Reciprocating blades 5 Pack (L) 229mm – (W) 20mm – Thickness 0.9mm – 18TPI Metal

Description

What this blade is for

This 5 pack holds Morse reciprocating saw blades 229mm (9″) long, 20mm wide and 0.9mm thick, with a fine 18 TPI tooth pitch. They are listed for metal.

The fine 18 TPI pitch, with teeth about 1.4mm apart, is designed for thin material: sheet steel, conduit, trunking, ducting and thin-wall tube. More teeth in contact means less snatching and a cleaner edge on thin metal. For thicker solid sections, a 14 TPI blade clears swarf faster.

The 229mm length gives the extra reach to get across wider ducting, larger-diameter thin-wall pipe or into recessed areas. As it is longer and fairly thin, keep the saw’s shoe firmly against the work to limit flex and vibration.

How to check this is the right blade

Check your old blade for the 229mm overall length and 20mm width, and count the teeth over one inch: there should be 18 fine, evenly spaced teeth. For the reasoning behind tooth choice, see our how blades are measured and which TPI do I need guides.

Frequently asked questions

What is an 18 TPI reciprocating blade used for?

It is used for thin metal, such as sheet, conduit, ducting and thin-wall tube, where a fine tooth pitch keeps enough teeth in the cut.

Does a longer blade cut faster?

Not by itself. A longer blade gives more reach, but cutting speed depends mainly on tooth pitch, stroke speed and the material.
