The Ocean Clipper CNC Angle line
utilizes one drill and one punch, and therefore you will
need to resharpen drill bits. Fortunately resharpening
drill bits is a simple and easy process even fore
inexperienced operators, and the videos below are
designed to make this process even easier.
While a punch and die set might provide
5000 impacts before the set needs to be replaces, a good
quality drill bit such as the Ocean PENETRATOR Cobalt
drill bit can easily yield 500 holes or more per
sharpening, and over 50,000 holes from a single drill
bit, making the consumable cost of your angle line even
cheaper than a double punch setup.
Sharp drill bits make a huge difference
on your Ocean Clipper Angle line (as do fresh punch and
die sets). The difference between a sharp drill bit and
a dull drill bit, is night and day.
We have two different approaches to sharpening twist
drill bits.
A. NEW video - for Ocean PENETRATOR drill bits (simple
1-stage sharpening)
B. OLD video - for Nachi or Cleveland drill bits
(complex 2-stage sharpening)
If you have never tried the new Ocean PENETRATOR
Drill bits we suggest you give them a try. These new
drill bits.....
-
Are much faster to sharpen (only one
process)
-
Require a faster feed rate (approx
20%) and therefore drill faster than regular twist
drill bits
-
Eliminate long stringy chips that
fling off the spindle, and take so much space in the
chip-drawer

A. NEW DRILL SHARPENING VIDEO - For OCEAN PENETRATOR
Drill Bits
This new video has been specifically
created to assist operators in sharpening the NEW
Ocean PENETRATOR drill bits. These drill bits
feature a chip breaker design that eliminates the long
stringy chips, and allows faster cleaner drilling.
The special design creates a narrow web, and this
eliminates the complex sharpening that is required with
regular twist drill bits.

Drill Grinding Tips
-
We recommend you switch out your
drill bits before they get dull, that way you will
only have to do a light dressing / resharpening to
get them back into service. If you wait too long and
continue to use them while they are dull, you will
have to spend more time on the grinder doing the
resharpening.
-
Tell tale signs that your drill is
getting dull include.....
-
The drilling time per hole starts to
increase
-
Steam starts emanating from the tip
of the drill bit
-
A blue color starts appearing on the
chips / curly cues / discs
-
A blue color starts appearing on the
cutting surface of your drill
-
A harmonic noise/vibration starts
emanating coming from the drill bit
-
You should get approximately 300
plus holes per sharpening. Of course your own actual
mileage may vary considerably from these numbers.
-
You should also adjust your drilling
feed rate on your Ocean Clipper Angle Line to get
the best compromise between drilling time and the
number of holes drilled per sharpening. Increasing
the feed rate increases the amount of metal removed,
but reduces the number of holes per sharpening.
B. Drill Sharpening Tutorial Video for Regular Twist
Drill Bits
The Ocean Clipper can be supplied with a
Rush 250A Drill Grinder if you don't already have a
drill grinder. The drill Grinding Tutorial Video below
will show you how to sharpen your drills and achieve the
ideal drill point geometry for Structural Steel, using
the Rush 250A.
The video below pertains
to standard (non chip-breaker) twist drill bits such as

IMPORTANT - Please note the following
In the video (at 2mins 13 secs), we make
mention of the front clearance relief angle selector
where we say that this setting should not change - This
is incorrect - please consult the manual supplied with
your drill and adjust this setting according to the
drill diameter
Follow the directions in the video -
adjust the center point height to suit - too flat and
the drill will not center well - too high and the drill
point will wear too fast.
All Rush 250A drill grinders supplied after July 2004
have a steel wheel with diamond abrasive coating. The
diameter of this wheel does not change - of course the
coating wears out and the wheel has to be replaced
periodically, depending on the amount of drilling and
sharpening you do. Because the wheel diameter does not
change all settings remain constant for each drill
diameter. If you have an older style consumable abrasive
wheel, the diameter will change with time and all
settings must be adjusted accordingly.
You can achieve great drill performance using several
different approaches to drill grinding. We recommend
that you experiment with your own approach and narrow
down your own style of drill grinding. Drill grinding is
as much an art as a science.
You should also adjust your drilling feed rate on your
Ocean Avenger Drill Line to get the best compromise
between drilling time and the number of holes drilled
per sharpening
If you are using Nachi or Cleveland drill bits you will
need to complete all 3 steps in the video, to create the
1. raised center point,
2. relieved heel, and
3. thinned web
NOTE: With the NEW
Ocean PENETRATOR Drill bits you only need to do the
first step. The narrow web of the Ocean PENETRATOR drill
bits makes web thinning and heel relieving obsolete and
significantly shortens the time to sharpen the drill.
Drill Grinding Tips
-
We recommend you switch out your
drill bits before they get dull, that way you will
only have to do a light dressing / resharpening to
get them back into service. if you wait too long and
run them while they are dull, you will have to spend
more time on the grinder doing the resharpening.

Tell tale signs that your drill is
getting dull include.....
-
the drilling time per hole
starts to increase
-
steam starts emanating from the
tip of the drill bit
-
a blue color starts appearing on
the chips / curly cues / discs
-
a blue color starts appearing on
the cutting surface of your drill
-
a harmonic noise/vibration
starts emanating coming from the drill bit
-
Once you have done a complete
sharpening of the drill bit as per our video above
(i.e. grinding the cutting face, relieving the heel
and thinning the web), you will be then be able to
get approximately 10 LIGHT DRESSINGS of the drill
bit primary cutting surface before you need to do a
complete sharpening again.
-
You should get at least 300 plus
holes per dressing, and 10 dressings per complete
sharpening, giving you approximately 3000 holes
before you need to relieve the heel and thin the web
again. Of course your own actual mileage may vary
considerably from these numbers.
-
You should also adjust your drilling
feed rate on your Ocean Avenger Drill Line to get
the best compromise between drilling time and the
number of holes drilled per sharpening. Increasing
the feed rate increases the amount of metal removed,
but reduces the number of holes per sharpening.
