This guide is for trade professionals and serious DIYers needing reliable metal cutting. The Eclipse Plus 30 Bimetal hacksaw blades offer a durable and precise cutting solution, especially for tougher materials like alloy and stainless steel. A key benefit is their longevity and aggressive cutting action. However, they are sold in multi-packs, which may be more than a casual user needs.

TPI stands for Teeth Per Inch. A higher TPI (like 32 TPI) means more teeth per inch, resulting in a finer cut suitable for thinner materials. A lower TPI (like 18 TPI) means fewer teeth per inch, allowing for faster cutting of thicker materials.
For general stainless steel cutting, the 24 TPI blade offers a good balance. For very thin stainless steel sheets, the 32 TPI might provide a cleaner finish, while for thicker stainless steel sections, the 18 TPI could be more effective for faster removal.
Insert the blade into the hacksaw frame with the teeth pointing forward (away from the handle). Ensure the blade is securely tensioned by tightening the frame's adjustment screw. The blade should be taut, like a drum skin.
No, these are bimetal blades specifically designed for cutting metal. Using them on wood will dull the teeth rapidly and will not produce a clean cut.
Bimetal construction combines a hard, high-speed steel cutting edge with a flexible alloy steel back. This makes the blade more durable, resistant to shattering, and capable of withstanding higher cutting temperatures, leading to a longer service life.
The lifespan of a blade depends heavily on the material being cut, the TPI used, and proper technique. However, due to their bimetal construction and high-speed steel edge, these blades are designed for extended use and professional applications, lasting significantly longer than carbon steel blades.
Ensure the blade is correctly tensioned in the hacksaw frame and that you are not applying excessive side-force or twisting the blade. Check for blockages in the material being cut.
Verify that the correct TPI is being used for the material. For thicker metals, a lower TPI (e.g., 18 TPI) is generally faster. Ensure the blade teeth are not clogged with material.
Check that the blade teeth are facing the correct direction (forward). Ensure the material is securely clamped and that you are applying steady, even pressure on the forward stroke.
Consider using a higher TPI blade (e.g., 24 or 32 TPI) for a finer finish. Ensure the blade is properly tensioned and that the workpiece is stable.
