Extra long drill is a high performance deep hole drilling without coolant through, which is the 1st drill to process deep holes 15X diameter, without pecking and without the use of internal coolant supply. Flute form, point thinning and compound lead construction are all patented technologies developed by OSG to make this drill do what no other parabolic HSS-Co drill can. The addition of exclusive WXL coating technology makes non-peck drilling repeatable, even in the longest of production runs.
