The speed on most newer drill presses is too high for bits over 1/2”. My Delta 12 speed turns from 3000 - 250 RPMs. I recently put a reduction kit on it that reduced speed by 75%. Now, top speed is 750 RPMs, which is plenty for small bits, and 62.5 RPMs, which is perfect for larger bits. Too much speed is a killer for larger bits.
