Stops
Peaks Global keys have two stops, a bow stop and a tip stop. The bow stop gauges keys in all current prod-
ucts. The tip stop gauges only in non-domed face small format interchangeable cores made prior to March,
1996. Either stop may be used when code cutting depending on the machine employed.
Most Peaks key sections are paracentric and not designed to be clipped on a key bitting punch. Paracentric
keyways are preferred for their enhanced pick resistance. They also produce many more keyway variations
than flat bladed keys.
Factory bittings are tip to bow
Factory bitting lists are written tip to bow. When using card-type key machines such as the Ilco Universal II
or HPC 1200 CM, it is suggested that keys be cut bow to tip to lessen the effects of the backlash of the rack-
and-pinion mechanism. Care must be taken in reversing bittings written as tip to bow.
Tolerances and milling cutters
Peaks tolerances are tighter than most other brands. Both depth and spacing must be held /- 0.002"
for proper operation. Key machines must be kept in precise adjustment. The required cutter angle is 90
degrees for proper key insertion. A cut root flat of .046" is required. The 90MC or equivalent cutter is
recommended.
Position next to the Peak
In the position next to the Peak, cuts deeper than a #6 in the A2 system or a #3 in the A4 system require the
use of an asymmetrical cutter, such as the #1011.
The 90MC cutter can not be used as it removes the upper Peak when making these deep cuts next to the
Peak.
