The Drillco 500EW29 is a 29-piece fractional cobalt jobber drill bit set covering 1/16" to 1/2" in 1/64" increments — built for professionals who need reliable performance in hard, tough materials. Manufactured from M42 cobalt high speed steel, these bits run at speeds up to 30% faster than standard HSS drills without losing their edge. The 135° self-centering split point starts on contact, eliminating the need for a center punch and reducing bit walking on curved or uneven surfaces. Heavy-duty construction meets Type J aircraft specifications, making this set the right choice for stainless steel, titanium, hardened alloys, and high-tensile-strength applications where lesser bits burn out or break. A bronze oxide finish reduces friction and heat buildup, extending cutting life between sharpenings. Every bit stores in the included Drill Pal case with labeled slots for fast size identification and organized transport. Made in the USA by Drillco, a Walter Surface Technologies brand with decades of precision tooling experience.
