Drilling
U15A - AIRCRAFT JOBBER DRILLS.
PARALLEL SHANK. ANSI LENGTH. M2 HIGH SPEED STEEL 118 SPLIT POINT. NAS907B
These tools are not routinely stocked (U15M type in M42 8% Cobalt being preferred, and serviceable for more purposes) but can be provided to special order. Flute and overall length data are exactly as per U15M.
A very comprehensive range of jobber drills in M2 HSS, but to the slightly different European lenghts (BS122/DIN338) can be found in the standard TRUBOR range, No.150A series.
