Pros/Cons of brad-point and twist drill bits
I have sorted through my drill bits and wondered about the differences
between brad and twist drill bits. I mostly drill holes in wood, much less so in metal or plastics. Are both HSS? Are all bits typically Made in China? |

Are all bits typically Made in China? Different purposes. Brad-point drills are great for minimizing tearout in face grain. They're also easier to locate precisely due to the center spur. They can both be HSS, high carbon steel, carbide-tipped, or whatever other material you want. They can be made wherever. Lee Valley has very nice Made in USA twist drills in HSS. Their HSS brad-points start out as these twist drills, then LV grinds a spur and lips on them. Chris |

Are both HSS? Brad point = wood. Twist = Other than wood; however, bits for plastic are plastic specific. Are all bits typically Made in China? The cheap crap is most likely from China. If you want Fuller, both brad and twist, Jamestown Distributors has them. Lew |
