HSS Cobalt Drill Bit 14mm Reduced Shank Twist Drill Bit for Metal, Stainless Steel, Aluminium, Wood, Plastic, Non-Ferrous Etc.

Good quality good price

My preferred drill bits that I use at home are cobalt ones, but they only go up to 13mm so this 20mm one was a good addition to the set.I’m very pleased with its performance, and it cuts stainless steel very well. What you get in the plastic tube is exactly what’s shown in the seller’s picture. There is a good coating of anti-corrosion oil on the drill, and it arrived in perfect condition.The shank is 10mm diameter and 55mm long. Overall the 20mm bit measures 150mm end-to-end. I will definitely buy more of these bits in different sizes when the need arises.

After using this drill bit on aluminium and mild steel it seems to be pretty decent for the price, it cuts nice clean holes without too much fuss and so far isn't wearing out so hopefully should last a good while before needing sharpening and replacing. I used it with a bench drill press and a couple of different cordless drills and it works fine with all.

It will drill metal & wood. The 16mm drill that I have will be ideal for fitting 15mm copper pipe.Very good quality steel. We used to call the drills, blacksmiths drill bit because they will fit in smaller chucks saving me getting out the big drill. Price is not cheap but if you require a quality drill you unfortunately have to pay for it.I did like the fact that it came in its own plastic container.

Nice quality, seems well machined and drills on centre as expected.I've had no issues with this drilling alloy and mild steel, so it does what it says on the tin.The drilling I've done has been lubricated and the bit seems to be holding an edge fine, so I'd say it's up to the job.No complaints.

Looked like it had been kicked around on the floor. It's not cobalt, cobalt-based alloys provide superior corrosion resistance And it's not marked with the abbreviation "co" for cobalt it just reads HSS. I wouldn't waste your money

A chonker of a drill bit (I got the 20mm version), appears to have been machined well and very solid and sharp.Laughed at the jobs I've used it for, though you don't want to be trying to use it for anything deep as it's quite "stubby" in that respect.Good tip on it has started through metal, plastic and wood equally well and it's far better than a spade bit of equivalent size for the softer materials.

The 'Meccion HSS Cobalt Drill Bit 13mm Reduced Shank Twist Drill Bit' arrived in a standard drill case.The only marking on the drill is '13.0HSSM2A' obviously the '13.0' is the diameter, whether this relates to a cobalt drill I cannot confirm. The pictures in the product description show drills with markings that contain HSSCo.The 13mm drill cuts 5mm thick mild steel, which is what I needed it for, but how long before it lasts only time will tell.

Ho provato ad allargare un buco su ferro ma dopo un'ora il risultato è stato nullo.

Utilisé sur un tour à métaux ; outil précis dont l'affûtage tient à la coupe.

👍👍👍👍👍

Dieser Bohrer hat nicht nur das Minimum erfüllt: Scharfe Querschneide und Abtrageschneide in verschiedenen Winkeln.Darüber hinaus gehend findet nan zwei Schliffe für die Bohrspitze um Reibung und Erwärmung zu reduzieren, die Spanaustreibung entlang der Spirale wird an einer scharfkantigen Schneide geschnitten die separat geschliffen ist und der Bohrkötper dahinter ist nochmal geschliffen und verjüngt, so dass es im Bohrloch weniger Reibung und mehr Platz für Kühlmittel und Abrieb gibt. Was beim Bohren in dickem Material sehr willkommen ist.Ich sehe hier mindestens 5 Bearbeitungsschritte mehr als bei anderen Metallbohrern.

Pas de problème ça coupe.
