SDS Wood Bits?

[Roger Mills]

I see that Lidl have some SDS-Plus bit sets (chisels, etc.) coming up soon - but one of the sets contains wood augers. Why would you use a wood auger in an SDS drill - or am I missing something?

Saves carting another drill around. On my SDS , I can turn off the hammer action. I even have a conventional chuck which goes into the SDS one.

Having seen someone drill replacement oak beams for a 16c house I think the power and (unless cheap) clutch cd also be helpful.

The slower rotational speed and extra torque can be handy for this application. Its also convenient since the bits are quick to change and don't slip in use.

SDS is just the type of chuck fitted. It is not a type of drilling action.

[Bob Minchin]

Whilst we are on the topic, what does SDS stand for?

[dennis]

Some German thing..

which has been called special direct system on some English web sites.

Steck, Dreh, Sitzt

Steck-Dreh-Sitz = Insert-Twist-Stay

I used to use them often when my Hilti TE6A was my main drill - as others have said, it saved changing drills.

Now I like the Bosch Selfcut speed bits for mutilating joists.

Most of my body* prefers the Armeg quad-flute wood beaver drills, the stubby version used in an impact driver avoids the need for an angle-drill.

[*] one of my thumbs is less keen.

[Roger Mills]

Makes sense. But I hope they come with a clear warning to use rotate only - with no hammer action - otherwise the spiral lead screws ain't going to last very long!

[ARW]

Is that an adapter that plugs into the SDS or a change of chuck?

I have had SDS drills where you literally swap the chuck.

[charles]

It's a normal looking chuch with an SDS fitting.

[Andrew]

More expensive drill bits, ...

[John Rumm]

Steck Dreh Sitz which translates roughly to "Insert, twist, stay".

Never use the Jacobs chuck on hammer!
