Our MAGCHECK™ was designed to be fast and
easy to use. Two separate magnets make it simple to inspect around corners
and in hard-to-reach places such as the main line area of an engine block.
Inspecting cylinder heads with these powerful permanent magnets is quicker and
less complicated than using a yoke-type magnet. MAGCHECK™ magnets can be
moved individually with one hand while you are shaking the powder with the other
Quick Air is an inline blowgun. It
installs between your air hose and coupler. Install a Quick Air and you'll
never again waste the time to disconnect the power tool from the hose just to
attach a blowgun. It is one of those small tools you can find in life that
once you use it, it makes the job easier and nicer and you don't know how you
did without it before! This blowgun is OSHA compliant.
LNS' drill stops are used to control the depth of the lock hole patterns and for controlling the depth of the drill hole when installing the stitching pins in blind holes. By allowing the drill bit to only penetrate to a predetermined depth, many common drilling errors can be avoided. Drill stops will help you drill precision holes and break fewer drill bits.
The Pin Spacing Drill Jigs are
used to create the best spacing for the pins. These jigs are most often
used on cracks longer than one inch. When repairing cracks in cylinder
heads or any other short crack, pins are usually installed one at a time
starting at the bottom, or one end of the crack, and working toward the other
end, drilling, tapping, and installing pins. A Pin Spacing Drill Jig will
help you drill holes on semi-flat to flat surfaces using the three step
method. Drill the first hole free hand, place the locating pin of
the jig into the drilled hole and drill the second hole. Next, move the
locating pin to the second hole and drill a third hole on the crack. This
is repeated throughout the entire length of the crack. Tap and install the
pins into the first series of holes. This same procedure is repeated three
times or until the entire crack is repaired leaving no spaces remaining between
the pins. This method is much faster than one at a time primarily
because of the time saved in changing tools. Some of the other benefits
include using fewer pins, more precise placement of the pins, straighter holes,
less grabbing of the bit as it breaks through and no spaces left between the
Broken taps can be very difficult to
remove. A tap extractor will work about 25% of the time. It is
important to remove any loose pieces before attempting to use a tap
extractor. If you have drilled the hole all the way through the casting,
it is often possible to drive the broken tap piece through the casting wall with
a punch. Sometimes it is helpful to drill another hole on the crack next
to the broken tap, and drive the broken piece out. You can then drill and
tap again and install pins to fill the holes. The best solution is to not
break taps. For further information see Tapping
Tips and Technical Support.
Trim-Kut® 3" grinding discs really
come in handy in finishing your work. They have a fast-cutting alumina
abrasive grit for quick metal removal. The disc and the backing pad are
all in one. The disc can easily be trimmed down to expose a new sharp
edge. Your grinding accuracy and control will improve. Each package
of discs come with a 1/4" mandrel.
Quick Change Tap Adapters are used to reduce the amount of time it takes to change between taps. Insert the drive end of the tap adapter into the power tapper or tee-handle. No more time-consuming repetitive adjustment of the drive collet. Just pop the tap in and out of the Quick Change Ta Adapter.
