HSS Twist Drill Bit Set 3–8 Piece Sizes Available for Steel Metal and General Drilling

This HSS twist drill bit set is designed for buyers who need flexible, compact drilling solutions at attractive price points. Available in 3-piece, 5-piece and 8-piece configurations, the set covers the most frequently used metric sizes for steel, metal and general purpose drilling. Each bit is manufactured from high speed steel with a standard 118-degree point angle, delivering reliable cutting performance for everyday applications in workshops, construction sites, repair shops and households.

The twist drill geometry is optimized for efficient material removal: two helical flutes guide the cutting action and carry chips out of the hole, while the precisely ground cutting lips maintain sharpness through repeated use. Because the set is offered in several piece counts, distributors and retailers can select the configuration that best matches their target customers, whether that means an economy 3-piece pocket set or a more complete 8-piece workshop kit.

• Flexible Set Configurations: Choose from 3-piece, 5-piece or 8-piece sets to match different retail channels and end-user needs.
• Quality High Speed Steel: HSS 4341 and M2 grades provide good hardness, toughness and wear resistance for general metal drilling.
• Standard 118-Degree Point: The conventional point geometry is easy to resharpen and works well for most steel, metal, wood and plastic materials.
• Efficient Twist Flute Design: Helical flutes remove chips quickly, reducing friction and keeping the bit cooler during extended drilling.
• Retail-Ready Packaging: Blister cards and pouches are designed for shelf display, with clear size markings for quick customer selection.
• Economical Pricing: Compact set configurations allow competitive retail pricing while maintaining dependable cutting quality.

These HSS twist drill bits are suited to general drilling in mild steel, aluminum, copper, wood and plastic. Common uses include furniture assembly, shelf installation, metal frame drilling, electrical conduit work, model making and routine home repairs. The 118-degree point performs reliably on flat surfaces and is particularly easy to resharpen, which makes these sets popular among buyers who prefer to maintain their tools over the long term.

For hardware stores and e-commerce sellers, the compact set formats are excellent impulse-purchase items that generate steady repeat sales. The uniform size steps within each set allow users to drill pilot holes, clearance holes and small mounting holes without owning a large collection of loose bits.

Sets are packed in printed blister cards, plastic pouches or poly bags according to the order requirement, then shipped in export cartons with proper cushioning. We support custom branding, size selection and packaging design for OEM and ODM projects. Each production lot undergoes hardness testing and cutting performance sampling to ensure consistent quality.
