The CMT OMM-X4 General Purpose Set for Multi-Cutters is a 4-piece oscillating tool blade kit engineered to handle the widest range of everyday cutting tasks - from precise plunge cuts in wood and chipboard to aggressive cuts through sheet metal, copper, aluminium profiles, and even masonry materials like porous concrete. Featuring both HCS blades with Japanese Toothing for clean, accurate cuts in wood and composite board products, and BIM blades capable of slicing through embedded nails up to 5mm in diameter, this set equips tradespeople and DIYers with the right blade for nearly any job encountered on site.

Key Features

• 2 HCS blades with Japanese Toothing for wood, chipboard, plasterboard, and plastics - fine tooth geometry delivers smooth, tear-free cuts in sheet goods and timber framing applications where finish quality matters.
• 2 BIM (Bi-Metal) blades for wood, blockboard, plasterboard, fiberglass, epoxy, soft plastics, sheet metal, copper, and aluminium pipes and profiles - the bi-metal construction withstands the heat and stress of cutting hard and varied materials that would quickly dull standard HCS blades.
• BIM blades cut through embedded nails up to 5mm in diameter and masonry such as porous concrete - tackles demolition and renovation scenarios where hidden fasteners or masonry would stop lesser blades, reducing the need to swap tools mid-task.
• 4-piece set in a single package - covers the most common oscillating tool cutting applications without purchasing individual blades separately, lowering overall tooling cost.

Why This Product

• A single kit covers cutting in wood, chipboard, plasterboard, plastics, fiberglass, sheet metal, copper, aluminium, and even masonry - reducing the number of blade sets a contractor needs to carry to the job site.
• The BIM blades are rated to cut through nails embedded in wood up to 5mm in diameter, making this set genuinely suitable for renovation and demolition work where reclaimed lumber or hidden fasteners are a constant challenge.

Frequently Asked Questions

What is the difference between the HCS blades and the BIM blades included in this set?

The HCS blades feature Japanese Toothing optimized for clean cuts in wood, chipboard, plasterboard, and plastics. The BIM (Bi-Metal) blades are built for harder and more varied materials - including fiberglass, epoxy, sheet metal, copper, aluminium pipes and profiles, masonry like porous concrete, and even nails embedded in wood up to 5mm in diameter. Together, the two blade types cover a much broader range of applications than either type alone.

Will these blades fit my existing multi-cutter?

All four blades in this set use a Universal Arbor mounting interface, which is designed to fit most multi-cutter brands currently on the market. Check that your oscillating tool accepts a universal arbor blade before purchasing.

Can the BIM blades in this set be used for demolition work involving hidden nails?

Yes. The BIM blades are rated to cut through nails embedded in wood up to 5mm in diameter, making them well suited for renovation and demolition applications where fasteners may be concealed within reclaimed or structural lumber.
