Drills & Notching Blades
(last updated 12/17/2007
)
Generally-available,
heavy-duty, off-the-shelf
drills are used to allow easy replacement or repair should they ever fail. All of
the following drills (except for the Black & Decker) have ball-bearing
chuck-end bearings. They all have a 0-2500 RPM speed. Refer to the
"Products" page to order and for other information.
[Black & Decker]
[DeWalt] [Hitachi] [Makita] [Notching
Blades]
Question: Which
notching blade should I use--the fine-tooth or coarse-tooth?
Answer: We ship the
machine with both styles but the coarse (60T) will work with both steel and
aluminum armor while the fine-tooth (132T) can clog with aluminum but is less
"grabby" when cutting steel. More info on these is below.
Question: Why don't
you use Milwaukee drills to match the Milwaukee saw?
Answer: There are no
Milwaukee drills currently made that will fit into our existing drill frames
without major modification. As time permits, we may develop a way to mount
Milwaukee drills into our machine.
Question: I
snapped-off the right drill arbor trying to take the nut off to change the
blade. Who tightened this thing?
Answer: We
hand-tighten both right and left to about 20lb-ft which is a little past
"snug". What happened was that you turned the right drill nut
CCW to "loosen" it when in fact you were tightening it because it is
LH (backwards) thread. Brute strength overcame cold steel... The
right-side is LH so the nut won't loosen-up due to blade rotation. Also
note that the arbor is pinned for that same purpose. We now also stamp an
"L" into the end of the LH arbor. Everyone in your company who
will be using the machine should read the directions before using or servicing
it.

The Black & Decker DR450
3/8" VSR drills (4A, 4.5A, 5A) we had used for 3-4 years have long
since been discontinued. We have a very limited supply available if you want
or need a spare. These drills
have been very reliable and seldom needed replacement. These also have a
sleeve-type chuck-end bushing which has never been a problem. The
picture above shows a returned, "warranted" drill which we tested,
installed a 1/2" chuck and "spare" DeWalt cord and it has
been working flawlessly for us for over 3 years. It is one of several
B&D shop drills that were warranted but are still very serviceable.
Parts are readily
available from Black & Decker should you need service parts. UPDATE:
We still have a few of these drills brand-new in stock and are
looking to close them out. When we discovered they were being discontinued,
we bought out every last one of them in the country, over 100 of them! If
you have a machine with these drills in it, be sure to order a spare today
because once they are gone, THEY ARE GONE and you will have to retrofit
another model drill which could prove inconvenient or costly...

Sometimes these can be repaired by blowing the grit out
of them and running them opposite of their normal rotation for a minute or
two to "clean" the glaze from the brushes. You can
also adapt any of the following drills.

As an optional heavier-duty
replacement for the above, we developed a kit to install DeWalt DW106
3/8" VSR drills (5.4A) into our machine. See the updated Order
Form (Word 95 file, orderform.doc, 23k) for ordering info and kit
description. This was to be the replacement drill for the B&D when
we ran out but has been since been discontinued by DeWalt. They are
readily available Remanufactured or in used tool/pawn shops. The kit
should also work with any other DW10x models. Refer to the above
picture of a shop drill (not a warranty return). The second picture shows
drills mounted in a machine. The third picture shows the kit mounted under
the belt hook of the drill.

Another drill that can replace the B&Ds are the Makita 6408 3/8" VSR
drill
(4.9A). These are a very well-designed, heavy-duty drill and should
provide years of service. Since they are more expensive and require
considerably more labor to fit them into the machine, the price of the MC
Cable Cutter & Pigtailer will increase if you want these optional
drills. Our sources say that there are 1000s of these in the
warehouses so this will be one of the drills we use for the next few years.
You would really only want or need these installed in your machine if your
tool room prefers/services Makita tools.

The latest standard drill we will be
using is the Hitachi D10VH 3/8" VSR drill (6A). These are a very well-designed, heavy-duty drill and should
provide years of service. There are 1000s available and this will be
the standard drill until further notice. Although imported, the fit
and finish of this drill are top notch. In the 2 years we have been using
these in our machines, we have yet to have any warranty problems or returns.

As noted above, the coarse, 60T Notching
Blades work with both steel and aluminum armor MC. They are
black-oxide coated with a slight kerf. These will last indefinitely
when cutting aluminum. Click the thumbnail on the left below for a
better look.

Also able to cut both steel
and aluminum and shown on the above right is the fine, 132T notching blades,
although these may clog when used with aluminum. They are
precision-ground and hardened and are specially made for our machine.
These cut a little smoother than the coarse and have less tendency to
"grab".
Left and Right replacement
arbors and hardware can also be ordered. Refer to the Price List for
price and availability.

In a pinch you could probably
adapt a different "no-name" imported drill but we have not done so due to
product quality and configuration variances...(ie: from a tool show, Harbor
Freight, etc.)
