Specification AgeRangeDescription : adult Brand : OSTSOYYD BulletPoint : Micro Drill Bits BulletPoint1 : M35 Cobalt FOUR FLUTE STEP DRILL BIT:High Performance M35 Cobalt Material: Made from M35 cobalt, these drill bits contain approximately 5% cobalt. This high - speed steel alloy offers excellent wear resistance, high hardness, and red hardness. It cuts faster and lasts longer than standard M2 steel, ensuring efficient and long - lasting performance during drilling operations BulletPoint2 : Step Drill Bits Four Flute Design: The four flute construction provides small chip loads and enables quicker chip removal. This not only improves the drilling speed but also helps in maintaining the accuracy of the hole. The flutes are precision - ground, maximizing accuracy and efficiency along the full working surface of the bit BulletPoint3 : TiAIN Coating and Large Cutting Angle: The TiAIN (Titanium Aluminum Nitride) coating enhances the bit's hardness and wear resistance, protecting it during high - speed and continuous use. Additionally, the large cutting angle allows for self - centering and quick penetration with less pressure, reducing the risk of "walking" or "wandering" during drilling, and no center punch is needed BulletPoint4 : Exceptional Drilling Capability: 9 size Includes 1/4",5/16",3/8",7/16",1/2",9/16",5/8",11/16",3/4" Our step drill bits are engineered to handle a wide range of materials with ease.
