Matework 4 Spiral Flute Step Drill Bit Set, M35 Cobalt Unibit 3Pcs

Key features

• Step Drill Bit
• M35 COBALT HSS - For hard materials, M35 cobalt HSS is the way to go. With its high hardness (HRC 64-66), red hardness, and wear resistance, it's perfect for the toughest jobs. And thanks to proper heat treatment, it boasts higher toughness and bending strength than ordinary high-speed steel.
• TiAlN COATING - Our TiAlN coating is a cutting-edge material with exceptional properties. It's extremely hard, can withstand high oxidation temperatures, and has excellent thermal hardness. Plus, it boasts strong adhesion, a low friction coefficient, and low thermal conductivity, making it an ideal choice for demanding applications.
• LARGER CUTTING ANGLE - When it comes to drilling hard materials, the angle of the drill tip matters. That's why we've designed our drill bits with a 135° cutting angle. This angle reduces self-wear and provides a larger stress area, resulting in cleaner, more efficient drilling.
• TIPS - Use these tips to keep your drill in top condition: add cutting oil or spray water to cool during continuous use, the start-up speed will be slower due to the larger cutting angle, any quality problems, please feel free to contact us . We stand behind our products and back them with a 100-day warranty for your peace of mind.
