RS PRO 522-6594 Metric Extra Length HSS Twist Drill Bit is engineered for industrial drilling applications requiring precision and durability. Crafted from high-speed steel (HSS), it ensures outstanding resistance to heat build-up at high drilling speeds, making it suitable for metals, special steels, and alloys.
This drill bit features a 3.3mm plain cylindrical shank compatible with most standard chucks, and an overall length of 160mm providing extra reach for deep drilling tasks. The 118° point angle delivers clean and efficient drilling by minimizing walking and enhancing cutting accuracy.
The two flutes are helically twisted to facilitate effective chip ejection, reducing clogging and overheating during operation. The right-hand cutting and ground-point design allow smooth penetration into a variety of materials including wood, plastics, mild and cast steels, grey cast iron, tempered castings, sintered materials, graphite, and nodular iron.
Manufactured to conform with BS 328, RN & ISO, and DIN 340 standards, this RS PRO drill bit guarantees consistent quality and reliability for industrial, manufacturing, construction, and maintenance applications.
The HSS extra length design permits drilling depths up to ten times the bit diameter before requiring flute clearing, thus enhancing productivity and reducing downtime. Durable High Speed Steel construction provides heat resistance and longevity.
160mm overall length offers extended drilling reach. Plain 3.3mm shank fits standard tool holders. Two helical flutes improve chip removal and cutting efficiency. 118° point angle ensures accurate and clean drilling. Complies with BS 328, RN & ISO, and DIN 340 standards for industrial quality.
Right-hand cutting suitable for various material types. Suitable for metals, wood, plastics, cast iron, and other engineering materials.
