CONSIDERATIONS IN SELECTING THE PROPER PRECISION CUTTERS

CUTTING REQUIREMENTS:

Different cutting edges and length determine the required squeeze pressure, shock, and the amount of "pinch or spike" left on the wire.

PROMINENCE OF THE SPIKE OR CUT WIRE LINE IS A FUNCTION OF:
Jaw, bevel, and cutter edge type as new (angles of jaw (<j), of hone (<h), of bevel (<b), and amount of bevel) The edges' past use and current condition The joint's past use and current condition The material, hardness, and diameter of wire cut.

BEVEL cutting edges are used where "pinch or spike" left after cutting is not critical and where shock transmitted will not damage parts or components. Bevel edges optimize the number of cuts over the lifetime of the cutter, but require more pressure to make cuts.

SEMI-FLUSH edges reduce shock transmittal, lessen pinch, spike, and squeeze pressure.

FLUSH edges should be specified when requirements call for minimal spike and very minimum shock transmittal. They are more ergonomic and require even less squeeze pressure than full flush. Flush edges have .002 bevel.

HEAD AND TIP SHAPES
Diagonal Cutter) head shapes are oval wide, taper wide, oval slim and taper slim. The "slim" option brings a finer point and ease of access in tight places, but also increases the risk of tip breakage due to the smaller cross sections near the tips. The user has trade-off choices between long edge/tip life with a more blunt (wide) nose, and the finer edge-tip design (slim) with greater risk.

Confines of the work often dictate the finer points. Tools used within specified limits cut the risk to nearly zero. Back .125" from tips, taper slim cross sectional area is as little as only 50% that of the wide head. Users can extend tool life by using wide head tools if confined areas do not dictate otherwise.

CUTTER EDGE LINES
For electronic use, most work is done at the tips and cutters are honed for maximum life at the tips. While holding the cutter lightly closed you should see and increasing amount of light from the tips back toward the crotch. This optimizes life of tip cutting tools.

Perfect parallel hone is available if cutter is used full length on wire.

Tip hone. Light in the crotch is desirable for most electronic work.

LONG NOSE AND NEEDLE NOSE TIPS AND EDGES
Applications in electronic normally require small tips for intricate work. Tips vary on different types and styles. Beveled edges are standard on smooth jaws.

LEAD CATCHERS or wire trappers are available on some cutters, their purpose is to hold cut leads from flying or falling into critical work areas. Thin design offers good visibility and cutting access.
