Mini Hss Drill Bit 0.8mm 2pc
Diameter: Ø0.8mm
This 0.8mm High-Speed Steel (HSS) Mini Drill Bit 2-Piece Set is engineered for high-precision tasks that require both strength and a delicate touch. Crafted from premium HSS, these bits offer exceptional heat resistance and durability, ensuring they stay sharp significantly longer than standard carbon steel bits. The high-speed steel construction allows for clean, burr-free holes even when working at higher RPMs, making them ideal for drilling through soft metals, plastics, hardwoods, and composite materials.
Designed specifically for intricate work, the ultra-fine 0.8mm diameter is a staple for electronics enthusiasts, jewelry makers, and scale modelers. These bits feature precision-ground flutes that facilitate rapid chip removal, which prevents clogging and reduces the likelihood of bit breakage—a common challenge with micro-drills. Whether you are perforating a printed circuit board (PCB), crafting custom jewelry, or detailing a miniature, these bits provide the accuracy needed for professional-grade results.
The set comes as a convenient 2-piece pack, providing a reliable backup to ensure your project isn't sidelined by a single broken bit. Their universal straight-shank design ensures compatibility with most mini rotary tools (like Dremel), pin vises, and specialized micro-drill presses. Compact yet robust, this set is an essential addition to any hobbyist's or technician's precision toolkit.
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.
The shank of the rotary cutter is securely locked in place by fitting it in the corresponding collet or making use of a keyless chuck.
Rotation speed:
Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can normally be found on the packaging.
All materials react differently to speed and will need the tool bit to rotate slower. It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.
The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
