HSS Cobalt Drill Bits by SD Tools

Why choosing HSS Cobalt Drill Bits at SIDS DIY?

The twist drill bits are the most popular and frequently used type of drill bits today because they are essential in several jobs. The tip of the drill bits cuts the material and the flute’s job is to remove the swarf from the hole and keep the hole straight.

Hardware brands can change the geometry and the material to produce different specialized versions of the twist bit. The drill bit with a point angle of 118 degrees is the most famous type as it is suitable for a large number of materials such as wood, plastic, metal. Because it is so versatile, we highly recommend new handymen using this drill bits type for their project. If you want to drill soft material, we recommend using a 90-degree one. If you want to drill through hard material like metals, a 150-degree, and lower RPM is more suitable. Drill bits with a flat cutting point, as its name suggested, will be a wise choice if you want to drill a flat-bottom hole.
