Durabore® Centerfree Cutters
DuraBore®
center-free cutters are designed to increase through hole drilling productivity
while improving hole accuracy. Rugged enough for structural steel fabrication,
DuraBore® cutters adapt quickly and easily to most magnetic base drills,
drill presses, milling machines and CNC machining applications. DuraBorem
cutters out perform twist drills and older style annular cutters eliminating
pre-drilling, step drilling and hole finishing operations. Solid pilot
locates cutter position, guides coolant to cutting edge and retracts into
cutter during drilling cycle. Proven alternating tooth geometry minimize
kerf area and evenly distributes chip load to multiple cutting edges reducing
horse power and drilling feed pressure. Scrap material advances away from
cutting edges, forming an easy to remove nest of chips above material
surface. DuraBore® cutters are ideal for most drilling applications
including elongating holes and trepanning operations. DuraBore® cutters
are manufactured from premium high-speed steel and specially heat treated
for cutting edge toughness increasing tool life between sharpening.
