Product description
AS SEEN ON THE TELEVISION SHOPPING CHANNELS THE LAST DRILL BIT YOU WILL EVER NEED TO BUY COMES COMPLETE WITH A LIFETIME WARRANTY........IF YOU MANAGE TO BREAK BLUNT OR DAMAGE ONE OF OUR DRILL BITS WE WILL REPLACE IT NO QUESTIONS ASKED One Drill bit drills all......instead of having one drill bit for Wood another for Metal ect ect you have one drill bit !! It doesnt matter if its Wood,Brick,Glass,Tiles,Masonary,Concrete, Metal,Steel,Stone The Drill All Drill Bits drill the lot and much more They stand heat ! unlike normal Drill bits when they get hot they dont go soft........The Drill All Drill Bits are Colbalt Tipped so temperature doesnt effect them so you can go on drilling different materials without changing the drill bit. Colbalt is what they use in Armor Plating and Gun Barrel because of the heat it stands.If your putting up a metal bracket and you hit a Concrete Lintal normally you would damage the Drill bit but not with the Drill All Drill Bits They work with or without hammer and at any speed although if drilling Porcelain orGlass you need to use coolant and drill at a slower speed EACH SET CONTAINS - 1 x 3mm,1 x 3.5mm,1 x 4mm,1 x 4.5mm,1 x 5mm,1 x 5.5mm,1 x 6mm,1 x 6.5mm,1 x 7mm,1 x 7.5mm,1 x 8mm,1 x 8.5mm,1 x 9mm,1 x 9.5mm,1 x 10mm

When they arrived I saw that the bits had a "spade" shaped end that was about 1mm larger than the actual drill shaft - a bit like a normal masonry drill.
My first use was to drill some 6.5mm holes in some soft wood (pine or deal) and some 1/4 inch plywood. The drill seemed to take much longer to go through than I expected, with a fair bit of smoke from the wood. The resultant hole was very "fluffy" around the edges and the drill broke through with a fair bit of splintering of the rear of the wood. I wasn't particularly bothered as it was not critical for the job I was doing but clearly some sort of support backing is essential to achieve a clean exit hole. When I tried drilling a 10mm hole in some hardwood (Iroko) a neat clean hole was essential as I wanted to insert a dowel plug. However the sides of the hole were again "fluffy" and imprecise and the dowel did not fit tightly. I had to resort to normal tungsten-tipped-steel drill bits to complete the job where the finished appearance was all important.
My second experience was trying to drill 4.5mm holes in a cement screed floor to take "rawl-plugs" to screw down carpet fixing battens. I tried a high speed without hammer action (as recommended in the instruction DVD) but the drill made virtually no impression on the cement. I have had difficulty drilling this same floor in the past using standard masonry drills but have managed it by using hammer action; albeit trashing the drill bit in the process. As non-hammer didn't seem to work with the Drill-All I tried the hammer action but it just made more noise with no more progress. I resorted to non- hammer and tried just pressing a bit harder. The result? No hole in the floor but a totally burned out, so called "Drill-All" bit (which was now about 7mm shorter than when I started). I tried the 4.0mm bit and got exactly the same result - bit burned out but only a shallow depression in the cement floor. In the end I did the job by the old, tried and tested conventional masonry bit + hammer action. Job done - three holes drilled one (40 pence) masonry bit wrecked.
I then decided to do a "bench test" on the "Drill all" with a variety of materials.
1) Formica faced chipboard (worktop) :- drilled okay but nothing spectacular - chip board smoked a bit. Seemed to take quite a long time compared to conventional bits.
2) Soft and hard wood: - as per my previous experience with these materials - fluffy imprecise holes and apparently quite slow to penetrate all the way through, some smoking, broken wood fibres around exit hole unless supported by tightly clamped backing material, especially with the softwood.
3) 4mm thick mild-steel bar:- for this test I used a new 5mm conventional HSS drill bit. Without any dot punching and without skating around, quickly and cleanly cut through the bar in 11 seconds, removing a neat spiral of swarf. By comparison the (new and unused) 5mm Drill-all skated about all over the place before I could get it to even start cutting. I scratched a cross in the surface of the steel and managed to get the Drill-all to start biting. It took 36 seconds chipping out a pile of tiny rough metal chunks to cut through the bar. The resultant hole was visibly larger than that cut by the HSS drill bit - I measured it to be just shy of 6mm - hopeless for any precision work.
4) Engineering brick. Without hammer action the 6.5mm Drill all made a hole in the engineering brick but took a long time. I didn't have a 6.5mm masonry bit so used a 7mm. Without hammer it seemed to make similar progress to the Drill-all but was obviously getting a bit hot (un-lubricated). When I switched to hammer action the conventional masonry bit was much, much quicker.
5) Ceramic tile & glass. These were the only materials where the Drill-all out-performed conventional bits (HSS, Masonry and Tungsten tipped) cutting slowly but cleanly through both materials without any difficulty on a slow speed and with a simple cooling lubricant (just water).
Fortunately Ideal TV have replied to my complaint email with a free return for refund or replacement. I will be asking for my money back - this is better than the 10 year guarantee from the wholesaler, which requires you to pay £4.95 postage for replacement of your purchase (in addition to the cost of posting the broken bits back to them!).
Conclusion:- At £40 these Drill-All bits are very over priced and do not do anything like the neat efficient job of, much cheaper, conventional drill bits. Unless you want to regularly drill ceramics or glass they are a total waste of money. They are a complete misnomer and ought to be called Drill-Bu**er-All !!!!
Do NOT buy!
i think the demo people use different special drills
These are being sold on a tv shopping channel and the demonstrators are obviously cheating when they appear to drill various materials including hard steel.
I would warn any prospective buyer to avoid these at all costs and stick with a good quality standard HSS drill bit.
