RYOBI Introduces the Black Oxide Drill and Drive Kit (40-Piece). This 40-Piece Drill and Drive set is a great kit for projects including wood, metal, and plastic materials. The Black Oxide bits are constructed out of high-speed steel with a black oxide finish to offer superior durability. Another key detail of these bits is the 135° split point that prevents your bit from walking and ensures drilling on contact. This kit features bits containing a TORSION ZONE that is engineered to absorb the high torque and demand that comes with the use of an impact driver for 3X longer life. This kit contains a variety of the most commonly used 1" and 2" bits, nut drivers that have excellent holding power when using hex drive fasteners and a magnetic bit holder for increased convenience. Included in this set are Woodboring Spade Bits that provide up to 1" wood drilling capacity for a wide array of applications. The compact case adds effortless storage and mobility. This set includes (12) black oxide drill bits, (2) woodboring spade bit, (4) bradpoint drill bits, (14) 1" impact driver bit, (4) 2" impact driver bit, (3) impact nut drivers, (1) impact magnetic bit holder, and a clear front carrying case.
