Diameter: Ø3.2mm
This 3.2mm High-Speed Steel (HSS) Mini Drill Bit 2-Piece Set is a versatile essential for hobbyists, technicians, and DIY enthusiasts. This specific size—equivalent to the standard 1/8 inch—is one of the most popular choices for general-purpose drilling in workshops, creative studios, and home repair kits.
Forged from premium High-Speed Steel, these bits are engineered to withstand higher temperatures and maintain a sharp cutting edge much longer than standard carbon steel. This durability makes them ideal for sustained use without the risk of rapid dulling or deformation under the heat generated by high-speed rotation.
The bits feature precision-ground flutes and a sharp twist geometry that ensures smooth, clean, and burr-free holes. This design facilitates efficient chip removal, which significantly reduces friction and minimizes the risk of the bit binding or the material cracking during operation.
Whether you are working with soft metals like aluminum and copper, or tougher materials like hardwoods, dense plastics, and fiberglass, these 3.2mm bits offer the biting power needed for a professional finish. They are particularly useful for creating mounting holes or preparing surfaces for fasteners and hardware.
Sold as a convenient 2-piece pack, this set provides a reliable backup to keep your workflow uninterrupted. Having a spare bit on hand is a practical advantage, ensuring you can complete your project even if one bit becomes worn through heavy use or high-volume tasks.
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.
