FEIN 63903212018 E-Cut Long-Life StarlockPlus Bi-Metal Plunge Cut Blade, 2-Pack

Professional carpenters and renovation crews rely on this FEIN E-Cut Long-Life plunge cut blade when cutting precise openings in hardwood flooring, trimming door casings, or slicing through copper pipe and plasterboard. The bi-metal construction combines an HSS cutting edge with a flexible spring-steel body, so the blade resists breakage and stays sharp far longer than standard HCS blades. The StarlockPlus mount snaps directly into all FEIN MultiTools and other Starlock-compatible oscillating tools without adapter, delivering maximum power transfer and reduced vibration.

Why choose it

The Long-Life designation means the bi-metal teeth are hardened for extended service life, making this blade a cost-effective choice for professionals who cut abrasive materials daily. The universal tooth geometry provides fast, clean cuts in both wood and metal, while the 50 mm immersion depth allows deep plunge cuts in tight spaces. The StarlockPlus interface ensures a secure, tool-free blade change and optimal oscillation transfer, reducing wear on both blade and tool.

Ideal use cases

• Flush-cutting door jambs and baseboards during flooring installation
• Creating precise cutouts in kitchen countertops for sinks and cooktops
• Cutting copper pipes and aluminum profiles in plumbing and HVAC work
• Trimming plasterboard and drywall for electrical boxes and recessed lighting
• Removing damaged sections of hardwood or laminate flooring

Good to know

FEIN is the inventor of the oscillating multi-tool, and these original accessories are engineered to the same exacting standards. The blade is sold in a pack of two, so you always have a spare on the job site. For best results, use a moderate oscillation speed and let the blade do the work—do not force it. The bi-metal construction is not suitable for hardened steel or masonry; choose a carbide blade for those applications.
