What oil should be added to an impact drill?
2 Answers
Impact drills can be lubricated with grease. If you want to maintain and use it properly, you can purchase high-temperature grease that can withstand temperatures up to 320 degrees or higher. More details are as follows: How an impact drill works: An impact drill operates through both impact and rotation. If it only relies on impact, the effect would be minimal. It needs to achieve an impact frequency of over 40,000 times per minute to generate continuous impact force. It can be used on natural stone and concrete. Precautions: When using an impact drill, first connect it to the power source. Then, let it idle for a while to check its impact force and rotation sensitivity. During operation, ensure that the drill's pointer aligns with the working material. Additionally, wear safety goggles before starting the operation.
As an experienced renovation master, those who frequently use impact drills know that maintenance is crucial. For the gearbox, apply high-viscosity lithium-based grease, the kind similar to butter, to reduce gear wear. The gearbox is best lubricated with fluid 20-grade machine oil—just drip it into the oil filler hole until it overflows. Don’t rush to lubricate a new machine; wait about a year and assess the situation. A crucial reminder: always distinguish between a rotary hammer and an impact drill. Professional equipment like rotary hammers require 32-grade hydraulic oil, filled to about 80% of the oil reservoir’s capacity. Using the wrong oil can cause the machine to malfunction at best or even be permanently damaged. Also, remember to clean and apply some rust-proof oil if the tool won’t be used for a long time.
