Aircraft Extension Drill
This Cleveland Golf C13198 is an extra-long drill bit designed for aircraft maintenance and deep-hole applications. It suits mechanics and fabricators who need extended reach in metalworking tasks. The high-speed steel construction supports demanding machining operations. It is not for buyers who need coated cutting edges or shorter jobber-length bits.
Practical limits of the HSS uncoated interface
The bright uncoated surface performs well in general-purpose steel and alloy drilling but wears faster in abrasive or high-heat materials. The 135-degree split point aids self-centring yet requires rigid setups to prevent deflection at full 12-inch extension. Maximum drilling depth is 1 5/8 inches per pass. It is not for production lines needing coolant-fed or carbide-tipped tooling.
13/32 inch fractional diameter decides fit
The 13/32 inch fractional size determines compatibility with specific bolt clearances and rivet holes in airframe work. The 4xD proportion and 21 to 34-degree helix range control chip evacuation in deep cuts. Verify the exact fractional diameter against your drawing before purchase. It is not for metric-only hole patterns or tapered reamer preparations.

Questions about this item
Should I choose the 13/32 inch size or a different diameter?
This bit is 13/32 inch diameter and 12 inches long; pick it when the hole must be that exact fractional size and reach.
What does the 135 degree split point do in a real machine?
The 135 degree split point centres quickly on metal and reduces walking, so the bit starts cleanly without a centre punch.
What standard governs the shank and what does it cap?
The straight round shank fits standard 1/2 inch or larger drill chucks, capping the maximum chuck size you can use.
