Vyrobené z HS ocele a brúsené do bodu 118°. Tieto vŕtačky rozširujú rozsah veľkosti prenosného skľučovadla. Spoločná drážka a celková dĺžka pre minimálne nastavenie pri výmene nástroja. Presné brúsenie pre vysoký stupeň sústrednosti medzi stopkou a priemerom tela. Ideálne na vŕtanie do materiálov s nízkou a strednou pevnosťou v ťahu. Čierny a svetlý povrch.

Pri chode proti smeru hodinových ručičiek (pravý rez) špirálovito drážkované nástroje odvádzajú triesky hore a von z rezu, aby sa znížilo upchávanie. Okrúhle stopky umožňujú použitie so širokou škálou systémov upínania nástrojov. Ošetrenie čiernym oxidom dodáva mazivo a vytvára malé vrecká na povrchu nástroja, ktoré slúžia na zadržiavanie chladiacej kvapaliny v blízkosti reznej hrany. Nástroje z rýchloreznej ocele sú vhodné pre väčšinu aplikácií na všeobecné použitie a ponúkajú kombináciu tvrdosti a húževnatosti pre odolnosť proti opotrebovaniu.

I am sure there are much better quality and professional bits out there
I am sure there are much better quality and professional bits out there. But for the price, this one can't be beat. How often do you have to drill a 55/64" hole? If the answer is more than 12, maybe you should find a better option. For me, the three holes I needed this bit for came out nice and crisp. A little wobble from the extra large bit, but if you make sure your work is clamped down on the drill press firmly that can be eliminated. The bit itself, is made of quality steel and the flutes are sharp. I especially like how the edges are milled with a different type of metal, it made the three holes I had to drill come out nice. I cannot speak for the longevity of the product past that but, after three holes it was still sharp.

What can be expected for the price.

good bit.
I needed a hole, I got a hole. I will probably never use this again but only because i am not a plumber and don't need to do NPT fittings.

Doesn't cut it in a hand held drill.
I used this drill bit in a vehicle hitch install that required enlarging a small hole to 17/32. The frame was less than an 1/8 of an inch to drill thru and the bit couldn't handle it. Gave up on the bit.

All as expected
The drill dimensions and quality were "as expected". I used it to drill out a reluctant Allen pipe plug. It cut well.
