DRILL BIT RPM CHART - Imperial Supplies

- When drilling hardwood floor boards for trailers, it is recommended that the RPM's and speed of feed is reduced. Reasoning for this is hardness of material and depth of hole being cut. - If using a 5/16" drill bit that will drill through 1-3/8" hardwood board, the recommended rate of speed is 1,500 RPM.

Recommendations for drilling 17-4 - Practical Machinist

I've been able to square up the block with carbide no problem but I'm having issues drilling. Feeds and speeds recommendations seem to be all over the place. I first tried HSS with too high a sfm and it quickly melted. Using a stub 5/16 carbide drill, I went with 60 sfm but only .001 chip load and it started getting ugly after a few holes.

Drilling 304 Stainless Steel - Practical Machinist

General wisdom on HSS in stainless is run at half the speed for steel (60-100ft/min). 500rpm for .500" diam gives you about 70ft/min. That would be 1000rpm for a 1/4" bit in steel. 500rpm for 1/4" in stainless. Start there, you might be able to bump up a tad, but watch the corners of your drill lips.

The problem is that many stainless steels – 304 and 316 in particular – can get harder and tougher to cut as you work if the cutting tools are improperly applied. This phenomenon, known as work hardening, occurs because of the heat generated if the incorrect speed and feed rates for drilling and tapping stainless steel are applied.

Cutting Speeds & RPM Calculations

A high speed steel "G" drill is being used prior to reaming a 3/8 hole on a piece of 1095 steel with a brinnel hardness of 300. Calculate the RPM setting to perform the drilling and reaming operations. Cutting Speed = 40 (fpm) Diameter of Cutter = 0.3701 (G drill) Half the speed for reaming would be = 432 / 2 = 216 RPM for reaming.
