flintronic Step Drill Bit 5mm-35mm, with 1 Automatic Center Punch& 1 Twist Drill Bit, HSS Titanium Coated Double Slot Cone Cutting Drill

I got it today and used the centre punch and drill bit, which fitted in my smaller cordless drill...the step drill bit however did not fit my smaller cordless drill so I had to use my bigger cordless drill.. Be careful that you have a larger drill or else the step drill bit will not fit in .Apart from that it bored through my galvanised steel incinerator bin with no issuses, all three bits worked fine..not sure when i will use them again tho so cant vouch for durability over time

Delivered next day prime. Bought to make holes to a extant only thing is the larger cone cutter didn't fit dill so come up stuck there, maybe require the smaller size ones.actually the alloy steel looks durable and would allow fir faster cutting and impact resistant. Handy in moderation.

I used this tool to bore a total of ten 22mm holes in mild steel. I used a bench pillar drill on its slowest setting. Whilst drilling I used plenty of cutting oil to keep the tool cool. Due to the thickness of the steel, I drilled about halfway through then turned the metal over. The tool is still sharp and perfect for further work.

As described works well

I suppose you get what you pay for. Should have read the reviews first. Whilst this seems decent-ish quality, its obviously a cheap product from China and the diameter of the bit doesn't fit in a standard drill. I only wanted it to drill a hole in a water butt so couldn't justify the cost of branded step drill bits, hence buying this. The drill bit is useless unless I buy a heavier duty drill. Still, the centre punch will come in handy I suppose.

metal was very poor was blunt after just one basic cut, so because of this i can not recommend anyone purchasing this item.

The cone cutter does the job I need it to and the automatic punch is a bonus in this purchase. Not sure about the drill bit. The drill bit works ok but the rasp type shank is debatable. Overall pleased with purchase.

Product delivered as described on time and fit for purpose

Başarılı

Per ora ho utilizzato solo la punta conica di dimensioni minori. Sono riuscito facilmente nel mio intento di allargare un foro (spessore piatto 3 mm) e la punta è ancora come nuova. Deduco che anche il resto del set sia di ottima qualità.

Bon et à prix raisonnable

Matige stappenboor. Snel beschadigd. Voor koper wellicht beter. Maar voor staal niet echt bruikbaar.

Ich habe die HSS Stufenbohrer für einige DIY-Projekte verwendet und bin mit seiner Leistung sehr zufrieden. Die Qualität des Bohrers ist ausgezeichnet und er hat bei jedem Einsatz präzise und saubere Löcher in verschiedenen Materialien erzeugt, einschließlich Metall und Holz. Ich schätze die Vielseitigkeit des Stufenbohrers, da ich jetzt in der Lage bin, Löcher mit verschiedenen Durchmessern mit nur einem Bohrer zu erzeugen, anstatt mehrere Bohrer wechseln zu müssen. Der Bohrer ist robust und hat eine lange Lebensdauer, so dass ich sicher bin, dass ich ihn noch viele Male verwenden werde. Ich schätze auch die klaren Markierungen auf dem Bohrer, die es mir leicht gemacht haben, die gewünschte Lochgröße zu wählen und präzise zu bohren. Insgesamt bin ich mit dem HSS Stufenbohrer sehr zufrieden und würde ihn jedem DIY-Enthusiasten oder professionellen Handwerker empfehlen, der auf der Suche nach einem zuverlässigen und vielseitigen Bohrer ist.
