SDS HSS drill bits

[lanham]

Can anyone recommend reasonably priced HSS bits (for wood and metal) for a SDS drill? I cannot seem to find any anywhere.

Define "reasonably priced"! I presume the likes of Toolstation are too expensive?

 

[lanham]

No, they are not too expensive if they are any good. I still cannot find an HSS drill bit in SDS fit.

Ah! I see what you mean - you want a non-masonry bit for a drill fitting that is generally designed for use with masonry.... Mmm. Don't think I've ever seen such a thing.

The only thought that arises (but I don't understand your needs!) is that you can get adaptor chucks.

 

[lanham]

Yes, I can get an adapter chuck for about £15 from Amazon. Looks like I will have to do that. No wonder I cannot find any, they don't exist.

Thanks for you input though

A bit cheaper? http://www.toolstation.com/shop/Pow...400/Keyed+Chuck+with+SDS+Adaptor+&+Key/p56617

I don't know what yours is like, but my SDS+ is so big and heavy that I wouldn't contemplate using it for anything but concrete and brick.

 

[lanham]

Cheaper? that's almost a quarter of the price. Cheers. I have only got a Bosch which weighs about 2.2Kg.

You can get SDS shank auger bits, but to date all the ones I've seen are carbon tool steel. In fact most drills for wood are carbon steel for the dual (and very good) reasons that carbon steel is far easier to sharpen than HSS and hones to a far superior (i.e sharper) edge than HSS meaning improved cutting performance (smoother cutting). The best known HSS wood drills these days are the bimetallic "nail proof" speed augers by Armeg (Wood Beaver), Irvine (Blue Groove), etc which in the main have 1/4in hex drive shanks (for use in quick adaptor chucks, SDS bit holders and impact drivers, etc) and the lesser known ship's auger bits sold for boring through nail-infested timbers. The only ones I'm familiar with are made by Bosch and Makita and they require a 13mm conventional chuck. Speed augers are necessarily short as their principal use is for boring through beams and joists in existing buildings, etc. Ships augers are a lot longer. Either way the HSS tipped drills never drill as fast or as cleanly as equivalent carbon tool steel drills IMHO

Thanks, I have decided to buy a chuck to take my existing non SDS drill bits.

 

[lanham]

I bought the one from Toolstation, £4.56 can't be bad.

If it's branded Silverline then yes it can!

 

[lanham]

I can't see a brand name on it.

Why would you want to use a HSS on an SDS drill? You will find most SDS run @ 950RPM or just above, way to slow for metal drilling.
HSS are meant to run fast??? buy yourself a cheap parkside drill for 29 quid from lidl. it would do a better job at drilling metal or wood and keep your SDS for drilling masonry..
