Bandsaw blades that keep fabrication shops cutting
Fabrication shops live on their bandsaw. This page matches Bahco and Morse bi-metal and carbide blades to the daily mix of solids, box, tube and angle, each welded to your machine's loop length in the UK.
When the bandsaw stops, so does the shop. Steel fabricators, structural steelwork contractors and general engineering job shops all depend on one machine to feed everything downstream. The work it faces changes hour by hour: solid bar in the morning, box section and angle after lunch, a casting or a stainless offcut before the end of the day.
Bi-metal blades carry that mix. A high speed steel tooth edge welded to a flexible alloy steel backing keeps the teeth hard at cutting temperature while the band flexes around the wheels, cut after cut. Choose the right pitch for the section and a good bi-metal band covers the daily run of solids, tubes and profiles. When hard or abrasive sections start slowing the saw down, carbide-tipped blades step in.

Why bi-metal leads in fabrication
Bi-metal blades weld a high speed steel tooth edge, commonly M42 or M51, onto a fatigue-resistant alloy backing. The edge stays hard at cutting temperature while the backing flexes around the wheels without cracking, which is exactly what a saw running all day demands. That combination cuts everything from aluminium to stainless and tool steels, so one blade family covers the daily mix of solids, box, tube and angle. It is why bi-metal is the default in fabrication and engineering workshops.
Carbide-tipped blades carry tungsten carbide tips on an alloy backing (some further coated) and those tips stay hard far beyond HSS temperatures. Step across when the work stops a bi-metal blade or wears it out quickly: titanium, nickel-based high-temperature alloys, hardened and abrasive tool steels, high-silicon aluminium and demanding foundry work. In a fabrication shop that usually means the awkward jobs, large or difficult sections and castings that dull a standard blade quickly. For everything else, stay on bi-metal and spend the difference on the right pitch.
On the saw table
The workpieces this industry actually feeds through a band, and what each asks of the blade.

Box section and angle
Hollow sections and angle are interrupted cuts: the teeth enter and leave the material at every wall, which is what strips teeth off the wrong blade. A structural pitch on a bi-metal band, like the Sandflex Top Fabricator, is designed for exactly this duty, including the mitre cuts that connect a steel frame. Match the pitch to wall thickness rather than overall section size and the blade lasts.

Solid bar work
Solid bar keeps the whole tooth line in the cut, so the blade needs enough gullet to clear chips and enough beam strength to cut straight. This is where an M42 bi-metal band such as the Morse M42 earns its keep on everything from mild steel to alloy steel. If the same saw sees stainless bar, keep feed pressure positive: stainless work hardens under a rubbing tooth and punishes hesitation.

Castings and hard sections
Castings and hardened or abrasive sections are where a fabrication shop's bi-metal habit gets expensive: the blade cuts, but slower every hour, until the saw becomes the bottleneck. Hardened or abrasive cast iron and tool steel grades, along with high-temperature alloys, sit squarely in carbide territory. A trimetal blade like the Easy-Cut Xtreme EZX keeps carbide life on the difficult work without giving up the general purpose range the rest of the week demands.
