Application
Variable-pitch bimetal bandsaw blades in narrower widths are a popular choice for cutting metal tube, thin-wall section, and mixed bundles where vibration control is essential for blade life and operator comfort.
Bandsaw Blade Width: 1/2"
At 1/2" wide, this is the most common general-purpose bandsaw blade width. It tracks reliably for straight ripping, resawing, and gentle curves on mid-size floor-standing machines, and is the default choice for most wood and light metal bandsaw blade work.
TPI: 10–14 TPI (variable pitch)
Variable pitch — very low vibration on thin steel section, ERW tube, and sheet.
Keep at least 3 teeth in contact with the workpiece at all times for efficient cutting and to avoid stripping tooth tips. For thin-wall or variable-section material, variable-pitch bandsaw blades reduce harmonic vibration and extend bandsaw blade life.
Bandsaw Blade Length: 670mm
A 670mm bandsaw blade fits compact benchtop bandsaws. These smaller machines are common in hobbyist workshops and light trade use, where work-piece size is limited but the machine is portable and cost-effective.
If your saw requires a slightly different bandsaw blade length, enter your exact measurement in our configurator — we cut bandsaw blades to any length within our range. The loop length is always measured with the bandsaw blade ends joined as they run on the machine.
Choosing a 670mm 1/2" 10-14 TPI bimetal blade
This 670mm bimetal bandsaw blade is 1/2" (about 12.7mm) wide with a 10-14 TPI variable pitch. It is a versatile choice for a compact metal-cutting bandsaw, handling everything from solid bar to medium-wall tube and angle without changing blades.
A 10-14 variable pitch mixes tooth spacings of roughly 1.8mm to 2.5mm. The varied spacing cuts down vibration and noise, and suits a wide range of section sizes. As a guide, keep at least three teeth in contact with the material, so this blade is most comfortable on walls and sections from around 6mm upwards; for thin tube and sheet a finer pitch such as 14-18 or 24 TPI is a better match.
Being bimetal, the blade has a high-speed steel cutting edge welded to a flexible steel back. The hard edge holds up to the heat of cutting mild steel, stainless and non-ferrous metals, while the flexible back copes with the constant bending a short 670mm blade sees on small wheels. At 1/2" wide it is best for straight cuts, with only gentle curves possible.
Frequently Asked Questions
What can a 670mm 10-14 TPI bimetal blade cut?
It suits general metal cutting on a compact bandsaw: mild steel, stainless steel, aluminium, brass and copper in bar, tube and profile, especially medium sections.
How do I know 670mm is the right length?
Measure your old blade end to end or check your machine plate or manual. A short blade has little tension adjustment, so it needs to be the correct length. Our How to Measure guide explains each method.
Is variable pitch better than a single TPI?
For mixed work, usually yes. A 10-14 blade runs more smoothly across different section sizes, whereas a single pitch such as 14 TPI is better when you cut the same material every day.
