The Mastercraft Titanium-Coated Drill Bit Set is perfect for home projects and DIY applications. With a wide variety of sizes, from 1/16" to 1/2" bits, these drill bits are titanium nitride-coated, which means less friction and cooler running. The 135° split point on 1/8" and larger stars reduces bit walking. This drill bit set for metal and wood comes with a handy heavy-duty case and tray to keep your bits organized.
