"Due to the tip shape they center well and don't tend to drift when starting so the hole is exactly where you want it. They are fast to drill with but can leave untidy edges as the cut is quite aggressive."
"After struggling with and blunting other HSS drill bits to drill 11mm holes in 2.5mm steel even after drilling smaller pilot holes first, I decided to give this a go and WOW it drilled all the holes without the need for a Pilot hole with ease and is still sharp. For Metal I am not going to use any other Drill Bit"
"As a fabricator I've been drilling holes in steel for 25 years. I've just drilled around 600 holes in 10mm steel with one of these and the last hole was drilled just as good as the first, these are the best bits I've come across."
"I had to pre-drill literally well over a thousand fixing holes in corrugated steel cladding sheets on a massive job, which is obviously a serious test of any drill bit & was fed-up with the relatively short life & low performance (and associated aching muscles!) of 'standard' (albeit good quality) HSS bits, which weren't lasting very long.
I've used this type of drill bit before in the past ( I believe 'Piranha' / Black & Decker branded?) & like the self-centering nature of the bit, together with the very impressive drilling performance.
These Dewalt bits are equally as impressive as those I've previously experienced & their quick-starting without any wandering off-target feature is obviously a boon!
"I killed three different drill bits drilling holes in scaffold tubes. I read the other reviews on here and wanted to give it a try with this one. Brilliant - job done, drill bit still perfect. DeWalt drill bits for me all the way now."
"Bought a couple of cheap drill HSS drill bits, not from Screwfix, and they went blunt after a couple of uses drilling through only a couple of mm of metal. Following the advice of people writing these reviews I used 3 in 1 oil to keep the bit cool and took it steady when drilling, not adding too much pressure and it works a treat! Have been able to drill several holes so far and still going strong. The extra cost of the drill bit is well worth it."
"I bought 2 Dewalt drill bits, a 5mm & 6mm for drilling into 3mm metal, I have just got to say how fantastic these drill bits are for the money, they didn't skid of the metal at all. I would recommend anyone wanting to drill through metal with ease to use them. They are a stock item too which was a bonus. I wasn't expecting much for the price, but I am very, very pleased with the outcome & will certainly buy again."
