Features:&nbsp;<br> <br> 29Pcs 135 degree twist drill bits includes: 1/16in, 5/64in, 3/32in, 7/64in, 1/8in, 9/64in, 5/32in, 11/64in, 3/16in, 13/64in, 7/32in, 15/64in, 1/4in, 17/64in, 9/32in, 19/64in, 5/16in, 21/64in, 11/32in, 23/64in, 3/8in, 25/64in, 13/32in, 27/64in, 7/16in, 29/64in, 15/32in, 31/64in, 1/2in.<br> <br> Premium material: crafted from industry-grade HSS high-speed steel, these drill bits are fully ground for enhanced durability and performance, providing superior hardness.<br> <br> Black and gold polished treatment: the black and gold polished finish enhances lubricity and creates small pockets on the tool's surface to hold coolant near the cutting edge.<br> <br> 135-degree design: the 135-degree tip and twist design allows for easier drilling into harder materials, reducing wear and tear compared to standard 118-degree bits. This ensures more efficient and precise hole drilling.<br> <br> Spiral fluted design: when run in a counterclockwise direction (right-hand cut), spiral fluted tools evacuate chips up and out of the cut to reduce clogging.&nbsp;<br> <br> Wide applications: the drill bits keep centered without a pilot hole. Ideal for drilling mild metal, steel and alloy, iron, cast iron, copper. These jobber drill bits have the rigidity and length for most applications of corded or cordless hand drills and drill presses.The plastic case is lighter in weight and easier to carry.<br> <br> Specification:&nbsp;<br> Product name: Twist Drill Bits Kit&nbsp;<br> Material: HSS High Speed Steel&nbsp;<br> Color: black gold&nbsp;&nbsp;<br> Sizes: 1/16in, 5/64in, 3/32in, 7/64in, 1/8in, 9/64in, 5/32in, 11/64in, 3/16in, 13/64in, 7/32in, 15/64in, 1/4in, 17/64in, 9/32in, 19/64in, 5/16in, 21/64in, 11/32in, 23/64in, 3/8in, 25/64in, 13/32in, 27/64in, 7/16in, 29/64in, 15/32in, 31/64in, 1/2in<br> Cutting angle string: 135 degree<br> Surface treatment: fully ground&nbsp;
