Cutting Disc for Aluminum Makita M B-45369 230 x 1.9 mm

Makita cutting disc for aluminum M B-45369, size 230 x 1.9 mm, is a thin abrasive wheel developed for cutting non-ferrous metals and aluminium profiles. The 1.9 mm thin section minimises material loss and delivers precise, narrow kerfs, making it suitable for tasks that require controlled, clean cuts. Compatible with standard angle grinders that accept 230 mm discs, this cutting disc is intended for workshop and construction use where efficient aluminium cutting is needed.

Advantages

The thin 1.9 mm cutting edge reduces waste and allows for more accurate, straighter cuts in aluminium and other non-ferrous metals. The abrasive composition is formulated to cut softer metals efficiently while maintaining acceptable disc life under normal working conditions. Designed for use on 230 mm angle grinders, the disc balances cutting speed and control to support consistent results on profiles, sheets and tubing.

Suitable for

• Cutting aluminium profiles, sheets and tubing
• Workshop metalworking and fabrication
• Construction tasks requiring precise non-ferrous metal cuts
• On-site trimming and fitting of aluminium components

Key specifications

• Diameter: 230 mm
• Thickness: 1.9 mm
• Intended material: aluminium and non-ferrous metals
• Tool compatibility: angle grinders for 230 mm discs
• Typical application: abrasive cutting

How to use

Fit the disc to a compatible 230 mm angle grinder following the grinder manufacturer’s mounting instructions. Ensure the disc is mounted with the correct rotation direction and that the grinder’s guard is in place. Secure the workpiece and mark the cut line, then perform steady, even passes without excessive side pressure to avoid chipping or disc damage. Allow the disc to do the cutting and maintain moderate feed speed to control heat and wear. Inspect the disc for cracks or damage before each use and replace immediately if any defects are found.

Usage recommendations

Use appropriate personal protective equipment including eye and face protection, hearing protection and gloves. For best results on aluminium, clean the work area of debris and avoid prolonged contact in one spot to reduce heat buildup. Store discs flat in a dry environment and follow the angle grinder and disc safety ratings for speed limits and mounting instructions.
