55 Pack Bi-Metal Saw Blades 34MM & 44MM - Durable Multitool Blades

Our review of the 55 Pack Bi-Metal Saw Blades looks at who will get real value from a mixed-size kit of 34mm and 44mm oscillating tool blades. The bottom line: this set is aimed at homeowners, handymen, and renovators who need a large assortment of replacement blades for cutting soft metal, hardwood, PVC and other common materials; the biggest reason to buy is the promise of longer life from the bimetal construction and a comprehensive selection so you rarely run out mid-job. This review focuses on real-world cutting use and notes where users reported mixed durability.

Key Features

• Bi-metal construction: The blades combine bimetal and high-carbon steel for greater wear resistance and an expected longer service life than standard blades.
• Two common sizes: The kit includes both 34mm and 44mm blades so users can match blade size to tight or open cuts without buying separate packs.
• High-quality coating: A protective coating on the teeth helps reduce oxidation and prolong blade life when used appropriately.
• Marked scale and handle design: Accurate scale markings and a bent handle design reduce impact force and help improve cutting control and efficiency.
• Versatile cutting: These blades are suitable for soft metals, copper pipes, hard woods, PVC and hard plastics, making them useful for renovation and repair tasks.
• Care guidance included: Instructions warn against cutting bolts or screws and recommend cooling periods and flat insertion to prevent premature damage.

Who It's For

This 55-pack is best for DIYers, maintenance workers and small contractors who value a large selection of replacement blades for oscillating tools and perform varied cutting tasks around the home or jobsite. The assortment covers common needs from floor trimming to bathroom and window repairs.

Those who need blades for heavy industrial, continuous-duty metal cutting or who require guaranteed OEM bimetal certification should look for purpose-built professional blades; some users reported mixed metal content and variable durability, so buyers seeking enterprise-grade lifetime performance may prefer higher-end single-purpose blades.

Pros & Cons

Pros

• Wide assortment of 34mm and 44mm blades reduces the frequency of reordering and covers many common tasks.
• Bi-metal teeth and coating help resist wear and oxidation for longer life in typical household use.
• Visible scale markings and ergonomic bending reduce impact and can improve accuracy when cutting.
• Good value for money for users who need quantity and versatility rather than premium specialty blades.

Cons

• Durability reports are mixed: some users find blades go dull sooner than expected, so intensive or repeated heavy-duty metal cutting may reduce lifespan.
• Several buyers noted inconsistent metal content versus expectations, so quality may vary between pieces in the pack.
