The more expensive of the two sets has reduced shank bits so that you could fit a 1/2″ drill bit in a 3/8″ drill chuck. The Triumph 29pc drill bit sets I would consider are models 090517 (~$77-100), and 090829 (~$115), but only if I could catch them on sale. Then I’d probably spend an extra $200 on other tools I only realized I needed after searching for “just a couple” of additional items to help make the most of the shipping fee. With a $50-$75 budget, I’d go with that $60.30 29-piece Norseman bright finish HSS 118° point drill bit set from Harry Epstein’s. If you want shorter bits, then you’ll want to look at mechanic’s or even screw machine lengths. Oh, and you’ll want Jobber’s length twist bits.

(They also have some sweet email registration perks). Our friends over at Carbide Processors have a nice selection of Triumph sets, and occasionally offer coupons. I only have a couple of Norseman bits in my drawer, but I’ve been pleased with their performance.

If you want to go the quick and easy route, their 29pc Norseman bright finish HSS drill bit set is just $60.30, plus shipping. Harry Epstein is a good source of Norseman bits. One can save a lot of money off list prices by doing so. That’s not China, but also not USA.įor Triumph, Cleveland, Champion, Precision Twist, and other brand-name drilling, tapping, and cutting tool sets, I often look to Enco and MSC’s deals flyers. I just checked, and my set of black oxide screw-machine-length Precision #1-#60 wire gauge drill bits were made in Brazil. If you’ll primary work with steel materials, Triumph and other brands offer general purpose black oxide-finished bits.
The bright finish HSS (high speed steel) drill bits with 118° points should work great in wood, plastic, and softer non-ferrous metal materials, and okay in steel (but not stainless steel or hardened) materials.
According to that guide, their ThunderBit TiN-coated bits work best in every category. Triumph’s latest catalog ( PDF) has a handy drill bit selection guide on page 6. I mainly work with wood, plastic, and aluminum, and so for my “mega set” of 115 drill bits I went with Triumph HSS bits. I bought a small Triumph Trinado bit set with 135° split point tips before realizing that the black oxide and bronze coatings makes the bits best suited for use in iron, steel, and tough steel products.
