SUBORUI ODM OEM M2 4341 4241 M35 Co HSS Fully Ground Straight Shank Titanium Stainless Steel Twist Drill Bit for Metal Iron

Key features

1. Material Technology

With high-speed steel (HSS) alloyed with cobalt (4341/4241/M35 Co), you can maintain sharpness and durability at high temperatures, outperforming standard HSS bits by ~30% in heat resistance*. The cobalt-infused alloy ensures superior hardness for drilling through tough metals like steel and cast iron.

2. Performance Parameters

With a titanium nitride (TiN) coating, you can achieve 2x longer lifespan compared to uncoated drill bits* by reducing friction and wear. The 20mm diameter and 20mm working length provide precise drilling in metal and hard materials, ensuring consistent hole accuracy.

3. Interactive Design

With a helical flute design, you can ensure efficient chip removal and reduce overheating, improving drilling efficiency by ~25% over straight-flute bits*. The straight shank (DIN 338 standard) guarantees compatibility with most power tools for seamless operation.

4. Certification Standards

With CE, RoHS, and EPR certifications, you can meet international safety and environmental standards, ensuring compliance in EU markets unlike uncertified alternatives*. The EPR certifications (Germany/France) reflect commitment to sustainable packaging practices.

5. Scenario Solutions

With precision engineering for metal and hard materials, you can handle demanding commercial applications, delivering 50% faster drilling in steel compared to general-purpose bits*. The hexagonal shank end provides secure gripping in chucks, ideal for workshops and industrial settings.
