RS PRO High Speed Steel (HSS) Metric Extra Length Twist Drill Bit 7 mm x 250 mm Overall Length 522-6796

RS PRO 522-6796 is a Metric Extra Length Twist Drill Bit manufactured from High Speed Steel (HSS), specifically engineered for demanding industrial applications requiring precise and efficient drilling. This drill bit measures 7 mm in diameter and has an overall length of 250 mm, featuring a straight cylindrical plain shank of 7 mm that ensures secure tool holding during use.

The drill bit has a 118° drill point angle, optimized for right-hand cutting with two helical flutes designed to efficiently evacuate chips and reduce heat build-up. It is vapour-plated with a rolled spiral flute and a ground point for enhanced cutting performance and durability. Compliant with BS 328, DIN 340, RN & ISO standards, this drill bit guarantees consistent quality and reliable operation in a variety of industrial environments.

This drill bit is suited for drilling a wide range of materials including wood, plastic composites, mild and cast steel (both alloy and non-alloy), grey cast iron, tempered castings, sintered materials, graphite, and nodular iron. The HSS material is ideal for maintaining strength and heat resistance during high-speed rotations typically between 500 to 700 rpm.

The RS PRO HSS Long & Extra Long Series are designed for extended use, capable of drilling up to ten times the diameter length before the flute requires cleaning to maintain performance. This drill bit is fit for use in manufacturing, mechanical maintenance, metal fabrication, and laboratory settings with demanding precision and durability needs.

The drill bit is made from High Speed Steel (HSS) which provides excellent heat resistance during high-speed drilling. It has an overall length of 250 mm and a shank size of 7 mm with a plain cylindrical shank. The drill bit features a 118° point angle with a right-hand cutting direction and a helical two-flute design.

Complies with standards BS 328, DIN 340, RN & ISO for assured quality and durability. Suitable for drilling wood, plastics, mild and cast steel, grey cast iron, sintered materials, graphite, and nodular iron. Manufactured in China ensuring industrial grade build quality.

Rolled spiral flute with ground point and vapor plating enhances cutting performance and lifespan. Part of the HSS Long & Extra Long Series capable of drilling up to 10x the drill diameter before clearance is needed. Designed for precise and easy drilling of metals, special and hardened steels and alloys.
