Bi-Metal Bandsaw Blade Applications in the UAE

Bi-metal bandsaw blades are the standard tool for production sawing in UAE fabrication shops, steel stockholders and maintenance workshops. This page walks through the jobs TFI Co. M42 blades are used for, from hydraulic cylinders and bundled round bar to square tube, flat bar, aluminium block and stainless steel pipe, and explains how to choose the tooth pitch (TPI) for each one.

Where bi-metal blades are used

A bi-metal blade welds a strip of M42 high-speed steel onto a flexible spring-steel back. The back survives millions of flexing cycles around the wheels; the HSS teeth keep their edge at metal-cutting heat.

That is why most horizontal and vertical metal-cutting bandsaws in the region run bi-metal as standard. TFI Co. has supplied the UAE and GCC since 1965; these are the applications customers ask about most.

Which TPI for steel bar

TPI (teeth per inch) is the most important choice when ordering. Too few teeth in the cut and each takes too large a bite, causing vibration and stripped teeth. Too many and the gullets choke, so the blade rubs, overheats and wanders.

Size the pitch by the length of material actually in the cut, not the outside size. A flat bar on edge presents its width; laid flat, its thickness. The usual working guide:

Which TPI for steel round bar

Round bar is harder on the blade than square because the cut length changes continuously: few teeth engage at entry and exit, the full diameter through the centre. Variable pitch breaks up the vibration that constant pitch sets up.

• Choose the pitch for the full diameter using the table above.
• Clamp the bar firmly; any rotation in the vice snaps teeth at entry.
• Reduce feed slightly at entry and exit, where few teeth carry the load.

Cutting round bar in bundles

• Clamp the bundle tightly so bars cannot roll; loose or mixed-diameter bundles are a common cause of early tooth loss.
• Start from the pitch for a single bar, then go one step coarser (for example 6/10 to 5/8 TPI) so gullets carry chips across the full width.
• Use variable pitch to cope with repeated entry and exit as teeth cross from bar to bar.

Cutting tubes, profiles and flat bar bundles

Tube and pipe are thin-walled, so the danger is too coarse a pitch. Keep at least two, preferably three, teeth in the wall at all times and choose by wall thickness:

• Tube bundles and deep sections: step one pitch coarser so gullets carry chips across the work.
• Flat bar stacks: behave like a series of thin sections; clamp vertically as well as horizontally to stop layers chattering, and use variable pitch.
• Beams and channels: interrupted cuts through flanges and web favour a variable pitch such as 3/4 or 4/6 TPI with a strong tooth.

Aluminium blocks and stainless steel pipe

Cylinders and hard-surfaced work

Hydraulic cylinder rods are often chrome plated and induction hardened on the surface while the core stays relatively soft. The hard skin, and the switch from skin to core, is what chips teeth.

1. Clamp the rod firmly so it cannot turn.
2. Start at reduced feed until the teeth are through the surface layer.
3. Increase to normal feed in the soft core and keep it steady.

For heavy production of hardened rod, carbide-tipped blades are the usual industry answer; for occasional work, a heat-resistant HSS tooth with a special relief angle can be enough. Ask us to compare options.

Coolant in UAE workshops

Coolant removes heat, lubricates the tooth and flushes chips; without it, even the right blade loses its edge quickly. In UAE heat, water evaporates fast, so check concentration often.

Choosing the right blade from the M42 range

The M42 bi-metal range covers general mild steel, structural and stainless steel, and more difficult alloys, in the common widths for workshop and production bandsaws. Models, sizes and tooth hardness are in the M42 bi-metal bandsaw blade catalogue.

Unsure which model or pitch suits your work? Tell us the material, section size and machine model and we will recommend a specification.

This page details bi metal bandsaw blades applications in the UAE for cylinder cutting, circular solid rod bundles, square tubes, rectangular tubes, flat bar bundles, aluminium blocks, stainless steel pipes and many more metalworking tasks, helping procurement teams and fabrication workshops select the correct M42 tooth pitch and TPI for each material. Readers gain clear guidance on blade specification to achieve precise, efficient cuts while solving common selection problems that affect productivity and blade life in both metalworking and food-industry bandsaw operations. As Manufacturer of Steel Blades Since 1965, TFI Co. structures this practical catalogue content to support direct quotation and ordering enquiries across the UAE and GCC.
