Forged block of die steel 167 long (6,574mm) weighing 11,200 lbs (5,080 kg). Produced eccentric precision blind bore 7.750 +/-.002 dia x 163 deep (196.9 +/-.05mm x 4,140mm) with custom low stress radiused bottom hole profile. ID positional tolerance within 0.035 (0.89mm) through out entire depth of bore.

Thin-wall honing: Aluminum 6061 tube, 6.315" ID x 97" long. Wall thickness of 0.0425.

718 Inconel precision tube drilled from solid. 0.27" OD x 0.21" ID x 42.0" LG. Customer's project only needed a small volume of tubes and a dedicated tube mill production lot was too expensive and lead time was too long. Making from solid was the quick, easy and inexpensive solution.

718 Inconel precision tubing drilled from solid. 0.44" OD x 0.34" ID x 42.0" LG. Quicker, easier and less expensive than a dedicated tube mill production run.

Precision tubular blanks for non-magnetic drill collars.

Multiple deeply recessed sensor ports.

Drilled keyway feature for orientation alignment deep inside a non-magnetic drill collar.

718 Inconel tube x 120 long with 0.156 hole through the length of the part.

14.5 OD x 152 long alloy steel (3,100 lbs) with 28 0.250 dia holes through the length of the part.

A large diameter well head component with several 100XDia depth holes.

Not all drilled bar has to be round. Here is an example of when a customer's design requirement was best met with square bar. 4140 material 1.38 square bar and we drilled: 0.438 ID through in 144 long piece and 0.688 ID through in 96 long piece.

Pressure housings for downhole instruments in high pressure wells. The design intent is to have the smallest possible OD size for a given ID size which requires extremely uniform wall thickness to avoid collapsing under high pressure downhole conditions.

0.500 OD x 28.00 long part with 0.375 ID through the entire length.

Two 4140 piston rods with 2" ID and 2.25" ID drilled 83" deep. Each piston rod weighed 3,235 lbs pre-drilling.
