Yougfin Drill Bits, 29 Pieces High Speed Steel Drill Bit Set, Twist, 1/2 Inch Product Details ?Premium Material?: These Yougfin jobber drill bits are made of high speed steel, ensuring durability and resistance to friction and heat so you can drill continuously without the bits heating up. ?Efficient Design?: The split point design increases the cutting edge on the tip, while the 135 angled tip means more of the cutting edge touches the surface sooner. The twisted shank features grooves that bring metal shavings up and out of the hole as you drill. ?Wide Range of Sizes?: This assortment includes 29 sizes ranging from 1/16" to 1/2", indicated clearly on each bit for easy identification. Store them efficiently and securely in the included portable metal case. ?Versatile Application?: These drill bits are perfect for drilling wood, plastic, and some lightweight metal materials.
