Frequently Asked Questions (FAQs)
1. What are long drill bits called?
A unibit (often called a step drill bit) is a roughly conical bit with a stairstep profile. Due to its design, a single bit can be used for drilling a wide range of hole sizes. Some bits come to a point and are thus self-starting. The larger-size bits have blunt tips and are used for hole enlarging.
2. Can you use a carbide bit in a drill?
Carbide tips can drill through hard, non-metallic materials like masonry, while full-body drill bits are primarily used in automated processes. They stay sharper longer than cobalt drill bits do, and they have a higher cutting speed. They can also handle higher temperatures.
3. What are carbide drill bits good for?
Carbide (Carb) is the hardest and most brittle of the drill bit materials. It's used mostly for production drilling where a high-quality tool holder and equipment is used. It should not be used in hand drills or even drill presses. These drill bits are designed for the most demanding and hardest materials.
4. Are carbide or titanium drill bits better?
Titanium-coated HSS drill bits produce less friction. They're tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits.
