ASK THE EXPERT: When should you change your cutting disc?

[Music]

hi we have another question here on ask

the expert and today's question is when

should you change your cutting disc okay

so there's three main reasons why you

need to change your cutting disc the

first one would be how warm the disc is

second would be the validity date of the

disc and last of all does the disc

contain any damage at all so uh the

first one uh disc size okay so you see

here I have a discount I wore down

earlier uh to quite a small diameter it

started out like this and now we have it

like this now there is actually no issue

where you can still put this on a

machine and cut with it it will still

cut but the issue with having such a

small dime with the disc is that the

penetration depth is really small so you

can only cut really really thin material

with this also the peripheral speed of

this disc will be much much lower than

it is when it's in a a bigger size like

this and therefore it would be very slow

uh at cutting so therefore quite

inefficient so best to change that out

to a new disc before you get as smaller

diameter as that now the second reason I

said was a validity date now when we

manufacture disks such as this on the

metal center ring we always stamp the

date of validity on there these discs

are have a validity of three years so

you can see on this disk we have a year

2025 which it will expire and we also

have a month on here as well which is

v07 and that stands for in July of 2025

this disc has expired and therefore

should not be used and last of all

damage so before you use a disc on an

angle grinder even when it's already

mounted on the angle grinder before you

start the machine and start your cutting

always check the disk for any damage any

cracks anything wrong with the periphery

of the disc before you use it if you see

any form of damage take the disc off

throw it in and use a new one it's

really as simple as that okay hope that

answers your questions any more
