Ideal for drilling in mild steels where extra length for reach is required. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow.

Good bits for the occasional time your standard bit is just a tad too short...I am slowly making a complete set of long drill bits for those times...so foar these have been good bits for aluminum and wood (have not needed to drill steel yet with long bits.....but that time is coming...lol)

Perfect size and length for drilling an oversized item in one go. Worked very well.

Every once in awhile regular drills can't reach deep enough to get a hole done , and this bit fills the need, and at a decent price too.

Longer than what I needed, but allowed me to access the area I needed to drill a hole in

This is one of several sizes of HSS drill bits I bought at the same time. An extra long drill bit is not often needed but when you need one, nothing else will do! I’m happy with these, drilling wood, aluminum, brass, and steel.

I needed a specialty bit for a project and this was exactly what the job called for. It worked as designed.

Good drill bit for wood work if used slowly. Works great for small projects.

When I’m drilling, it squeals super loud once I’m 4” in.. it happens alot to me.. good cheap bit for drilling them deep holes. Although even being slightly very careful , it bent jsut a little.. I only have 6.25” to work with so it wasn’t too bad.. my neighbors probably hated me.

Excelente broca, buen material, buen filo. Se comió las cabezas de unos tornillos dañados casi sin esfuerzo (para eso la compré). Por ser más larga de lo normal es excelente para alcanzar tornillos o remaches profundos en aparatos como bocinas o no-breaks.El único detalle por el que no le puse 5 estrellas es porque venía ligeramente comba (arqueada, curva), por lo que "cabeceaba" ligeramente al girar. Pensé que era el taladro pero al comprobar en una superficie lisa fue evidente que era la broca. Si quisiera usarla en trabajo de más precisión no me arriesgaría, pero para lo que la compré (quebrarle la cabeza a tornillos barridos) resultó excelente.
