SDS drill or standard Hammer drill

SDS just means "tool less change system" i.e. keyless chuck

The main difference is between a true hammer drill or a rotary percussion drill.

If you have used both you will know the difference.

No! If it did it would be called TCS and it isn't???

Special Direct System

The name SDS comes from the German "Steck – Dreh – Sitz" (Insert – Twist – Stay). German-speaking countries may use "Spannen durch System" (Clamping System), though Bosch (who developed the system in 1975 for hammer drills) uses "Special Direct System" for international purposes.

This was its original meaning, but its now generally used across Bosch to indicate a 'tool less change system'

Horses for courses,,,,,,

If you just need to drill concrete / brick walls etc for rawlplugs'n'screws etc a decent Hammer drill is more than sufficient (I am still using my original Quattro that I bought when they forst came out - one of the better tools that I'v bought)

If you need to drill holes in granite &/or for pipes, cables etc, then an SDS is the chap.

I only have a cheap S.F item, but it's done me proud over the past few years.

I always thought it was "Secure Drilling System", you learn something new everyday!

I would go for a standard drill for lighter tasks and basic drilling with a separate SDS for heavier tasks. I have a Bosch 650w, Nutool heavy SDS and a SF special offer De Walt 2Kg SDS that came with a free 12v DW Cordless for £89.

I also have a Ryobi 14.4v hammer & BNPOO performance power 14.4v hammer.

I just love lots of tools, now I need a bigger shed.

well you got the tools to build one

I stand by my initial comment - if you want to buy just one drill, SDS is NOT the way to go.
The amount of time you REALLY need the features of an SDS drill compared to a normal hammer combi-drill is very small.

Cordless for general work (super convienient), Mains Hammer for when you need sustained power drilling wood and light masonry (unless you have an SDS) and SDS for serious masonry/demo work.

SDS and hammer drill there is no comparison! Great for hard screwdriving applications too! I <3 my Makita HR2450!

my elu sds drill is ohhh about 12 years old now i think. its been used for many many damp proof courses and hundreds of other jobs. still going strong though could do with a service i think. sometimes feels as if it misses a beat. only like £100 for the equivalent dewalt model now though
