Description
Procat reciprocating saw blade for metal is a replacement blade for reciprocating saws for cutting metal. The blades come in packs of three, and the models are 100 mm, 150 mm, 200 mm, 250 mm and 300 mm, all with a tooth pitch of 24 TPI.
24 TPI means 24 teeth per inch, which is a fine tooth pitch. When cutting metal, the tooth pitch must be fine enough that at least three teeth are in contact with the workpiece throughout the cut. If fewer teeth are in contact, a tooth catches on the edge of the material and chips. Fine teeth are therefore suitable for thin-walled material: sheet metal, pipes, profiles and bars.
The blade length is chosen according to the thickness of the workpiece and the job. 100 mm and 150 mm stay under control in tight spots and on short cuts, while 250 mm and 300 mm reach through the structure and cut a pipe or profile in place. The blade must extend beyond the workpiece over the whole stroke length so that the teeth do not come out of the cut at the end of the stroke.
The fixing shank of the blade is universal and fits the most common reciprocating saws, such as AEG, Bosch, DeWalt, Hitachi, Black&Decker, Makita, Metabo, Flex, Atlas Copco, Skil, Milwaukee and Sabre machines. The blade intended for cutting wood is the Procat reciprocating saw blade for wood, and for aerated concrete and brick blocks the Procat reciprocating saw blade for blocks.
Intended use and suitability:
A reciprocating saw cuts metal with a back-and-forth stroke in places a cutting disc or hacksaw cannot reach. The blade is chosen according to the wall thickness and the depth of the job.
- Plumbing: a 200–300 mm blade cuts water and drain pipes and conduit in place.
- Sheet metal work: 24 TPI teeth cut thin sheet and sheet metal without tearing the edge.
- Profiles and bars: cutting steel profiles, threaded rods and angle irons on site.
- Tight spots: a 100 mm and 150 mm blade shortens the reach of the tool and stays under control inside an enclosure or frame.
- Demolition and maintenance work: cutting brackets, screws and fixings when the part cannot be undone.
Package contents:
- 3 x reciprocating saw blade of the selected model (100 mm, 150 mm, 200 mm, 250 mm or 300 mm, 24 TPI)
Features:
- Five lengths: 100, 150, 200, 250 and 300 mm cover everything from tight spots to cuts that reach through the structure.
- 24 TPI fine teeth: keep several teeth in contact with a thin wall, so a tooth does not catch or chip.
- Universal fixing shank: fits the most common reciprocating saws, so the blade works whatever the brand of machine.
- Pack of three: replacement blades in the same pack, so work carries on when a blade wears out.
- Same tooth pitch in all lengths: the cut and working method stay the same when you change length.
Technical specifications:
- Models: 100 mm, 150 mm, 200 mm, 250 mm and 300 mm.
- Tooth pitch: 24 TPI (teeth per inch) on all models.
- Fixing shank: universal reciprocating saw shank.
- Material worked: metal: thin sheet, pipe, profile and bar.
- Pack size: 3 blades.
Procat reciprocating saw blade for metal instructions for use:
Choosing the blade: Choose a length that extends beyond the workpiece over the whole stroke length. Make sure at least three teeth are in contact with the wall of the workpiece; thin sheet metal and pipe need fine 24 TPI teeth.
Fitting: Stop the machine and remove the battery or plug. Push the blade shank all the way into the blade holder and check the lock by pulling on the blade.
Sawing: Clamp the workpiece in a vice or with a clamp; loose metal vibrates and catches on the blade. Rest the shoe of the machine against the workpiece before starting. Use a low stroke speed: metal is cut more slowly than wood, because a high speed heats up the teeth and blunts them. Let the blade advance without pressing. In thick material, lubricate the cutting point with cutting oil to keep the teeth cooler and extend the blade’s life. If the wall is thick, cut the pipe in several positions by turning it.
Maintenance: Let the blade cool before changing it. Remove metal chips and cutting oil from the blade after use and check the condition of the teeth. Store the blades dry in their original packaging or a case.
Warnings:
- Stop the machine and remove the battery or plug before changing the blade.
- The blade and the cut metal are hot straight after sawing; wear protective gloves.
- Wear safety glasses and ear defenders. Metal chips and a broken blade fly off.
- Clamp the workpiece. A loose pipe or profile vibrates, catches on the blade and is thrown.
- Keep the shoe of the machine against the workpiece throughout the cut; a machine held free kicks.
- Before cutting, make sure there is no pressure, flammable liquid or gas in the pipe and no live conductors at the job.
- The edge of cut metal is sharp and burred; handle it with protective gloves.
- Do not use a bent or cracked blade or one with chipped teeth.
- Keep the blades out of the reach of children.
Frequently asked questions (FAQ):
What lengths does the Procat reciprocating saw blade for metal cover? Five lengths in packs of three: 100, 150, 200, 250 and 300 mm, all 24 TPI.
What does 24 TPI mean? The tooth pitch: 24 teeth per inch. Fine teeth keep several teeth in contact with a thin wall, so a tooth does not catch or chip.
Why is metal sawn at a low stroke speed? A high speed heats up the teeth, so they lose their hardness and go blunt quickly.
Is it worth lubricating the cutting point? Yes, in thick material. Cutting oil keeps the teeth cooler and extends the life of the blade.
What length of blade for cutting a pipe? The blade must extend beyond the pipe over the whole stroke length, so a 250 mm or 300 mm blade is chosen for a large-diameter pipe.
Can a metal blade saw wood? Fine 24 TPI teeth clog with wood chips and advance slowly; for cutting wood, choose a blade intended for wood.
Why do the teeth chip when sawing thin sheet metal? The workpiece has been allowed to vibrate, or too few teeth have been in contact. Clamp the piece firmly and rest the shoe of the machine against the surface.
Recycling instructions:
Sort cardboard and plastic packaging into their own collections. A worn or broken reciprocating saw blade is metal and goes to metal collection or a recycling centre; wrap the sharp blade in cardboard before putting it in the bin. Metal chips from sawing belong in metal collection. Used cutting oil and oily cloths are hazardous waste and go to a hazardous waste collection point.
