Description of Jobber Carbide Tipped Standard 50360
0.136" diameter carbide tipped jobber length drill 118° standard point. 1 3/4" length of flute. 2 7/8" overall length. #29 size. Tool Diameter Tolerance: +0"/-.0007". Used by machinists and hobbyists for general purpose drilling of most materials.
Looked good quality when received, came in its own tube and had cosmoline (?) or some sort of wax to protect the tip. Allegedly made in the USA. I used it to drill holes in the bottom of the car's cast iron intake manifold to use long #7 3/8" screws to attach the oil slinger. It broke on the 5th hole so I had to try later to remove the hardened steel piece from the cast iron. Not easy. Very disappointing.
