●FOUR FLUTE STEP DRILL BIT - Deflection during cutting is a common problem with ordinary step drills, but our four flute step drill bit is designed to provide greater stability. With improved accuracy and cutting speed, its perfect for stainless steel drilling and offers several times the service life of ordinary step drills.
●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, its 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. Its 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. Thats why weve 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.
