## Description

Drill America #34 x 6" Cobalt Aircraft Extension Drill Bit, GLBCO Series : desertcart.in: Industrial & Scientific

Review: I bought these for teenagers to work with on a robotics team, they take plenty of abuse by kids learning to work with tools. Will absolutely buy more of these as needed.
Review: This drill was perfect for my project. I was rebuilding a transmission and had to replace the output shaft sleeve, that needed 2 holes drilled but needed to be extra long to do so.

## Features

- Effective in drilling tough, high tensile strength materials like stainless steel, inconel and titanium
- 135° split point tip prevents drill from walking
- Round shanks allow use with a wide variety of tool holding systems
