ROPER WHITNEY 8 130020080 Hole Punch, 2-1/8 Inch Throat Depth, 1/2 Inch Hole

Roper Whitney 8 hole punch is a medium-duty and portable hand punch producing 5 tons of force, equivalent to the capacity of a 1/4-inch diameter hole through a 1/4-inch metal plate.

Working Mechanism:

• To prevent the metal from being crumpled and guarantee a clean cut, the pointy edges puncture first.
• A clean hole is punched in the object when the puncher is pressed down.
• The initial hole-making incisions are made by the puncher's sharp edges, and the procedure is finished with a last downward stroke.

Features:

• Roper Whitney 8 hole punch uses 90-degree arc movement with the upper handle of the unit to punch and strip metal. The upper handle stays fixed in position at both ends of the arc.
• It includes a 9/32-inch round punch and die set.
• The upper handle can be reversed for front pulling operation when used with a punch bench base.
• It delivers a hole punch throat depth of 2-1/8 inches.
• This unit provides a 1/2-inch hole punch size.

Compatible Accessories:

Frequently Asked Questions:

Q. What is the difference between a dovetail punch and a hollow punch?

A. Dovetail punches are ideal for fabricating interlocked dovetail joints when the outside diameter of the gasket is larger than the width of the material to be cut. These units feature a padded rubber grip to offer maximum comfort during continuous operation. Hollow punches, on the other hand, are ideal for creating single-diameter holes (bolt holes) and dual-diameter rings (washers) in a single operation. They allow quick & precise hole-punching on flange gaskets.

Q. How do you measure a hole punch?

A. Mark both sides of the second hole's centre by dividing the hole punch's diameter by two. For instance, each end of the second hole is 1/2 inch from the centre for a hole punch having a one-inch diameter.

Q. How deep do hole punches go?

A. 0.5 inches.
