CARBIDE LENGTH

Hole Diameter			Max. Shallow Hole Depth
.1875"	thru	.3125"	.500"
.3126"	thru	.7188"	.625"

FLUTE STYLES

Straight Flutes - Good in a wide variety of applications
Right Spiral Flutes - Tend to bridge interruptions such as keyways, slots or intersecting holes; Good chip clearing ability for ductile materials and blind holes
Left Spiral Flutes - Also tend to bridge interruptions; Good for cast irons, heat treated steels and other hard materials; Do not use in blind holes
Expansion Reamers - Economical for abrasive materials
