Hymnorq Metric M3 x 0.5 Black TiAIN Finish HSS Co M35 Drill and Tap Combination Bit with 1/4” Hex Shank and Self Centering Split Point for Aluminum Iron and Stainless Steel

Q: Will these drill & tap 1/4" thick cast iron?

Thanks for your question. The max depth of drilling and tapping for this product is 4mm. 1/4" equals to 6.35mm. So it's too thick. This kind of combination drill & tap bits are only suitable for thin metal sheets, no matter what the brand is. In addition, it's suggested that you use M2 HSS bits or M35 cobalt bits to drill cast iron.

Q: What’s the three count example 1/4 what 20 - 28 kinda important

Thanks for your question. Take BSW 1/4-20 as an example. "BSW" means British Standard Whitworth screw thread series. "1/4" is the inch diameter of the bit. "20" means 20 threads per inch. Try to search the keyword "BSW size" on Google or Bing and you'll learn more. Actually, we don't quite understand your question. If the answer isn't what you need, please reply to us.
