770B 4" Drill Extension
770B 4"A combination of Extension Rod and interchangeable Collets.
A real precision tool for both machine and hand drilling..
RUGGED – Can be used in drilling the toughest materials such as titanium and stainless steels.
ACCURATE – Eccentricity of drill bit with respect to axis of Extension Rod is less than .002” T.I.R.
EASY TO USE – Dull or broken drill bits can be replaced in a few seconds – without removing
Collet from Extension Rod.
EFFICIENT & ECONOMICAL – Three Extension Rods accommodate a total of 81 interchangeable collets covering a range of drills from 1.55mm to 8.00mm, and are available in two standard
