What are the 5 types of drill bits?

20 Different Types of Drill Bits & Their Uses

• Twist Bits. Also known as high-speed bits, they resemble corkscrews and are some of the most popular bits.
• Brad Point Bits. Brad point bits come in handy when you need to make clean and precise holes.
• Masonry Bits.
• Rivet Bits.
• Spade Bits.
• Installer Bits.
• Step Bits.
• Auger Bits.

What are the different grades of drill bits?

There are four main types for consumer bits: low carbon steel, high carbon steel, high speed steel, and cobalt steel. From the left- machinist Cobalt, Standard cobalt, High Speed Steel, Black Oxide, Spade, non-stepped Uni-Bit, stepped Uni-Bit, Bi-Metal Hole Saw.

What is the hardest drill bit?

Carbide
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.

What is gold drill bit for?

For drilling into metal Metal bits are also known as high-speed steel (HSS) or twist bits. They are usually black but sometimes gold in colour (gold ones are usually specially coated for extra durability). Metal-drilling bits can be used for drilling plastic and wood, but you should never use wood bits to drill metal.

What is HSS drill bit?

HSS drill bits, an acronym for high speed steel drill bits are extremely hardwearing and particularly well designed for drilling into metal surfaces, as they are much more resistant to the heat generated from the fast speed operation. HSS bits can be also be used for drilling wood and plastic materials.

What is a TiN drill bit?

TiN is a hard ceramic coating that is often used on steel drill bits and other machine tooling, and it provides several benefits, mainly longer edge retention and reduced friction. In other words, TiN-coated drill bits should last longer than uncoated bits, and you can often push them faster too.

What is silver drill bit used for?

Silver and Deming drill bit can be used for limited drilling in light gauge steel. This use requires slow speeds, high quality cutting oil, and a smaller diameter of pilot hole. Drilling through aluminium, magnesium and other soft metals do not require less torque as steel.
