What is the difference between a Hard Back and a Flex Back bandsaw blade?

A Flex Back blade features a hardened tooth tip but a flexible, tempered backing material designed to withstand high flexing stress over smaller wheels. A Hard Back blade features a fully hardened backing steel, which provides significantly higher structural rigidity and allows for heavier feed pressures without the blade twisting or bowing.

Can M.K. Morse Hard Back blades cut metals?

Yes, because the back and teeth are both hardened, these carbon steel blades are excellent for slicing through soft, non-ferrous metals such as aluminum, brass, copper, and bronze, provided your machinery is set to low-speed metal cutting parameters (SFPM).

Why does my hard back blade keep breaking prematurely?

Hard back blades are highly rigid and less tolerant of tight bending stresses. Premature breakage is usually caused by running the blade on wheels that are too small in diameter (under 14 to 16 inches) or over-tensioning the machine beyond the manufacturer's recommendations.

What tooth pitch (TPI) should I choose for cutting thick aluminum plate?

For thick, solid aluminum or dense hardwoods, choose a coarser tooth pitch (such as 3 TPI or 4 TPI). This creates large gullets that efficiently clear heavy chips out of the cut zone, preventing the blade from binding or stalling.

Quiksilver Carbon Hard Back Blades

Upgrade your heavy-feed production operations with custom-welded M.K. Morse Carbon Hard Back bandsaw blades. Engineered with both a hardened tooth tip and a hardened back, these premium carbon-steel loops provide the exceptional beam strength required to eliminate bowing and backing deflection under immense pressure. This rigidity makes them the definitive choice for high-speed, straight-line tracking in hardwoods, dense multi-wall plastics, bone, and non-ferrous metals like aluminum and brass. Available custom-cut to your exact machine specifications, Morse hard back bands deliver clean, uniform cuts while significantly maximizing tool life over standard flexible blades.

Blade Features:

Manufactured from a single piece of high carbon steel with individually hardened tooth tips
Low cost-per-blade/low cost-per-cut in wood & similar materials
In metals; low cost-per-blade/higher cost-per-cut than bi-metal
Stiffer than hard edge flex (HEF) bandsaw blades due to a hardened & tempered backer
Straighter cut with heavier feed pressure than carbon HEF
Good on easy-to-machine metals and other easy-to-cut materials
Not recommended for blade speeds exceeding 4000 sfm

Applications:

Low alloy, easy-to-machine ferrous metals
Non-ferrous metals: Brass/copper, Bronze, Aluminum, Lead
Wood
Plastic
Cork
Composition board
Plywood
