Bonded grinding wheels for weld dressing and heavy stock removal. Shape, grade code and maximum safe RPM are stated on every listing.
Choosing the right one
Should I use a grinding wheel or a flap disc?
A bonded grinding wheel removes metal faster and holds an edge for heavy weld dressing. A flap disc grinds and finishes in one pass and leaves a better surface, so it saves a step when the part will be seen or coated. Heavy removal favours the wheel; blending and finishing favour the flap disc.
What is a Type 11 flaring cup wheel for?
A flaring cup wheel presents a wide flat face rather than an edge, which suits surface grinding, snagging and work on stone and concrete where you want an even contact area instead of a cutting edge.
What does the grade code mean?
A code such as A24R reads as grain, grit and hardness: A is aluminium oxide, 24 is the grit, and the letter is how firmly the bond holds the grain. A harder grade holds grain longer and suits softer material; a softer grade releases grain faster and stays sharp on hard material.
How do I know a wheel is safe to fit?
Check the maximum RPM marked on the wheel against the no-load speed on the grinder, and inspect the wheel for cracks before mounting. A wheel that has been dropped should not be used.
