3/8" slot

[quakebo]

I am going to use this slot cutting bit http://www.wealdentool.com/acatalog/Online_Catalogue_Groover_134.html (t5420) so would I need a 3/8" guide bearing to make a slot 3/8" deep?  If not what size guide bearing for 3/8" slot depth.

No to the 3/8" bearing. If you want  3/8" deep that is 9.525 mm. They list two bearings that are more or less than that. I don't see anything that is precisely what you want, but I may not have looked super hard:


TB870 - 9mm Depth - 22mm diam
9.525mm Depth -- What you want
TB760 - 10mm depth - 20mm diam

thanks for the reply's but I can not find one with a 1/4" hole to fit it onto the arbor.
I can not find one at 9.525mm so would 10mm do?

it's best to buy them as a set so they are machined to fit together. most have a 5/16ths hole.

thanks for that but I would like to buy from the uk.  and also it is the bearing I am looking for.

I'd guess that it's work. I don't know how accurate that site is, but when looking at the Groover, they have a link to the Guide Bearings. If the chart is right, then the TB760 - 10mm  is the one you want. But, you'd want to double check to verify they work together. Maybe email them and verify with them, since they should know.

ok thank you.  I have been emailing them and they told me witch bits to get for what I want so all sorted now.

which sizes or parts did you order (for posterities sake) it will help out someone else in the future.

[quakebo]

I went with theses bit witch will give me two slot's 10mm deep and 1.5mm and 2mm wide.
