<div> <font size="3">A drill guide as you describe is a good idea. I always use a guide like that whenever I use a tap. If you get a tap started crooked you will never get it straightened out. I like to use a solid block of aluminum but I have also used square tubing. Same principal applies when hand drilling.<br>

<div dir="ltr">What is the best way to drill a perpendicular hole for an insert?
<div>I'm using a 7/16-20 time sert. I need to drill a perpendicular hole in the captive nut. The dril I need to use is 29/64. Should I start with drilling smaller diameter holes and then end up with the 29/26? </div>
<div>Im thinking of drilling a perpendicular hole in a piece of wood in my drill press and then using that as a guide.</div>
<div>Any recommendations please. The last time I used an insert, the hole wasn't perpendicular. </div>
