Bosch HSS-Titanium 2607019436 Plastic Drill Bit Set (Multicolor, 13-Pieces)

Genuine product. Quality is good as expected. Box is also made of metal so will be durable. According to my past experience smaller bits below 4mm are not good for metal drilling and will break easily when pressure is applied. They are best for plastic and wood. However bigger bits can be used to drill into metals. But don't apply too much pressure while drilling. Apply only adequate amount of force according to the bit size otherwise bits can break. Usually they drill easily with adequate pressure. Don't forget to use oil to avoid overheating.

Nice product

Have broken fiw bits earlier while drilling through steel sheet 2mm, got replacements from local store, which also weren't upto the task either. These bits however, are one of the best out there, was able to drill multiple holes in no time and with such ease as if it was cutting through butter.

Nice product

Started with a thin bit to drill a hole and increased bit thickness, went through a steel tube easily, time will tell how long bits will last, it’s a good buy 👍

Pls don't buy, its fake. It breaks often while drilling on soft wood also

The bits are titanium coated . These are really sharp and it appears the coating does a good job of heat dissipation. Often ,after overheating bits tend to lose their edge. Have used a small diameter bit very extensively and it is still as good as new. So guess the bigger diameters should last a lifetime 😂Full sizes and a neat metal box with catalogued sizes.The very best bits out there

Locking wystem is very bad

No es el top de los tops pero, para un uso ocasional, cumple con su función. La caja metálica es un punto a su favor.

Wish I could return this. Sent it to Barbados for my brother and he says they're next to useless. Shame.

vorweg die bohrer sind klasseein stern abzug gibt es für die fehlende gebrauchsanweisung ? zu finden nach vielen suchen auf der bosch seite.-diese metallbohrer sind nicht für Alu geeignet !-desweiteren sind die bohrgeschwindigkeiten zu beachten: je kleiner der bohrer desto höher die geschwindigkeit
