REAMER SELECTION GUIDE
BASED ON HOLE CONDITION

CARBIDE LENGTH

Use flute long carbide for hole depths exceeding maximum shallow depth

Hole Diameter			Max. Shallow Hole Depth
.1875"	thru	.3125"	.500"
.3126"	thru	.7188"	.625"
.7189"	thru	1.0625"	.750"
1.0626"	thru	1.5000"	.875"

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
