

Advantages

The interlaced arrangement of diamond segments eliminates the need to chisel away the centre, reducing operator workload and enabling one‑step cutting that saves time. Material is removed cleanly and completely from the slot, which lowers dust and debris compared with conventional chiselling. The design allows precise, repeatable slots suitable for individual lines or for 20 mm and 25 mm empty conduits.

Suitable for

• Cutting wall slots in masonry, concrete and similar building materials
• Creating chases for electrical cables and empty conduit (Ø 20 mm and Ø 25 mm)
• Use with compatible circular saws or wall chasers that accept a 22.23 mm bore

How to use

Mount the blade on a compatible circular saw or wall chaser with a 22.23 mm arbor following the tool manufacturer's mounting and safety instructions. Mark the desired slot line on the wall, secure the work area, and cut the slot in one or multiple passes as required to reach the desired depth and width. After cutting, remove residual material from the slot and finish edges as needed.

Recommendations

Use appropriate personal protective equipment (eye, hearing and respiratory protection) and follow the saw and blade manufacturer's recommendations for maximum speed, cooling/lubrication, and safe operation. Ensure the tool's maximum RPM is compatible with the blade and avoid side pressure on the blade to prolong life and ensure clean slotting.
