Segmented blade FEIN 63502169210 for porous concrete and tile

The FEIN 63502169210 segmented blade is designed for cutting out damaged tile joints, cutting slots in plaster, porous concrete and similar building materials, and for cleaning and reworking deck joints. It is a cost‑effective alternative to diamond tools and has a segmented shape that enables work in corners and along edges with reduced risk of overcutting. The blade has an approximate cutting width of 2.2 mm and a diameter of 90 mm, compatible with FEIN MultiMaster QuickStart and Top models.

Advantages

Segmented design allows precise work in corners and on edges without overcutting. Suitable for a variety of softer masonry and tile joint materials, it provides a lower‑cost option compared with diamond blades while maintaining effective cutting performance. The compact 90 mm diameter is suitable for overhead and detail work in confined spaces.

Suitable for

• Removing damaged tile joints
• Cutting slots in plaster and porous concrete
• Cleaning and reworking deck or floor joints
• Detail work near corners and edges

How to use

Install the segmented blade on a compatible FEIN MultiMaster model according to the tool manufacturer’s mounting instructions. Secure the workpiece if possible and work with steady, controlled passes; avoid forcing the blade to allow the segments to cut cleanly. For best results on joints and grooves, maintain a consistent angle and feed rate. Replace the blade if cutting performance decreases or if excessive wear is visible.

Recommendations

Wear appropriate personal protective equipment, including eye protection, gloves and a dust mask. Use lower feed pressure on harder or abrasive substrates and avoid using the blade on very hard epoxy resin or dense cement joints to prevent damage and premature wear.
