The Ocean Penetrator is a taper shank twist drill bit specifically designed for fast
productive drilling of structural steel profiles with CNC beam drill lines of all types.
The drill features a chip breaker design that quickly breaks off the chips into small manageable
pieces and avoids the long stringy chips that normally plague drill lines.
The Ocean Penetrator drill bits feature oil coolant holes that run through the drill bit
to cool the center of the drill while it is drilling through all structural steel profiles including
beams, channel, angle, plates, tube, etc.
This results in exceptional tool life. Our customers average anywhere from 300 – 500 holes
per sharpening1 and are able to get more than 100 sharpenings per drill bit. This
yields in excess of 30,000 holes per drill bit resulting in significant savings and improved
overall fabricating profitability.
The Ocean Penetrator drill bit is now also available in a Cobalt coating2. This
further improves the drilling speed, increases the number of holes that can be drilled before
resharpening, and increases your overall profitability.
 We
are also now able to supply the Ocean Penetrator drill bits with a factory sharpened 170 degree
drill point3 as opposed to the standard 135 degree drill point. To obtain the best
performance the drill must be sharpened to a 170 degree drill point geometry. This is ideal
for structural steel and results in burr free holes that further reduces costs by eliminating
the costly grinding of the exit hole.
The resharpening of the drill bits is a simple one-step process on the Rush 250 A drill grinder
available from AJ Machinery. The operator is able to easily resharpen drill bits in less than
2 minutes and this is normally done while the CNC drill line is running, meaning that the drill
resharpening is done during operator idle time.

This further translates into further efficiency as the drill chips and swarf compress to
occupy much less space in your scrap bin than the stringy chips which fill the bin with air
Ocean Penetrator Drill Bits - Benefits
-
Much cheaper than mag drill annular cutters. Reduces the consumable cost from approximately
20c per hole to less than 1/2c – this is 4000% reduction in drill bit costs compared to
mag drill cutters
-
Much cheaper to run than insert drill bits (approximately 10X cheaper than insert drill
bits)
-
Simple to re-sharpen – only 1-step process. New 170 degree point further simplifies sharpening
process
-
Faster feed rate = shorter drill time = faster production. A 213/16” diameter only takes
7 seconds to drill through 3/8” steel.
-
Eliminates grinding of exit hole
NOTES
1. Actual tool life will vary based on a variety of factors including drill diameter,
thickness and hardness of material being drilled, drill RPM, drill feed rate, drill sharpening
quality, and other factors.
2. Cobalt coating not available on all drill diameters
3. 170 degree factory drill point not available on all drill diameters
