SAFETY & USE
Punches are designed to punch holes in metal and other materials, mark metals, drive or remove pins and rivets, and align holes in different sections of metal. Punches are designed for use on metals softer than the punch itself and should never be used on stone or concrete.

Strike the face of the punch squarely with a ball pein or machinists hammer. Never strike with a nail hammer. Always strike the punch with a light, cautious blow when starting a job to determine the relative hardness of the material being punched. Always wear safety goggles when using a punch.

SELECTION
Punches are classified by the shape of the taper and point. Center and Prick Punches have a sharp point for precise markings. Enderes® Center Punches are available in 7 different sizes and lengths. Enderes® Prick Punches are available in 3 sizes ranging in stock sizes from 1/4" to 1/2". Solid Punches are used before using a Pin Punch to start a pin. Enderes® Solid Punches are available in 11 sizes from 1/16" to 1/2". Pin Punches have a flat point and consistent taper and are used to remove pins and rivets. Enderes® Pin Punches are available in 16 different sizes with points ranging from 1/16" to 5/8". Alignment Punches have a long taper and flat point and are used to align holes in different sections of metal. Enderes® Alignment Punches come in 8 different sizes with points ranging from 1/8" to 3/8".

MAINTENANCE
A dull cutting edge may be sharpened using a common file as described in our "Maintenance" section below:

1. Always wear safety goggles when sharpening a cutting edge and when ever using a striking tool.
2. Rigidly support the tool being sharpened. Secure in a bench vise if possible.
3. Never use grinding to sharpen. This causes excessive heat and may result in a loss of strength, durability and temper.
4. Instead, use a file or stone of medium or fine grit and file away from the cutting edge. This directs heat away from the edge.
5. The original contour of the cutting edge or point should be restored. Prick Punches should be restored to 30 degrees and Center Punches should be restored to 60 degrees.Pin, Rivet, and Alignment Punches - flat and square with axis of tool.

Discard any punch if it is bent or show dents, cracks, chips, mushrooming, or excessive wear.
