Diameter: Ø1.2mm
This 1.2mm High-Speed Steel (HSS) Mini Drill Bit 2-Piece Set is a versatile and essential tool for enthusiasts and professionals who demand precision without sacrificing strength.
Forged from high-grade HSS, these bits are specifically treated for superior heat resistance and edge retention. This advanced construction allows them to maintain their sharpness through repeated use in demanding materials, outperforming standard carbon steel alternatives.
The 1.2mm diameter offers a perfect middle ground for micro-drilling. It is large enough to provide structural stability and ease of use, yet fine enough for the high-detail work required in jewelry making, electronics, and model engineering.
Designed with a classic twist geometry and precision-ground flutes, these bits ensure efficient chip evacuation. This feature is critical for minimizing friction and preventing the bit from 'walking' or snapping—a common frustration when working with smaller diameters.
These bits are highly effective for creating clean, uniform holes in soft metals like aluminum and brass, as well as plastics, acrylics, and various hardwoods. Whether you are installing mounting hardware on a prototype or boring delicate pilot holes, they deliver professional-level accuracy.
The set includes two identical bits, providing a practical solution for busy workshops. Having a backup on hand ensures that your project isn't sidelined if a bit becomes worn or accidentally breaks during a complex task.
Application:
- Small pilot holes, craft work, model building, instrument making.
- Precision holes in sheet metal, electronics housings, model engineering.
- Drilling mounting holes in plastics & acrylic panels and enclosures.
- Fine detailed hole drilling.
