Keep the bit in alignment. Binding generates heat much more quickly than the cutting process itself. Cool the bits while they're not being used. A fan across them would do well, or lay them on a damp rag. Keep the bits sharp. Dull bits create more heat (in the bit and in the operator).See all results for this question
How to drill holes in 3/8" thick steel plates? - Home common steel plate thickness Hole drilling
Jul 07, 2019 · 8 Answers8. Active Oldest Votes. 28. 3/8" mild (hot-rolled) steel isn't difficult to drill, but any bit will fail if you get it hot enough to melt the cutting edge. Each hole should take no more than a minute. Use a sequence of sizes (1/8", 1/4", 3/8").
