Frequently Asked Questions (FAQs)

1. What does SDS mean on a drill bit?

But what is an SDS drill? SDS stands for Slotted Drive Shaft or Slotted Drive System. SDS bits are inserted into the chuck to make a rotary hammer or a hammer drill.

2. Is SDS better than hammer drill?

However, SDS drills are more powerful than the standard hammer drill, making them well suited to more heavy-duty drilling applications. The two terms are sometimes used interchangeably, but if you need a drill for use with tough materials like concrete and masonry, an SDS drill will be the best option.

3. What is the difference between SDS and SDS Plus drill bits?

SDS and SDS Plus are interchangeable. The difference is that SDS Plus have 4 splines in the shank that hold it more securely. Both are 10mm shank size. SDS Max is 18mm shank size, so SDS Max bits are not interchangeable with SDS or SDS Plus.

4. Can you use SDS bits in a normal drill?

You should not use SDS bits in a standard drill. The chuck on a standard rotary or hammer drill is not designed for them. Standard bits can come loose, damage the drill and affect the quality of your work.
