Techniflex INCOFLEX grinding wheel M278-125-6.0-22C24R is a 125 x 6.0 mm abrasive disc engineered for shaping, grinding and dressing natural and engineered stone. Designed to fit standard angle grinders with a 22 mm bore, this wheel features a C24R grit configuration intended to provide controlled material removal and a balanced surface finish on granite, marble, sandstone and composite stone panels.
Advantages
The wheel combines a narrow 6.0 mm thickness for precise edge work with an abrasive composition optimised for stone applications. Its size and bore make it compatible with common handheld grinders, enabling straightforward replacement and secure mounting. The C24R grit distribution offers a compromise between cutting speed and surface smoothing, allowing both shaping and initial finishing tasks to be completed with a single disc.
Suitable for
- Shaping and profiling edges of natural stone (granite, marble)
- Grinding and smoothing engineered stone and quartz surfaces
- Removing small amounts of material for fitting or leveling stone slabs
- On-site stone work with angle grinders in construction and stonemasonry
When it may not be suitable
This disc is intended specifically for stone materials and may deliver reduced performance on metals, wood or masonry different from natural or engineered stone. For very aggressive stock removal, deep cutting, or precision polishing to high-gloss finishes, specialised blades or polishing systems may be more appropriate than this grinding wheel.
Key specifications
- Diameter: 125 mm
- Thickness: 6.0 mm
- Bore (arbor) diameter: 22 mm
- Grit / bond designation: C24R (suitable for stone grinding)
- Intended use: grinding and dressing of natural and engineered stone
How to use
Fit the grinding wheel to an angle grinder with the matching 22 mm arbor, ensuring the grinder is unplugged or the battery removed during installation. Tighten the mounting nut securely according to the grinder manufacturer’s instructions and confirm the wheel is free of cracks or defects before use. Operate the grinder at the recommended speed range and apply steady, even pressure across the stone surface; avoid excessive force that can cause glazing or premature wear. Use adequate cooling or intermittent passes on heat-sensitive materials and clean the surface between passes to check progress.
What to consider before purchase
- Confirm your angle grinder accepts a 125 mm disc and has a 22 mm arbor or suitable adapter
- Match the wheel thickness and grit to your task — 6.0 mm thickness is suited for edge shaping and moderate material removal
- Ensure the disc is intended for the specific stone type you will work with (natural vs engineered stone)
- Check grinder speed (RPM) compatibility with abrasive wheel ratings
Usage recommendations
Wear appropriate PPE including eye and respiratory protection, gloves and hearing protection. Work in a well-ventilated area, secure the stone piece, and inspect the wheel before each use. For best results, start with light passes to establish the profile, then progressively increase contact to achieve the desired surface. Replace the wheel if any damage or excessive wear is observed.
