GRINOXA 55-Piece Oscillating Tool Blade Set, 44mm HCS and Titanium Blades

For trimming wood or plastic during a repair, the GRINOXA blade set gives you multiple oscillating-tool blades in one kit. Its 44mm blades include high-carbon steel options for wood and plastic, plus titanium blades for soft metal and other listed materials.

If your projects mainly involve wood and plastic, the 53 high-carbon steel blades provide a dedicated option for those cuts. For jobs that also call for soft metal or non-hardened nails, the set includes two titanium blades.

The universal-style interface is designed for broad oscillating-tool compatibility. Check that your tool uses a compatible interface, these blades are not suitable for Starlock systems.

The essentials

This 55-piece kit contains 53 high-carbon steel blades and two titanium blades, all measuring 44mm. The high-carbon steel blades are intended for wood and plastic. The titanium blades can be used for soft metal, non-hardened nails, plastic, plasterboard, aluminum, copper, and other hard materials. They are not intended for bolts or screws, and the high-carbon steel blades are not suitable for metal or nails.

The blades have length markers on both sides: one side uses inches and the other millimeters. This gives you a reference while positioning a cut, which is useful for trim work, adjustments around openings, or other tasks where cut depth matters. A black electrophoretic finish on the high-carbon steel blades is described as helping protect against corrosion.

How it fits

The blades use a universal interface and are listed as compatible with tools from brands including DeWalt, Ryobi, Milwaukee, Fein, Hitachi, Black & Decker, Chicago, and Craftsman. Compatibility depends on the tool’s blade interface, so match that connection before fitting a blade. The set is not compatible with Starlock tools.

For a project centered on wood or plastic, choose a high-carbon steel blade. When the cut involves soft metal or a non-hardened nail, use one of the titanium blades instead. Selecting the blade for the material helps keep each task aligned with the intended use of the blade.

Getting the most from it

A practical use is keeping the kit on hand for varied repair and remodeling tasks: use an HCS blade for wood or plastic cuts, then switch to a titanium blade when the work calls for soft metal or plasterboard. The side markers provide a quick visual reference as you position the blade. Follow the material guidance for each blade, and avoid using the titanium blades on bolts or screws.

Buyers describe the blades as useful for multitool work and report positive experiences with their functionality and quality. Feedback on sharpness is mixed, so choose the blade by material and task rather than assuming every blade will feel the same in use.

Questions before you buy

What comes in the set? It includes 53 high-carbon steel blades and two titanium blades, each 44mm.

Which blades should I use for metal? Use a titanium blade for soft metal, aluminum, copper, or non-hardened nails. The high-carbon steel blades are not intended for metal or nails, and the titanium blades are not for bolts or screws.

Will the blades fit my oscillating tool? They use a universal-style interface and are listed for a range of brands, including DeWalt, Ryobi, Milwaukee, and Fein. They do not fit Starlock systems, so check your tool’s interface before installation.

Buying verdict

For a multitool owner who wants blades for both wood-and-plastic work and selected soft-metal cuts, this GRINOXA set brings those uses together in a 55-piece kit. The two blade types, 44mm format, and dual-unit length markers make it a practical choice for keeping different cutting tasks organized around one compatible oscillating tool.
