One of the most common questions asked by any DIY enthusiast is what an SDS drill is. SDS means Special Direct System. The SDS drill system was invented in 1975 Bosch and ever since, it has been the most used tool by almost every handyman or DIY enthusiast. The SDS power tools have become the standard for industrial, professional, semi-professional, and home use. It is a powerful drill that is designed to drill into the hardest substances.
The three standard types of SDS drills available on the market are: SDS Plus, SDS Top and SDS Max. The SDS Plus drill is the smallest type and the most widely used SDS drill for professional and home usage. With a shank of 10 mm and a 40 mm insertion into the chuck, the SDS Plus drill come with hammers that are up to 4kg.
The SDS Top drill is not widely used although it comes with a 14mm shank which inserts 70mm into the chuck and hammers that are in the 2kg to 5kg. The SDS Max drill is the most widely used SDS drill for industrial purposes. It has an 18mm shank with three open groves and a locking mechanism. It inserts 90mm into the chuck and is rated for its hammers which are over 5kg. The SDS Max drills are the most powerful and can be used to drill into the hardest surface with little effort which is why this type is most commonly used for demolition work.
So how exactly does an SDS drill works? The cylindrical shank has various groves down its sides which provide the rotary force of the drill. An SDS drill also has a ball roller which makes it possible for the bit of the drill to move back and forth. One of the advantages of a SDS drill is that it makes it possible for tools to be exchanged since that it does not require a chuck key. A SDS drill is more powerful than a regular drill and provide flexibility and versatility. It is long-lasting and durable.
An SDS drill needs to be properly maintained. The chuck needs to be lubricated and cleaned frequently because if it is not, the drill can easily become damaged. Investing in a cordless SDS drill will save time, effort and money.
