OMT Joint Cutters

About OMT Joint Cutters

OMT (Oscillating Multi-Tool) joint cutters are specialised blades designed for removing old grout, sealant, and soft materials from joints and gaps in various surfaces. These precision accessories fit Starlock and Starlock Max oscillating multi-tools, providing tradespeople and keen DIYers with an efficient solution for joint preparation and renovation work. MyToolShed.co.uk stocks professional-grade OMT joint cutters from leading manufacturers like Bosch Professional, engineered to deliver clean, controlled cutting in confined spaces.

Available in different widths and lengths, these blades feature carbide-grit or diamond-coated cutting edges that make short work of removing silicone, acrylic sealants, and soft grouting materials without damaging surrounding tiles or surfaces. The universal Starlock fitment system ensures quick, tool-free blade changes and secure attachment during operation, making them essential accessories for bathroom and kitchen refurbishment projects.

Applications

OMT joint cutters are invaluable tools for various trades and applications, including:

• Tilers and bathroom fitters: Removing old grout and sealant from between tiles during renovation work
• Kitchen fitters: Cleaning out worktop joints and preparing surfaces for fresh sealant application
• Decorators: Stripping degraded silicone from window frames, skirting boards, and sanitary ware
• Property maintenance professionals: Refurbishment projects requiring joint preparation and cleaning
• DIY enthusiasts: Home improvement tasks such as re-sealing showers, baths, and kitchen surfaces
• Window fitters: Removing old sealant from frames and preparing for new installations

Choosing The Right OMT Joint Cutters

When selecting OMT joint cutters at MyToolShed.co.uk, consider these essential factors:

Blade width: Narrow blades (around 28mm) suit standard tile joints and tight spaces, whilst wider options (32mm and above) cover more surface area for faster material removal in larger joints.

Blade length: Standard-length blades work well for most applications, but long-reach versions provide better access to deeper joints and recessed areas without the tool housing obstructing your work.

Fitment compatibility: Ensure your blade matches your multi-tool system. Starlock Max blades require compatible tools, whilst Universal Starlock fits most modern oscillating multi-tools with the standardised mounting system.

Material type: Carbide-grit blades excel at soft materials like silicone and acrylic sealants, making them ideal for bathroom and kitchen applications where these products are commonly used.

Power supply: If purchasing a complete oscillating multi-tool, consider whether corded 240v models or cordless battery options best suit your working environment and power access requirements.

Frequently Asked Questions

Can OMT joint cutters remove hard grout?

Whilst designed primarily for soft materials like silicone sealant and acrylic grout, carbide-grit joint cutters can remove softer cement-based grouts. For harder grouting materials, dedicated grout removal blades with diamond or tungsten carbide construction deliver better results.

How long do OMT joint cutter blades last?

Blade longevity depends on usage intensity and material hardness. When used correctly on appropriate soft materials, quality blades from brands like Bosch Professional typically handle multiple projects before requiring replacement. Regular cleaning and avoiding excessive pressure extends blade life considerably.

Are these blades compatible with all oscillating multi-tools?

Starlock and Universal Starlock blades fit most modern oscillating multi-tools that feature the standardised Starlock mounting system. Always verify your tool's compatibility before purchase, as older models may use different fitment types.
