This is one beautiful set of cone and countersink bits!
With this kit you get 5 regular countersink bits plus 5 larger cone bits. This is an exceptional value for any woodworker. These bits are made of high quality alloy steel. It will last and last. The regular countersink bits range from 1/4 inch diameter to 3/4 inch diameter. The cone bits, being shaped like a cone, and be used to craft any size countersink from 1/16th inch to 1 3/8 inches. These bits are suitable for drilling wood, thin metal, copper, plastic and many other materials. The bits all have laser engraved sizes at each step size, insuring readability and proper sizing of your counter sink holes. I've tried over half of the bits, and I am very impressed! This is definitely a 5 star item!

Step drill bit set
Set comes with step drill bits and counter sink drill bits. I’ve only used the step drill bits on some soft metals and they work like they are supposed to with no issues. When and if i use them on thicker hard metal I’ll update.
