Have bookmarked them

I use a fair few of them 6mm SDS bits.

Ditto.


Well the first bit.

Question for those who know their bits (stoppit!) What's the difference between the different bit types? HSS, HSS Ground, titanium coated, cobalt? Presumably the more expensive the better.

But my cheap set from some DIY shed or other which has titanium coating seems to have gone blunt much quicker than my dad's set of engineering bits he's had for many years. Do they just not make them the same anymore, or are they so cheap just chuck 'em when they're blunt?

[Mike H]

Yeah once I got one of these special deal everything in it kits for peanuts, it's shite, like tried one of the wood bits, there was so much friction versus any actual cutting the wood caught fire!

HSS "high speed steel" good engineering metalworking drill but can be used for wood plastic etc, not sure about HSS ground maybe more accurate? cobalt is really hard and tough will drill through harder steels such as stainless, I've used one to drill out a high tensile bolt that a HSS drill wouldn't touch and it didn't blunten it at all expensive though (one 7mm drill cost me £6) but should last a lifetime if treated properly

Yes cobalt drills are great for stainless but not cheap.Basically,you get what you pay for.Don't buy cheap sets that claim to go through anything.They don't.It's worth paying the extra IMO,will save you money in the long run.

[simon]

Thanks chaps. So a 19 bit HSS drill set for £7.54 might be false economy? An equivalent cobalt set is £23.49, which is nearly 4 of the cheap sets. You pays yer money and makes yer choice I guess?

[Dave the bass]

All this drill-talk in't arf boring.

You don't love it to bits then?

[Dave the bass]

I don't see the point.

I don't know for certain, but I think how they are used affects life as well. I know when I can use my cheap drill stand it cuts a lot nicer and I suspect does less damage to the bit than when I have to use a hand drill.

The use of a cutting fluid will help any cutting edge last longer and improve the quality of cut even if its just a squirt of 3 in 1 although there are some proper cutting fluids available cheap if you do a lot of this type of work.
