Twist drill bit - appearance and area of applications
The twist drill bit was invented as early as 1863 and owes its name to the twisted spirals ("helixes"), which ensure rapid removal of the metal chips produced and at the same time serve to supply lubricant. By the way, we also stock the right lubricants for your drilling work!
Appearance
In addition to a conical head, the twist drill bit has various cutting edges - usually main, secondary and transverse. The tip of the head has either a point angle of 118° or 135° for HSS drill bits (high-speed steel) or 142° for carbide drill bits.
The angle is important to make the drill bit insensitive to lateral or impact forces. Depending on the material, a higher or lower angle helps to reduce or increase the contact pressure. A small angle also helps to centre the drill bit and reduce the risk of slipping on smooth or curved surfaces .
Material
The twist drills bit are made of particularly resistant and robust material to guarantee a long service life time. Our drill bits are made of the following materials:
- HSS (high-speed steel)
- HSSG (high-speed steel, ground version)
- HSSE (high-speed steel with a cobalt content (Co) of 5%)
Application
As a rule, the twist drill bit is used for various metals (and is therefore also called a metal drill bit), but there are also drill bits adapted for wood, stone or plastics. We explain our range in detail in the next section.
Our range: high quality twist drill bit sets for all applications
With our various twist drill bit sets you can process all common materials. You will always find these drill sets for different materials in first-class, durable BAER quality. We always offer new, modern and innovative product solutions, therefore the program can change at any time. Currently you can find in our product range, for example, the following popular twist drill bit sets:
#1 Twist drill bits for all materials
- HSSE Power drill bit (for all materials), drill bit set in 1 - 10 mm and 1 - 13 mm variants, with three-flats shank. It is a drill body made of high-speed ground steel with 5% cobalt alloy for extremely precise drilling and excellent heat resistance. Visually, this twist drill bit set stands out with its black and gold surface treatment. This makes it possible to machine materials that are difficult to machine.
- HSSE Extreme drill bits (for all materials): 0.3 mm to 16 mm. These twist drill bits are made of high-alloy HSSE/Cobalt steel and are therefore particularly stable, heat-resistant and guarantee high concentricity. They are suitable for machining various steels, iron, bronzes, cast materials as well as high-strength alloys and stainless steel (V2A, V4A, INOX).
- HSSE twist drill bits with reduced shank (for all materials): 13.5 mm to 20 mm. This drill bit has a special cross grinding (called split point) and a cobalt alloy. It is extremely stable and heat resistant, making it ideal for machining high-strength materials and stainless steels.
#2 Twist drill bits for general use
- HSS twist drill bits with reduced shank for general use: 13.5 mm to 30 mm
- HSSG mini twist drill bits for general use: 0.2 mm to 1.95 mm
These are standard drill bits for drilling steel and cast steel (alloyed and unalloyed), gray cast iron, malleable cast iron, nodular cast iron, sintered iron, nickel silver, graphite.
#3 Special twist drill bits for specific materials - in a set
- Stone and concrete drill bit set, 15 pieces, 3 to 10 mm. Here you will find all common sizes, even in multiple versions. The double-edged carbide tip (89 HRC) is particularly resistant, the drill body made of carbon steel ensures a long service life time. With this you can work particularly precisely and quickly!
- SDS-Plus hammer drill bit set, 7 pieces, 5 to 12 mm. These industrial-quality hammer drill bit sets have a four-fluted drill head that allows you to drill precise holes even in reinforced concrete. The long service life time and excellent performance are another plus. This twist drill bit is suitable for all hard building materials, for example, natural stone, building granite or reinforced concrete.
- Wood drill bit set, 15-piece, 3 to 10 mm. The durable wood drill bit set in tested industrial quality is also ideal for do-it-yourselfers. It is predestined for precise work, as the center point allows very accurate drilling. Thanks to the C45 drill body, this is very durable and also guarantees a long tool life time.

Twist drills are versatile tools for drilling holes in various materials. Their spiral geometry facilitates cutting and the removal of chips via the twisted flutes. They are distinguished by the following features:
1. Tool types
- Metal drill bits: For steel, aluminum and other metals.
- Wood drill bits: Specially for wood with centering tip.
- Masonry and concrete drill bits: With carbide tip for hard materials.
2. Cutting edge geometry
- Point angle: Varies depending on the material (e.g. 118° for soft materials, 135° for hard materials).
- Tip grinding: Adapted to the material for clean tapping and optimum cutting performance.
3. Bevel shapes
- Cross bevel: Reduces feed force, ideal for metal.
- Flat bevel: For soft materials such as wood.
- Special shapes: For special applications, e.g. stone.
- HSS (high speed steel): Standard material for general applications.

- Precise machining: Enable particularly precise, chatter-free work.
- Versatile application: Suitable for various materials such as metal, wood and plastics.
- Aesthetic finish: Ensures a clean and professional appearance of screw connections.
- Prevents material damage: Prevents the material from tearing when screwing in screws.
Countersinks are indispensable tools for precise and clean screw connections in various craft and industrial sectors.
Core hole drills are special tools for creating holes that serve as preparation for thread cutting:
- Function: Produce holes with a central core.
- Areas of application: Metalworking, construction (concrete, stone) and piping.
- Advantages: Less wear, faster advance, especially with large diameters and hard materials.
Core hole drills are ideal for precise and efficient holes that serve as the basis for threaded inserts.
For optimum drilling results, specialized drill bits for different materials are recommended:
- Wood drill bits: Have a centering tip and wide cutting edges for clean holes in wood.
- Metal drill bits: Made of HSS or HSSE, with a special point angle for efficient drilling in metals.
