FRACTIONAL TYPE 3412 - TAPER SHANK - RIGHT SPIRAL FLUTES
TYPE 3412
Carbide tips brazed to one piece hardened alloy steel bodies. Right spiral polished flutes.
Designed and manufactured for maximum tool life. Right spiral flutes have a greater chip clearing ability for use with ductile materials, highly abrasive materials or blind holes. Finishes are much better as spiral flutes tend to bridge interruptions such as keyways, slots or intersecting holes.
