## Summary description

HSS drill bit 7.0 mm (MPN DT5551) for general-purpose metal and wood drilling. Made of high-speed steel (HSS) to maintain hardness at elevated temperatures, suitable for handheld and machine use. Designed for drilling holes of 7.0 mm diameter in ferrous and non-ferrous metals, plastics and timber in construction, maintenance and workshop tasks.

## Long description

HSS drill bit 7.0 mm is a general-purpose cutting tool made from high-speed steel for drilling 7.0 mm diameter holes in a range of materials. Designed for use with hand-held drills and drill presses, this drill bit maintains cutting hardness at elevated temperatures and delivers consistent hole size and straightness for routine construction, maintenance and workshop tasks. The geometry is suitable for ferrous and non-ferrous metals, plastics and timber, making it a versatile item for professional and DIY tool kits.
Advantages
This HSS 7.0 mm drill bit offers reliable heat resistance and hardness retention during continuous drilling, reducing wear compared with standard carbon steel bits. It provides accurate 7.0 mm hole sizing and good edge life across mixed materials, while remaining compatible with common drilling equipment. The single-piece HSS construction ensures rigidity and minimizes wobble, giving consistent results in through-holes and clearance holes.
Suitable for
 Drilling 7.0 mm holes in ferrous metals (steel, iron)
 Drilling 7.0 mm holes in non-ferrous metals (aluminium, copper)
 Drilling holes in plastics and synthetic materials
 Creating pilot or clearance holes in timber and composite boards
 General-purpose workshop, maintenance and construction drilling tasks
Key specifications
 Material: High-Speed Steel (HSS)
 Nominal diameter: 7.0 mm
 Shank type: cylindrical (suitable for standard drill chucks)
 Intended use: metal, plastic, timber
 Compatibility: handheld drills and drill presses
How to use
Secure the HSS 7.0 mm drill bit in the drill chuck, ensuring it is correctly centred and tightened. Choose an appropriate spindle speed for the material: lower speeds for hard or ferrous metals, medium to higher speeds for softer metals, plastics and wood. Use cutting lubricant when drilling ferrous metals to reduce heat and extend tool life. Apply steady pressure, keep the drill perpendicular to the work surface, and clear chips frequently for clean holes and stable cutting. For precision holes, pilot or start with a centre punch on metal surfaces.
Usage recommendations
For longest life and consistent results, use cutting fluid when drilling steels, avoid excessive feed that can cause heat build-up, and replace the bit when wear or chipping compromises hole quality. Match drill speed to material hardness and use appropriate personal protective equipment when drilling.
