There are four standard sizes of SDS: SDS Quick, SDS-plus (or SDSplus or SDS+), SDS-Top and SDS-max.
What is the difference between SDS SDS Plus and SDS Max?
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.
What is the largest diameter SDS Plus bit?
SDS-plus is the most common by count of tools manufactured, with masonry drills from 4 mm diameter to 30 mm (and from 5/32" to 1-1/4") diameter ordinarily available.Mar 27, 2019
Are all SDS shanks the same?
All SDS-Plus shanks are the same, just as all SDS-Max and Spline are the same size. Another point of confusion for the tools is with the two types of larger hammers produced, the demolition hammers vs rotary drill hammers.Jan 22, 2009
What do SDS sizes mean?
A: In North America, it's how power tool companies rate the tools. The larger the number, the more powerful the tool. The SDS Max tool holder is standardized, so any SDS Max bit will fit any SDS Max tool. The larger and deeper the hole, the larger the hammer you need.
Are SDS drill bits different?
SDS Plus bits are generally thinner and smaller than SDS Max bits. ... Thinner SDS Plus is generally for lighter duty work--mostly for dr illing smaller holes; SDS Max is for heavier duty work--for drilling larger holes. SDS Plus and SDS Max tools generally tend to have either one, two, or three capabilities.Jun 26, 2019
Are hammer drill bits universal?
The connection types are different and not interchangeable, so be sure to buy the bit to match your hammer. In general, you move from SDS-Plus to SDS-Max as the hole diameter you need to drill increases, though there is plenty of overlap in the middle diameters.May 29, 2019
What's the difference between SDS max and SDS Plus?
The most fundamental difference between SDS Plus and SDS Max lies in terms of size. SDS Plus bits are generally thinner and smaller than SDS Max bits. ... Thinner SDS Plus is generally for lighter duty work--mostly for dr illing smaller holes; SDS Max is for heavier duty work--for drilling larger holes.Jun 26, 2019
How are SDS drills sized?
There are three standard sizes of SDS: SDS-plus (or SDSplus or SDS+), SDS-Top and SDS-max. SDS-plus is the most common by count of tools manufactured, with masonry drills from 4 mm diameter to 30 mm (and from 5/32" to 1-1/4") diameter ordinarily available. ... Standard lengths are 12 to 21 inches (300 to 530 mm).Mar 27, 2019
What does 1 inch SDS mean?
For instance Bosch has a couple SDS-Plus Bulldog hammers; one is a 1” SDS-Plus & the other is a 1-1/8” SDS-Plus. This inch rating refers to the solid drilling diameter capacity or basic power of the drill, not a different size SDS-Plus shanks. ... These are also sometimes called combination drills.Jan 22, 2009
