9 in 4/6 TPI Reciprocating Saw Blades 25 Pack - Faster, Longer Life

In this review the 25 pack of 9 in 4/6 TPI reciprocating saw blades is judged as a practical choice for users who need a durable, fast-cutting blade for general wood and nailed-wood work. The reviewer found the blades particularly useful for outdoor pruning and demolition tasks because the bi-metal construction with 8% cobalt and a non-stick coating delivers noticeably longer life and steady cutting speed compared with ordinary replacement blades. For homeowners and tradespeople who value fewer blade changes and confident performance on mixed wood tasks, these blades stand out.

Key Features

• High compatibility: The 9 in blades fit all brands of reciprocating saws so swapping blades is hassle free across different tools.
• Bi-metal with 8% cobalt: The cobalt-enhanced steel increases toughness and resists wear for longer service life when cutting hard or nail-embedded wood.
• 4/6 TPI tooth pattern: The 4/6 teeth per inch balance faster cutting speed with acceptable finish for pruning, demolition, and composite wood tasks.
• Non-stick coating: The coating reduces material buildup and helps the blade stay cooler, extending usable life during longer cuts.
• Thicker 0.04 in blade: At 0.04 in thickness each blade is more rigid and durable than many thin replacements, improving control during heavy cuts.
• Bulk pack of 25: The package gives a long supply for repeated jobs so users can keep spares on hand without frequent reordering.

Who It's For

The blades suit homeowners, landscapers and contractors who frequently cut wood, composite material or wood with embedded nails and want fewer blade changes during a job. They are good for outdoor garden trimming, demolition tasks and cutting PVC pipe in mixed project work.

Users who need the finest finish for cabinetry or detailed joinery should look to finer-tooth specialty blades instead, since the 4/6 TPI pattern is optimized for speed and rough trimming rather than smooth finish work.

Pros & Cons

Pros

• Durable bi-metal construction with 8% cobalt provides longer life than standard blades.
• Non-stick coating reduces friction and keeps cutting speed steadier on extended cuts.
• Thicker 0.04 in material improves rigidity and control when plunging into nailed or frozen wood.
• Pack of 25 offers good value for recurring jobs and reduces downtime replacing blades.

Cons

• The 4/6 TPI tooth count is not intended for fine finish work and can leave a rougher cut on finish-grade lumber.
