9 in 14/18 TPI Bi-Metal Reciprocating Saw Blades 25 Pack - Thick

In this review the 9 in 14/18 TPI Bi-Metal Reciprocating Saw Blades 25 pack is evaluated for garage mechanics, metal recyclers, and DIYers who need a mix of metal and wood cutting performance. The bottom line: this set stands out for its 0.042 in ultra-thick construction and a Perma-Shield non-stick coating that reduce heat and blade jumping during cuts, delivering consistent performance on medium metals from 1/16 to 5/16 in. It is a practical option when quantity, thickness, and a universal fit are the primary purchasing criteria.

Key Features

• 25-piece pack: Provides a large supply of replacement blades so projects can continue without frequent reordering.
• Bi-metal construction: The unique Bi-Metal steel formulation is designed for combined durability and cutting edge life on steel and mixed materials.
• 0.042 in thickness: Extra-thick body reduces blade flex and jumping for more accurate, labor-saving cuts in medium metals and wood.
• 14/18 TPI tooth pattern: The mixed tooth pitch balances material removal and finish, making it suitable for 1/16 to 5/16 in medium metal cutting tasks.
• Perma-Shield coating: A non-stick coating helps reduce heat and sticking, which can prolong blade life and improve cutting consistency.
• Universal fit: Works with most reciprocating saw handles so it can be used across different tool brands in a typical shop.

Who It's For

This set is aimed at automotive dismantlers, metalworkers, and serious DIYers who need a high-count pack of blades able to tackle medium-thickness steel, nail-embedded wood, and general demolition tasks. The mixed 14/18 TPI and extra thick construction suit jobs where stability and durability are more important than fine finish.

Those who should look elsewhere include tradespeople who require specialized blades for very hard alloys or precision finish cutting, and users who operate at consistently low saw speeds and expect extremely long edge life, since some users reported faster dulling under those conditions.

Pros & Cons

Pros

• Thick 0.042 in blades reduce flex and improve cutting control on medium metals.
• Large 25-pack offers value and convenience for repeated or large jobs.
• Perma-Shield coating and Bi-Metal steel help manage heat and extend useful life versus plain carbon blades.
• Universal fit makes the blades compatible with most reciprocating saws in a workshop.

Cons

• Some users have reported durability issues under heavy or low-speed use, with blades dulling or bending sooner than expected.
• The mixed 14/18 TPI is versatile but not optimized for ultra-fine finish cutting or very hard exotic metals.
