<div dir="ltr">I searched my not inconsiderable archives for an answer, but have come up empty-handed. I am using 1/0 Denro blued tuning pins in a new multi-lam Maple pinblock, and need to order the drill bit. I'd like to double-drill - makes sense. The Pianotek catalog recommends, in effect, a drill bit .016" to .021" under the diameter of a 2/0 pin in a multi-lam pinblock. Following that logic, I could use the .250" on the first pass, and the .261" (.015" under) or .257" (.019" under) drill bit on the second pass. Also, I like the idea of the brad-points, but also like the idea of the other ones, which are "slow spiral." Any recommendations?<br>
