Description
- Versatile Cutting Range: These drill bits are designed for use on wood, plastics, stainless steel, thin sheet metal (steel and aluminum), body panels, and mild steel. They are not suitable for concrete or masonry.
- High-Performance Metal Drill Bits: Made from M35 cobalt steel with added molybdenum and cobalt, these bits achieve Rockwell hardness up to 67, offering exceptional heat resistance and longevity—up to twelve times longer than standard HSS drill bits. The titanium coating prevents rust and enhances wear resistance, ensuring sustained sharpness.
- No Center Punch Needed: Featuring 135° Quick-Cut points, these bits are self-centering and penetrate quickly with minimal pressure, reducing the risk of wandering. The straight shank design ensures a firm grip and accurate centering, compatible with standard drill chucks and round collet chucks. For best results, use at appropriate RPMs.
- Enhanced Grinding Processing: Each bit undergoes full grinding processing to achieve a smoother surface, reducing friction and increasing cutting speed for efficient drilling.
- Complete 13-Piece Set: Includes 13 HSS drill bits in sizes: 1.5mm, 2mm, 2.5mm, 3mm, 3.2mm, 3.5mm, 4mm, 4.5mm, 4.8mm, 5mm, 5.5mm, 6mm, and 6.5mm, all neatly packaged in one box.
