This is the bit you want to use to install any of my weldless kits.
small bit goes from 1/8" to 7/8" in 1/16" increments. It has a 1/2"
stop which is ideal for the smaller weldless weldless sight kits (LP,
LK, TP, TK) and a 13/16 or 7/8" stop for putting in a 1/2" NPT weldless
- The large bit goes from 3/16" to 1-3/8" in 1/8"
(mostly) increments. It has a 13/16" stop for weldless bulkheads and my
larger weldless sight kit (LTSK, LTSK), a 1-1/8" stop for 1/2"
couplings (welded in) and finally a 1-3/8" stop for putting weldless
electric heating elements in. Important - this bit should not be used to
start holes. Drill a pilot hole first.
- For the best value
and max hole size versatility, you can get both bit sizes at a combined
discount. This gives you flexibity from 1/8" all the way to 1-3/8" in
Please note, these bits are not
the highest quality units you can buy (such as Greenlee, Klein, or
Irwin). However, those high end units also sell for over $40 each. The
bits I offer are a great value for someone looking to make less than 10
holes or so. If you keep them cool (let the work and bit cool down after
every two steps or keep dipping in oil or water for cooling) and run
them slowly, you'll get those 10 holes drilled before the bit is toast.
If you want a longer lasting bit, go for the $50 bits. IMPORTANT!! If
you spin the bit over and over without seeing a ribbon of metal being
cut, you're work hardening the metal you're trying to drill and also
dulling the bit. See more info on drilling in the instructions area.
is highly recommended that you start ANY size hole with a smaller pilot
bit approximately 1/8". Step bits are not very good at starting a hole
in virgin metal.
