RS PRO HSS Jobber Drill Bit Set, Titanium Nitride Coated, 75mm Overall Length, 4mm Shank, 4 Flutes, Helical, Box of 213-821

RS PRO 213-821 HSS Jobber Drill Bit Set is designed for precision and durability, making it an essential tool in industrial, fabrication, and maintenance environments. This set consists of 10 high-speed steel drill bits, each featuring a robust titanium nitride coating to provide enhanced surface hardness and improved wear resistance.

With a 75mm overall length and 4mm shank diameter, these bits are suitable for both hand and machine drills, enabling versatility across various workshop and field applications. The helical flute design ensures efficient chip removal and smooth drilling processes, while the right-hand cutting tip with a precise 118° drill point angle delivers accurate starts and minimizes walking on workpieces.

Constructed from quality high-speed steel, the drill bits maintain their integrity even under high-speed and high-temperature conditions, making them the preferred choice for repetitive drilling in metals such as steel and aluminum, as well as wood, plastics, and composite materials. The titanium nitride coating further reduces friction and heat buildup, prolonging tool life and enabling cleaner, faster cuts.

Each bit has a cylindrical shank type, facilitating secure mounting in standard drill chucks. The set complies with BS 328-ISO 235/1 and DIN 338 standards, attesting to its industrial-grade manufacturing and performance. The jobber length format provides extra reach for deeper drilling tasks, while the combination of four flutes and helical geometry enhances cutting performance in varied substrates.

This drill bit set is ideal for use in manufacturing, mechanical repair, laboratory setups, construction, HVAC maintenance, and professional workshops. Whether employed in fabricating metal parts, assembling wooden structures, or installing fixtures in composite panels, these drill bits support high-precision outcomes.

High-speed steel construction ensures strength and durability for repeated use. Titanium nitride coating provides superior hardness and reduced tool wear. Helical flutes enhance chip evacuation and minimize resistance. Consistent jobber length delivers versatility for standard and deep drilling tasks.

Complies with leading industrial standards for quality assurance. Perfect for engineers, machinists, maintenance personnel, and construction teams in demanding technical settings.
