D'Chicago-Latrobe 769 Serie riichtflüchteg Bohrbit ass aus Karbid mat engem onbeschichteten (hellen) Finish gemaach an huet en 140-Grad 4-Facetpunkt fir ouni Pilotloch ze penetréieren an d'Verstoppung op Goss ze reduzéieren, an net-ferro- an gehärte Materialien. Riichter Flöten bohren flaach an horizontal Lächer. Solid Carbide ass méi haart wéi High-Speed- oder Kobaltstahl fir besser Verschleißbeständegkeet ze bidden an d'Toolliewen bei héijer Geschwindegkeet ze verlängeren. Déi onbeschichtete Finish bitt eng onbehandelt Uewerfläch. De selbstzentréierende 140-Grad 4-Facetpunkt gëtt Kraaft an héich Genauegkeet fir Material méi einfach wéi e konventionelle Punkt ze penetréieren, a produzéiert kleng Chips fir d'Verstoppung ze reduzéieren. D'Ronn Schank empfänkt déi meescht Drill Chucks.Drill Bits si Schneidinstrumenter déi benotzt gi fir Lächer an enger Rei vu Materialien ze maachen mat Maschinnen wéi Handheld portable Drills, Machining Centers, and the lathes. D'Material gëtt zesumme mat der virgesinnen Bueraarbechten Déift drilling bestëmmen d'Längt an Stil vun Bueraarbechten, datt benotzt ginn soll.Chicago-Latrobe manufactures drill bits and accessories, reamers, countersinks, and blanks. D'Firma, gegrënnt an 1890 a mat Sëtz zu Clemson, SC, entsprécht International Organization for Standardization (ISO) Standard 9001.

Great bit for hard metals
I just had to drop a note to say how well this bit worked for me. I had a hardened steel shaft I was trying to cross drill that burned out or broke 3 HSS bits so I ordered this bit. Using my mini mill this bit went right through without any issues!

Like a Hot Knife Thru Butter in General, but Fluted Bit Broke Upon First Use
This #31 bit cut through a 1/2" diameter hardened steel shaft like a hot knife through butter. I tried a cobalt drill bit first, it would hardly make a dent. Update on the 769 Latrobe Fluted Bit, Size 15/64: I have many Chicago Latrobe drill bits, and except for this one, they are fantastic. I was drilling 1/8" thick Type 316 stainless steel with this 15/64" bit in my drill press, using Anchor Lube for lubricant. The flutes broke apart after approx 5 seconds of engagement. This type of stainless is very hard, and I needed to press down moderately hard with the drill press. My other Latrobe bits are spade and twist type, not fluted like this one. They hold up really well and stay sharp for a long time. Perhaps I was pressing too hard with this one, but I will stick with spade and twist type bits in the future.

Not as expected
The top label is what I ordered, the bottom label is what I received. It is still useful just not what I wanted exactly.

Best bit ever!
This bit saved me from having to go to the machine shop. After reading reviews, I decided to purchase to drill out a broken off bolt for a valve cover on a classic car. No other bits would bite into whatever was broken off(not sure if someone broke off an extractor or ez out before I got to work on it.) this bit started to work right away, drilled through it in no time. Worth the money!!

sharp and ridgid
will drill through work hardened metal. straight flutes are more shatter resistant than spiral flutes. clamp work for best results and use a mill or table drill. last resort, if you must use a hand drill set on lowest speed and set torque to slip if it grabs. carbide drills will shatter if work moves or shifts while drilling. these drills will hold an edge longer than hss or cobalt but break easier.

Worked when nothing else would
This is an amazing bit. Chewed right through exhaust bolts when NOTHING else would. I tried other carbide bits and they wouldn't even make a dent. This bit went right through. Don't forget to use some wd40 as not to overheat the bit and break it.
