Reciprocating blades 5 Pack (L) 305mm – (W) 25mm – Thickness 1.3mm – 18TPI Metal

Description

What these 18 TPI metal blades are for

These Morse reciprocating saw blades come in a 5 pack and are 305mm (12″) long, 25mm (1″) wide and 1.3mm thick, with 18 teeth per inch. They are listed for metal cutting.

18 TPI is a fine pitch, with teeth roughly 1.4mm apart. More teeth in contact means a smoother cut on thin and medium walls, so these blades suit steel and copper tube, electrical conduit, box section, thin angle, strut channel and light sheet. On thick solid bar the small gullets fill up, so a coarser 14 TPI blade will cut faster there.

The combination of 25mm width and a 1.3mm body gives a rigid blade that holds its line over the full 305mm length. That is useful when reaching through larger pipes or cutting out old metalwork where accuracy and control matter.

How to check this is the right blade

Make sure the blade you are replacing is 305mm long and 25mm wide, and that a caliper reads 1.3mm on the body. Count the teeth over one inch: there should be 18. For tips on measuring blades and choosing a pitch, see how are bandsaw blades measured and which TPI do I need.

Frequently asked questions

Is 18 TPI or 14 TPI better for pipe?

As a rule, keep at least three teeth in the material. Thin-wall pipe suits 18 TPI; thicker-wall pipe and solid sections cut faster with 14 TPI.

How do I stop the blade chattering on thin tube?

Keep the saw’s shoe pressed firmly against the work, start at a slower speed and let the blade do the cutting rather than forcing it.
