/diy/ - Do It Yourself

If your chips don't look like pic related, you're not using enough pressure for optimal cutting. It's not as big a deal with mild steel, but if you try light pressure on stainless or other work-hardening steels, you'll sit and spin, and burn up the bit's tip. Even with a fresh 135 degree split point, it takes a lot of pressure unless you're drilling tiny holes. Standard points are right out above maybe 3/16" or so unless you can brace yourself to apply a hundred or so pounds of feed pressure, and that won't get you very large without multiple steps. There's a reason manufactured holes in steel are cut by CNC machine when possible, and by drill press if possible before bringing out hand drills.

>>1351104 is right. Using the proper feed pressure actually increases the life of bits over using excessively light pressure.
