Product Description
Hymnorq 19-Piece Metric Twist Drill Bit Set (1.0mm-10mm), Budget-Friendly HSS 4241 Roll-Forged Drill Bits with Anti-Rust Gold Finish, Straight Shank for Wood, Plastic & Soft Metals
- COMPLETE METRIC RANGE: Includes 19 frequently used metric drill bits from 1.0mm to 10.0mm in 0.5mm increments. This comprehensive size range covers most of your daily household repair and light DIY drilling needs.
- BREAK-RESISTANT & HAND-DRILL FRIENDLY: Manufactured using a hot roll-forged process, these bits retain their continuous metal grain structure, offering superior toughness and flexibility compared to brittle fully-ground bits. They easily absorb the slight side-loads and wobbles typical of standard hand drill use without snapping.
- OPTIMIZED FOR SOFT MATERIALS: Crafted from High-Speed Steel (HSS) 4241, these bits are specifically designed for efficient drilling into wood, plastics, PVC, and thin/soft metal sheets like aluminum. (Note: Not recommended for hard steel, thick iron plates, or masonry).
- ANTI-RUST GOLD FINISH: Featuring a decorative gold-toned coating that effectively prevents rust and extends the shelf life of the bits during storage. This protective finish provides excellent corrosion resistance for long-lasting everyday use.
- UNIVERSAL FIT & ECO-PACKAGING: Features a standard 118-degree point and straight shank design for easy, secure attachment to all standard drill chucks. To provide you with the most budget-friendly solution, this set is simply packed in a plastic bag and paper box without an expensive indexed case.
