Helicoiling


the ug man

Recommended Posts

heres what you will need for helicoiling:

a drill that is the correct tapping size for a m5 wire insert tap

1 m5 wire insert spiral flute tap

5+ m5 helicoils

1 m5 helicoiling tool

a small set square

but doin it yourself is one hell of a job, im an apprentis at a local engineering firm where i live, and ive had an old trials frame scrapped cos the helicoil tool snapped in my frame, be carefull to make sure that you drill the tapping hole straight, and tapp the hole straight too, you can check the angles with the set square.

ill find out the drill size for you asap if you need i can write a guide for you too.

Hope this helps

Cheers

thanks so that will bring it down to a m5 and whats the cost going be iff u now

thanks for the info it will help a lot (Y)

The drilled hole needs to be 5.2mm for m5 (5.173-5.333 tolerance) if the hole is too big it wont work, you may need a keysert solid type insert.

At wti fasteners they supply the kits with the correct size drill bit, tap, 10 inserts, tang break tool £22
