British Standard Center Drills
A Dormer British Standard Center Drill (BS328) is a type of center drill made from high-speed steel (HSS). These drills are designed to create precise center holes in workpieces, which are essential for accurate machining operations. Here are some key features:
1.High-Speed Steel (HSS): Provides excellent strength and durability, making it suitable for various materials, including steel, stainless steel, cast iron, and non-ferrous metals.
2.120° Point Angle: This angle helps in creating a precise starting point for drilling operations.
3.60° Countersink: The countersink angle allows for the creation of a conical surface, which helps in guiding the drill bit and preventing it from wandering.
4.Versatility: Suitable for both hand and machine use, making it a versatile tool for different drilling applications.
