Clean­ing and sur­face prepa­ra­tion in re­stricted ar­eas

DEMM Engineering & Manufacturing - - PRODUCT WATCH -

Most engi­neer­ing sup­ply stores will have some small stemmed wire brushes, usu­ally called the end brushes. How­ever not ev­ery­one may know what they are used for.

They come in dif­fer­ent shapes and sizes and were orig­i­nally de­signed for en­gine re­con­di­tion­ing jobs. But times have changed. There may not be as much re­con­di­tion­ing done as in the past and end brushes have be­come pop­u­lar in many ap­pli­ca­tions in­volv­ing work in re­stricted or hard-tore­ach ar­eas such as dies, tubes, en­gines, pis­tons etc.

When con­sid­er­ing the right brush for the ap­pli­ca­tion don’t n’t look just at the brush di­am­e­ter but also con­sider its full spec­i­fi­ca­tion. It is im­por­tant to re­alise that the wires will f lare out dur­ing brush ro­ta­tion. This means that the ef­fec­tive ive reach of the brush is in­creased. More im­por­tantly re­mem­berer to first insert the brush into a hole be­fore switch­ing the power tool on!

Some brushes have been de­signed to work at very high speeds and can there­fore be used on air pow­ered tools and die grinders. Al­ways check the max­i­mum speed of the tool and of the brush be­fore be­gin­ning a job.

Fi­nally, as with most things not all the end brushes are cre­ated equal and you get what you pay for. So ask your lo­cal al engi­neer­ing sup­plies store for ad­vice.
