Angle Cutting Attachment for Angle Grinder 115–125 mm, 45° Cutting, GEKO G30127

The Angle Cutting Attachment for Angle Grinder 115–125 mm, 45° Cutting, GEKO G30127 is an accessory that transforms a standard 115–125 mm angle grinder into a guided tool for making precise 45° bevel cuts. Designed for use with common abrasive and cutting discs of the compatible diameter, this attachment offers a fixed cutting angle and a guide interface that helps stabilize the grinder during straight and angled cuts in metal, pipework and various construction materials. It is intended for workshop and on-site use where repeatable angled cuts and controlled cutting depth are required.

Advantages

The attachment provides a stable guide for 45° cuts, reducing user fatigue and improving repeatability compared with freehand cutting. Its compatibility with widely used 115–125 mm discs makes it easy to integrate into existing toolsets without changing the grinder. The design supports safer, more controlled cuts by keeping the grinder aligned to a fixed plane, which helps achieve cleaner bevels and more accurate joint preparation for welding or fitting.

Suitable for

• Making 45° bevel cuts on metal sheets and profiles
• Preparing pipe ends for welding or joining
• Cutting angled edges on construction materials such as metal trim or brackets
• Workshop projects and on-site fabrication where guided angled cutting is needed

When it may not be suitable

This attachment is not intended for use with grinders that accept discs outside the 115–125 mm range. It may not be suitable for precision woodworking or finish carpentry where different cutting tools and finer control are required. Very thick structural sections or materials requiring specialised cutting methods may exceed the attachment's effective cutting depth or the capacity of a standard angle grinder.

Key specifications

• Compatible disc diameter: 115–125 mm
• Fixed cutting angle: 45°
• Intended use: guided angled cutting for angle grinders
• Typical applications: metal, pipework, thin construction materials
• Mounting: designed to attach to standard angle grinder guard/interface for the specified disc sizes

How to use

Mount the attachment to an angle grinder compatible with 115–125 mm discs following the attachment's mounting points and the grinder manufacturer's safety instructions. Fit an appropriate cutting or abrasive disc for the material to be cut, ensure the disc is rated for the grinder's speed, and tighten all fasteners. Position the guide against the workpiece so the attachment sets the grinder at a 45° angle, start the grinder and make controlled passes along the marked cutting line. Use steady feed speed, avoid excessive pressure, and allow the disc to do the cutting to reduce the risk of kickback or binding.

What to consider before purchase

• Verify your angle grinder accepts 115–125 mm discs and that the attachment fits the grinder's guard/interface
• Confirm the thickness and type of material you plan to cut are within the cutting capacity of your grinder and disc
• Ensure you have appropriate discs rated for the grinder's RPM and the intended material
• Check that the attachment's mounting method is compatible with your grinder model and follow safety guidelines

Usage recommendations

For safer and more accurate results, wear appropriate personal protective equipment (eye protection, gloves, hearing protection) and secure the workpiece. Use discs suitable for the material, check disc condition regularly, and perform test cuts on scrap material to confirm alignment and cutting depth before working on the final piece.
