This 7-piece Metric HSS Drill Set is a collection of solid twist drills intended for general-purpose metalworking and workshop use. The set is designed to produce accurate diameters in ferrous and non-ferrous metals, plastics and other common engineering materials when used in hand-held drills or drill presses.

Each drill is manufactured from M2 high-speed steel (HSS M2), providing the hardness and heat resistance needed for sustained cutting at moderate spindle speeds. The drills are produced to the dimensional profile of DIN 338 for solid twist drills and are made to conform with recognised ISO and BS dimensional and tolerance guidelines for metric drills. The bits have a ground flute with a standard 118° point geometry suitable for general drilling; selected sizes may feature a split point to reduce walking on start-up. Shanks are straight cylindrical to fit standard three-jaw chucks and most drill holders.

Typical applications include drilling through mild and medium-carbon steels, aluminium and non-ferrous alloys, plastics, GRP and other fabrication materials. Industries that commonly use this type of set are light engineering and fabrication, maintenance and repair, automotive workshops, electrical and plumbing trades, and general DIY and prototyping work. The set is particularly useful for maintenance teams and small workshops that require a compact selection of metric sizes for routine tasks.

Key benefits of the M2 HSS construction are improved wear resistance and the ability to run at higher cutting speeds compared with carbon steel drills, while the factory ground flutes and point geometry aid hole accuracy and chip evacuation. The finish reduces friction and provides a degree of corrosion protection in workshop environments. Compatibility is broad: these drills fit standard chucks, drill presses and many portable power drills used in commercial and domestic settings.
