Note the advantages associated with Superior Gundrilling.

Required tolerances and surface finishes are secured in one pass, with a penetration rate equal to or better than that of conventional drilling methods.
De burring, reaming, honing, work hardening and other secondary steps are eliminated. Results: less set up, no extra tools needed, which saves you time and money.
Cast iron, aluminum, brass, molybdenum, steel, heat treated stainless - and many other materials ordinarily too tough to drill - are easy drilled.
Precision holes with a depth-to-diameter ratios much greater than those obtained by traditional methods. ID tolerances to +/- .0005 inch, with 16 micro inch finish possible.
Holes from .055 to 1.062 in diameter - up to 28 through depth are held to specifications throughout a production run.
We achieve straightness to .001 per foot of depth concentricity to .001 /1 T.I.R. and better.
We perform difficult drilling operations: angular and flat bottom geometries angular, round or curved surface entry, overlapping holes, holes in stacked parts, multi-diameter holes, cross holes.
