Shock Resistance: Magnetic drill bits are designed to withstand high-impact forces. Drill screwdriver bit set is important when using them with tools like impact drivers, which deliver sudden and powerful rotational impacts. The shock-resistant design helps prevent the bits from breaking or becoming damaged under such conditions. Deep Bite Design: The deep bite design of the screwdriver bits allows them to engage more deeply with screw heads. This can reduce the potential for head slippage and improve overall work efficiency by providing a stronger connection between the bit and the screw. Non-Slip Serrated Blade: The screwdriver bits feature a non-slip serrated blade. This design helps to grip screws more effectively, reducing the likelihood of the screwdriver slipping out of the screw head during operation. This is important for maintaining a secure grip and preventing damage to the screw or work surface. Mechanics Principle Design: The design of the screwdriver bits takes into account mechanical principles. This includes considerations such as torque and impact forces. The design is intended to ensure that when the impact driver engages with the screw head, some of the resulting collision reaction force is absorbed by torsion, which can help prevent the cutter head of the bit from breaking. Hardness ≥ 62HRC: The hardness of the bit head is specified to be equal to or greater than 62HRC (Rockwell C scale). This high hardness level indicates that the bit material has been optimized for durability and can withstand considerable wear and stress without becoming deformed or damaged. Feature: 1.Made of high quality impact resistant steel. Hardness reached 62HRC which could be used on high strength working situations. 2.After touching the screw head Impact screwdriver The resulting collision reaction force partly absorbed by torsion Effectively prevent the cutter headfrom breaking. 3.Delicate slim waist design, thin waist buffer absorbs hard impacts from impact drivers So that the bit has good impact resistance. 4.Non-slip serrated bit, with certain magnetic and non-slip properties, can firmly fix the screw to the screwdriver. Suitable for various job scenarios, not easy to rust and longer service life. 5.Applicable equipment hand drill lithium drill electric screw driver electric screwdriver.
