What to look for in blades and abrasives
Tooth count (saw blades)
Fewer teeth (24T) cut fast and rough for framing; more teeth (40-60T) cut slow and smooth for finish work and sheet goods. Most people own one of each.
Arbor and disc size
Match the centre hole to your tool — a blade or disc that doesn't fit the spindle is no use. Check the size stamped on your saw or grinder before you buy.
Grit (abrasives)
Low grit (40-80) strips fast and leaves scratches; high grit (180-240) finishes smooth. Work up through the grits rather than jumping straight to fine.
The right disc for the job
Cutting discs are thin for slicing metal; grinding discs thick for taking material off; flap discs blend the two. Never grind with a cutting disc — it can shatter.
