TRISTAR® Round Punch/Die Sets
ITC supplies TriStar® Punch/Die sets (Manufactured in Germany by ALFRA), which
can punch holes in mild steel plate, max. thickness 3.0 mm., without using a
hydraulic punch – just a draw stud with ball-bearing head.
While a hydraulic cylinder with appropriate pump may also be
used if available, TriStar® dies and punches can operate
mechanically up to large diametres thanks to the special
design of the 3 cutting edges and the ball-bearing draw studs.
Punches and punch sets are available for a variety of sizes,
including metric, Pg as well as NPT knockouts.
TriStar set include punch/die sets as indicated, ball-bearing draw studs, one pre-dill HSS bit
and one can of grease, in a plastic case.

Rectangular Punch Sets
These unique punch and die sets are specially designed
for punching rectangular holes of the exact sizes required
to install multi-pole connector housings.
Not only do they punch the rectangular knockouts, but also
indent 4 guide points for drilling the appropriate mounting
holes.
They are designed to operate by a hydraulic cylinder (Part No.
502.088), or hand hydraulic pump (Part No. 502.097), are easy to
align, and offer considerable time and cost savings compared to
drilling/cutting, for installation of popular multi-pole connectors
(ITC’s ILME product line) and cable passing devices such as ITC’s
ICOTEK® models.
Maximum steel thickness: 2.0mm. Supplied in a plastic case with draw stud.

4 centering mandrels are placed in the correct position at the die. When
die and punch are pressed against each other, the drilling position gets
marked on the interjacent work sheet.
These 4 marks can be used as a drilling template. With help of a twist
drill, the drilling assembly for connectors can be done easily.
Square Punch Sets
Each set must be used with a hydraulic cylinder (driver) such as Part No. 502.088 or hand hydraulic pump Part No. 502.097, and

Hydraulic Pumps and Punchers
ITC offers manual/battery powered hydraulic pumps as well pneumatichydraulic pumps, and hydraulic cylinders.
HH-700/HYP-700 models automatically release when the maximum pressure of
700bar (10,000psi) is reached. They come equipped with a 2m hose with connector
and a steel carrying case.
The pneumatic-hydraulic power pack (Part No. 510.702) is a monoblock unit
equipped with a pneumatic actuator which in turn operates a hydraulic pump. It
has an oil tank of 2.1 liters, and operates at an air pressure of 3 to 8 bar. It is
supplied complete with oil hose and sound absorber.
502.097
510.702
Part No. 502.097 is a hand-held hydraulic pump in the same body as a cylinder head:
no hose! Ideal for the shop floor, it can be coupled to punch/die sets up to 64 mm
dia. (3.0mm mild steel) or up to 85mm dia. (2.0mm mild steel).
Maximum operating pressure is 650 bar, and because of its all-aluminium construction
it weighs only 1,600g and is supplied in a plastic carrying case with 2 draw studs, one
pre-drill HSS bit 11mm and 3 adapters.
This pump is also available in kits with punches.
Part No. 502.701 (AKKU) is a hand-held, battery powered hydraulic pump/punch: practical
handling with high performance rechargeable battery of 18V for round, square and
rectangular punches for builders of control cabinets, panels and electrical system.
The high performance rechargeable batteries can be inserted in two ways so you can obtain
a weight counterbalance.
This kit includes the punch, battery, charger, 2 draw studs, one pre-drill HSS bit 11mm and
one distance bush.
Battery: 18Vm 3.0Ah NiMH
Battery Charge: 45 min. after complete discharge
Charge Cycles: ~500 under normal circumstances

Hole Saws and Multi Step Drills
TCT Hole Saws
A new family of carbide-tipped hole-saws designed for work on mild steel,
stainless steel, aluminum, plastic or wood.
The new TCT Hole Saws presented by ITC and manufactured in Germany by ALFRA vastly
differ from conventional HSS bi-metal hole saws currently found on the market. They provide
high precision cutting, combined with a long tool life, which can be extended further with replaceable center drill bits or arbors,
and the possibility of tooth sharpening, if required.






For use with hand drills (recommended to max. hole dia. 40 mm = 1 9/16”)
or with vertical drills/drill presses.
Models available from Ø 16mm = 5/8” to 150mm = 5 7/8” approx.
CAD-designed cutting carbide tips optimize cutting capacity and reduce need for re-grinding.
Replaceable centre bit with tapered tip – no need for center punch.
Removal of core after cut is made simple thanks to the replaceable ejector spring.
Arbors can be replaced on models from Ø 32mm to Ø 150mm (smaller models are made from a single piece arbor/saw and
cannot be replaced). The centre bit can be replaced on all models.
