Using penetrating lubricant on old fasteners increases the chances of successful extraction. Work carefully, take your time, and do not use an impact driver or screwdriver to avoid damaging the fastener or component. Use protective equipment. Apply oil if necessary. • This kit is designed for extracting broken fasteners: bolts, studs, bushings, and pins. • The kit is easy to use: simply select the appropriate drill bit and prepare a hole for the extractor. Then, select the appropriate extractor from the kit (which comes after the drill bit) and screw it into the desired fastener. Without changing the direction of rotation of the screwdriver/drill, the extractor will automatically remove the fastener because it has a reverse thread. This means that screwing the extractor automatically removes the fastener. • The drill bits are made of high-quality HSS4241 high-speed steel, which increases the tool's wear resistance. A titanium nitride coating provides additional wear resistance. • The extractors are made of bearing steel, which has high hardness, wear resistance, and contact fatigue strength, allowing the extractors to withstand increased, continuous loads. • This model comes in a metal case, allowing for easy access and quick identification of the required size during work.
