Connector bolt jig

[Grifta75]

Hi folks,
I'm looking into manufacturing in MDF and the plan would be to assemble the product in the customers houses. What I'm looking for is a jig for drilling connector bolts into MDF for 90 degree joints.
Does anyone known of an accurate jig that I could use?
Also, would this be your choice of jointing technique for MDF?

Thanks in advance

I would check out the Lamello range of fittings. They look to have various products that will meet your criteria.
