RS PRO Cobalt High Speed Steel Drill Bit 7.5mm Diameter, 109mm Overall Length, 4 Flutes, Cylindrical Shank, Amber 216-448

RS PRO model 216-448 is a high-performance cobalt high speed steel drill bit set designed for precision drilling in demanding industrial and workshop environments. Each drill bit measures 7.5mm in diameter with an overall length of 109mm, making it suitable for a wide range of hard material applications.

The drill bits are manufactured from high-speed steel blended with 5% cobalt, enhancing their strength, heat resistance, and durability during heavy-duty operations. The 4-flute helical design enables efficient chip evacuation, ensuring smooth cutting and reduced heat buildup.

The cylindrical shank of 7.5mm diameter provides a secure fit for power drills and machining tools, while the amber finish protects the bits from corrosion, extending their service life. The 135° split point angle allows for accurate, clean hole making with minimal wandering, optimized for right-hand cutting direction.

This set complies with DIN 338 standards, guaranteeing consistent dimensions and compatibility with fasteners and components that require standard-sized holes. Ideal for drilling tough materials such as hardened steel, stainless and alloy steels, cast iron, and titanium, these drill bits are perfect for industrial, engineering, manufacturing, and maintenance use.

Containing 10 pieces, the kit caters to general workshop needs and professional applications alike. It provides reliable performance for tasks involving metal fabrication, assembly, repairs, and precise drilling in demanding environments.
