HSS annular cutter set

The professional HSS YT-43400 hole saw drill bit set is designed for precise hole-making in structural steel, sheets, profiles, and other metal components. These types of drill bits are widely used in locksmithing, mechanical workshops, manufacturing plants, and during the assembly of steel structures, where accuracy, processing speed, and material waste reduction are crucial.

The hole saw drilling technology allows for the removal of only the material's circumference, rather than its entire volume, significantly reducing cutting resistance, shortening work time, and extending tool life. Made from high-speed steel (HSS), it offers high wear resistance and stable performance parameters even under intensive use.

Features and functions:

• hole saws for steel machining – the set is intended for making precise holes in steel and other metals of similar hardness, proving effective when drilling in steel profiles, pipes, sheets, and structural elements used in industry and construction
• efficient drilling with reduced resistance – the hole saw design limits the amount of material removed, resulting in less load on the machine, faster operation, and lower energy consumption, while also allowing for cleaner hole edges and greater accuracy
• high-quality HSS steel – drill bits made from HSS steel exhibit good resistance to high working temperatures, wear, and mechanical loads, demonstrating longer life and consistent machining even during continuous operation
• Weldon mounting – a standard mounting type that ensures stable positioning of the drill bit in the chuck and reliable torque transfer during operation
• set of most commonly used diameters – the set includes the most popular drill bit sizes used in assembly and workshop tasks, allowing for versatile applications without the need to purchase additional tools
• 2 guiding pilots – ensuring effective centering of the drill bits, core material ejection, and coolant delivery, contributing to work safety
