Drill efficiently and accurately—one bit for multiple jobs! This multi-purpose HSS twist drill bit is designed for metal drilling, woodworking, plastic hole drilling, aluminum cutting, PVC pipe boring, and daily DIY crafts. With its classic spiral flute design, high-quality material, and user-friendly details, it easily handles drilling tasks on various materials, making it an essential tool for professional technicians, decorators, repair workers, and DIY enthusiasts.
Crafted from premium High-Speed Steel (HSS-4241) via precision rolling, the drill bit abandons the flimsy texture of ordinary steel. It undergoes triple heat treatment: vacuum quenching, high-temperature tempering, and low-temperature stabilization, achieving a hardness of HRC 62-65. This ensures excellent wear resistance and impact toughness— the cutting edge won’t chip, crack, or deform during drilling, even when working continuously on high-hardness materials like carbon steel and cast iron. The bit maintains sharp cutting performance, eliminating the hassle of frequent replacements. Its surface features double anti-rust protection: oxide blackening + rust-resistant coating, which effectively resists moisture and oil corrosion, reduces friction during drilling for smoother operation, and extends service life for worry-free storage and use.
Key design highlights enhance efficiency and precision:
- Scientific double spiral flutes: Optimized to a 30° golden spiral angle, the flutes quickly expel wood chips, metal shavings, and plastic debris during drilling. This prevents clogging that causes bit jamming or rough hole walls, ensuring clean, smooth holes without the need for secondary sanding.
- 118° standard self-centering tip: Featuring a symmetrical double cutting edge design, the tip offers strong self-centering ability. No extra marking is needed—just place the tip and drill straight. Even beginners can create perfectly straight holes without deviation or slipping.
- Precision-ground cutting edges: The edges are finely polished for 40% sharper cutting performance, reducing resistance and boosting drilling efficiency by 30%. Whether drilling through thin metal sheets or thick solid wood, it delivers fast, effortless results, significantly cutting down work time.
User-friendly details meet diverse needs:
- Complete size range: Covers common sizes from 1mm to 13mm, satisfying drilling requirements from small screw holes to larger apertures.
- Standard shank design: Compatible with most electric drills, impact drills, bench drills, and drilling machines on the market. Easy to install and remove without additional adapters.
- Multi-material compatibility: The reinforced cutting edges handle soft materials (wood, plastic, aluminum, PVC) and hard metals (carbon steel, cast iron, copper) equally well. Truly a “one-bit-for-all” tool, eliminating the need to switch bits frequently and reducing tool costs.
Versatile applications: Ideal for metal sheet drilling, furniture installation, plastic processing, aluminum chamfering, screw hole prepping for home repairs, and DIY model making. With its durable build, efficient chip removal, and precise centering, every drilling task becomes smooth and effortless. Tackle all your drilling needs with confidence!
