I have 2 holes that should be 17/32 on one end, 5/8 on the opposite end, hole is in 1/4" plate. What angle would this be? Can I buy a reamer that will do this? I've drilled the 2 holes 1/2" to start
No formula for me, I drew it in AutoCAD.so what is the formula?
Θ = arctan((d1 -d2)/2t); Θ = half angle, d1 & d2 are entrance and exit hole diameters, t = thickness.so what is the formula?
