Rear Disc Grinder Flex BP-M D115 M14 — Flex 240311, 115 mm disc, M14 spindle

The Flex Rear Disc Grinder BP-M D115 M14 is a compact rear-mounted angle grinder engineered for use with 115 mm abrasive discs and an M14 threaded spindle. Designed for surface grinding, rust and paint removal, weld seam finishing and edge preparation, this tool combines a rear disc configuration with a compact form factor to fit confined workshop and on-site applications. Its layout provides improved access to narrow areas and steady handling when working on metal components and other materials.

Advantages

The rear-mounted disc arrangement allows closer access to edges and recessed surfaces compared with conventional side-head grinders, improving control in tight spaces. The compact housing supports stable handling and reduced operator fatigue during extended tasks. Compatibility with standard 115 mm abrasive discs and an M14 spindle thread ensures easy replacement of consumables and availability of discs for grinding, sanding and finishing. The design is suitable for both preparatory work and finishing operations on metal surfaces.

Suitable for

• Surface grinding and material removal on steel and other metals
• Rust and paint removal from structural and small parts
• Weld seam trimming, blending and finishing
• Edge preparation before welding or coating
• Work in confined areas where rear-disc access improves reach

Key specifications

How to use

Fit a compatible 115 mm abrasive disc onto the M14 spindle and tighten according to the tool manufacturer's torque guidance. Hold the tool with a firm, two-handed grip and position the rear-mounted disc against the work surface at a controlled angle. Use steady, even passes to remove rust, paint or material, avoiding excessive pressure which can overheat the disc or workpiece. Allow the tool and disc to reach full speed before contacting the surface and follow safe startup and shutdown procedures. Replace worn discs promptly and verify the disc type is appropriate for metal or the specific substrate.

Usage recommendations

Use personal protective equipment including eye protection, gloves, and hearing protection when operating the grinder. Select abrasive discs rated for the intended task and material. Maintain the tool according to the manufacturer's instructions, inspect discs for damage before use, and avoid exceeding recommended disc speed or applying excessive side pressure.
