Masonry Router Bit Set GEKO 9 pcs (30, 40, 65, 80, 100 mm + 2 adapters)

The GEKO 9-piece masonry/router bit set combines multiple diameters and adapters to provide a compact solution for cutting, shaping and channeling masonry materials such as brick, block and lightweight concrete. Designed for use with compatible angle grinders and routers where applicable, the set covers common hole and groove sizes used in renovation, installation and finishing work.

Advantages

This set contains five commonly used diameters (30, 40, 65, 80 and 100 mm) together with two adapters for tool compatibility, reducing downtime caused by searching for individual cutters. The variety of sizes allows efficient removal of material for cable routing, pipe installation, ventilation ducts and decorative openings. The adapters enable use with different spindle sizes and help adapt the bits to a wider range of angle grinders or routers. The construction is intended for masonry applications, providing consistent cutting performance when used with appropriate power tools and proper technique.

Suitable for

• Cutting circular holes in brick and block for pipe or conduit entries
• Creating channels and recesses for wiring, pipes and ducts
• Renovation tasks that require removal of masonry material
• Detailing and finishing edges on masonry elements

Key specifications

• Set composition: 5 cutter diameters and 2 adapters
• Cutter diameters: 30 mm, 40 mm, 65 mm, 80 mm, 100 mm
• Intended material: brick, block, lightweight masonry and similar materials
• Compatibility: suitable for use with compatible angle grinders and routers when fitted with the correct adapter
• Typical applications: hole cutting, channeling, recessing and edge work in masonry

How to use

Select the cutter diameter appropriate for the required hole or channel. Fit the chosen cutter to the tool using the matching adapter to ensure secure mounting. Mark the working area on the masonry surface, secure the workpiece if possible, and start the tool at low speed to establish the cut, then increase speed as necessary following the tool manufacturer’s guidance. Apply steady, controlled pressure and avoid forcing the cutter; make several passes if needed to reach the desired depth. After finishing the cut, stop the tool, allow the cutter to cool, and clear debris before changing sizes or storing the set.

Usage recommendations

Use appropriate personal protective equipment — eye protection, dust mask, hearing protection and gloves — and ensure adequate dust extraction or ventilation when cutting masonry. Match the adapter and tool speed to the cutter diameter, and follow the angle grinder or router manufacturer’s instructions for safe operation. For best results, perform test cuts in scrap material to confirm speed, feed and clearance before working on the final surface.
