TRUE M35 COBALT HSS: Manufactured from premium High-Speed Steel containing 5% Cobalt (HSS-Co). This formula dramatically increases heat resistance and durability compared to standard HSS bits, allowing you to cut through tough metals like stainless steel, cast iron, and high-temperature alloys without dulling quickly. 50-PIECE BULK REPLACEMENT PACK: Small drill bits are prone to breaking during precision work. This set solves that frustration by providing 10 pieces each of the most commonly used small metric sizes: 1.0mm, 1.5mm, 2.0mm, 2.5mm, and 3.0mm. You will always have a sharp spare ready to go. PRECISION FULLY GROUND PROCESS: Unlike cheaper rolled-forged bits, these are fully ground from solid bars with a heavy-duty spiral flute design. This ensures excellent concentricity (no wobbling), faster chip ejection, and a cleaner cut in metal, wood, and hard plastics. VERSATILE STRAIGHT SHANK: Features a standard straight shank that fits firmly into all standard drill chucks and collets. Ideal for DIY projects, maintenance, jewelry making, and workshop tasks requiring precise, small-diameter holes in hard materials. BRONZE OXIDE FINISH: The amber/bronze finish is not just for looks; it provides an abrasion-resistant coating that holds lubricant better and resists corrosion, extending the tool life even in demanding workshop environments.

Stop Burning Through Standard Drill Bits on Hard Metals

If you have ever tried to drill through stainless steel with a regular black oxide bit, you know the frustration: smoke, heat, and a dulled tip within seconds. The Hymnorq 50-Piece M35 Cobalt Drill Bit Set is engineered to solve this problem.

Why Choose M35 Cobalt?
These bits are made from High-Speed Steel combined with 5% Cobalt (HSS-Co). Cobalt is not a coating that wears off; it is part of the steel alloy. This allows the bits to withstand extremely high temperatures generated when drilling hard metals, maintaining their hardness and cutting edge far longer than standard HSS bits.

The "Safety Net" for Precision Drilling
Small diameter bits (under 3mm) are delicate by nature. Even the most expensive bit can snap if the drill tilts slightly. We understand this reality. That is why we provide a bulk pack of the 5 most essential small metric sizes. Instead of buying one expensive bit and panicking when it breaks, you have 10 of each size at your disposal.

Size Specification (10 Pieces per size):

• 1.0mm (Length fits precision micro-drilling)
• 1.5mm
• 2.0mm
• 2.5mm
• 3.0mm

Recommended Applications:
✅ Excellent for: Stainless Steel, Cast Iron, High-Carbon Steel, Aluminum Alloy, Zinc, Wood, and Hard Plastics.
❌ Not for: Glass, Ceramic, Tile, or Concrete/Masonry.

Professional Tips for Drilling Metal:
1. Keep the drill vertical to avoid snapping these small bits.
2. For stainless steel, use a slow RPM and apply firm pressure.
3. Using cutting fluid or oil is highly recommended to extend the life of the bit even further.
