Best 14/18 TPI Reciprocating Saw Blades for Metal Cutting
A 14/18 TPI reciprocating saw blade is a variable-tooth blade intended for metal cutting, with a tooth pattern that can balance cutting progress and a smoother finish. The best choice depends on blade length, pack size, and the materials you plan to cut. The 6-inch Cylrod and Diablo options suit buyers seeking shorter blades; the 9-inch Cylrod, BATHTOI, and EZARC options are better for buyers who want extra reach. The comparison below summarizes the listed differences.
| Product | Length | Pack | Best suited for |
|---|---|---|---|
| Cylrod M42 Cobalt | 6 inches | 25 | Short-blade metal cutting |
| Cylrod 9-Inch M42 Cobalt | 9 inches | 25 | Longer reach and metal work |
| BATHTOI Dual Tooth | 9 inches | 25 | Medium metal and listed demolition uses |
| EZARC Bi-Metal | 9 inches | 25 | Steel demolition and medium metal |
| Diablo Steel Demon | 6 inches | 25 | Short blades for medium metal |
Cylrod 6-Inch M42 Cobalt Blades
This 25-pack of 6-inch blades is made from bi-metal steel with 8% cobalt, according to the product description. It has a 14/18 TPI tooth pattern and a half-inch shank described as compatible with reciprocating saws from major manufacturers. The listing names automotive dismantling and metal cutting as intended uses.
Best for: Buyers who want shorter blades for metal work and value a larger pack. The product description says to reduce cutting speed for harder materials and increase it for softer materials, making feed and speed relevant to performance.
Limitation: The 6-inch length offers less reach than the 9-inch choices in this comparison. Choose another option if a longer blade is needed for the task.
Cylrod 9-Inch M42 Cobalt Blades
This 25-pack combines a 9-inch blade length with a 14/18 TPI pattern and M42 bi-metal construction containing 8% cobalt. The listing describes the teeth as designed for fine, clean cuts and identifies automotive dismantling and metal cutting as uses. It also states that the blades are intended to replace blades used with several major saw brands.
Best for: Buyers who want a longer blade than the 6-inch options and a 25-piece supply for recurring metal-cutting work. The longer format may be a practical choice when the cut requires more reach.
Limitation: The listing does not specify a metal thickness range. If thickness is a deciding factor, compare the workpiece with a product that provides a stated range.
BATHTOI 9-Inch Dual-Tooth Blades
BATHTOI’s 25-pack uses bi-metal steel with 8% cobalt and a non-stick coating, according to its listing. The 9-inch blades are described as suitable for medium steel and metals measuring 1/16 to 5/16 inch thick. Listed applications also include auto dismantling, fire rescue, construction, demolition, and PVC pipe cutting.
Best for: Buyers whose work matches the listed medium-metal thickness range and who want a product with several stated application areas. The product description also calls out a dual-tooth design.
Limitation: The stated metal range is specific. Avoid assuming these blades are appropriate for metal outside 1/16 to 5/16 inch without checking the task and blade requirements.
EZARC 9-Inch M42 Bi-Metal Blades
This EZARC 25-pack features 9-inch M42 bi-metal blades with 8% cobalt and a variable 14+18 TPI pattern. The listing highlights small gullets and a tooth design intended for steel demolition and metal cutting. It gives a medium-metal thickness range of 1/16 to 5/16 inch and claims up to twice the life of standard blades; that is a manufacturer claim, not an independent comparison.
Best for: Buyers focused on steel demolition who want a 9-inch blade and a clearly stated metal thickness range. The tooth and gullet details make this a useful option to compare for metal applications.
Limitation: The stated range is for medium metal. Choose based on the material and thickness rather than assuming the blade suits every demolition cut.
Diablo Steel Demon 6-Inch Blades
The listed Diablo Steel Demon pack contains 25 bi-metal blades measuring 6 inches, with a 14/18 TPI pattern. The product name identifies them for auto dismantling and medium metal with a stated thickness of 1/16 to 5/16 inch.
Best for: Buyers looking for a 6-inch format with a clearly stated medium-metal thickness range. It is a shorter alternative to the 9-inch blades in this group.
Limitation: The available product information is less detailed than the descriptions for several other options. Check the listing for any additional specifications needed before choosing.
Buying Guide: How To Choose A 14/18 TPI Blade
What does 14/18 TPI mean?
TPI means teeth per inch. A 14/18 TPI label indicates a variable tooth pattern rather than a single fixed count. For these products, the listings position that pattern for metal cutting. Match the blade to the material and workpiece thickness; tooth count alone does not establish suitability for every cut.
Should you choose a 6-inch or 9-inch blade?
Compare blade length with the reach and access your cut requires. The 6-inch Cylrod and Diablo products are the shorter options here. The 9-inch products offer additional blade length, but a longer blade is not automatically better for every task. Confirm that the blade length suits the saw and work setup.
Which material details matter most?
Look for construction and application information, including bi-metal composition, cobalt content, and any stated thickness range. BATHTOI, EZARC, and Diablo list a medium-metal range of 1/16 to 5/16 inch. The Cylrod 9-inch listing does not provide a thickness range in the supplied details. Do not infer a range where none is stated.
How many blades should you buy?
All five products are listed as 25-packs. A larger pack can suit frequent cutting or a work area where blades are replaced regularly. For occasional jobs, consider whether you need that quantity and whether the product’s specifications fit the material you will cut.
Will these fit your reciprocating saw?
The Cylrod listings describe a half-inch shank and broad compatibility, while other product descriptions also refer to reciprocating saws. Verify shank fit and the tool manufacturer’s requirements before purchase rather than relying only on brand-name replacement language.
