For the high productivity of waking holes,
Tungaloy has now upgraded its exciting TDX drill series of
indexable insert drills. This market leading range of
drills for machining holes from 12 to 54 mm diameter now has the
new AH725 insert grade added to the series to deliver the
highest speed production levels with maximum performance
when machining steels and stainless steels.
Available with drills in 2XD, 3XD, 4XD and 5XD,
the Tungdrill Twisted utilises Tungaloy’s new TDX concept
that allows stable and efficient machining by using four corners
of the proven parallelogram shaped inserts.
The drill body also incorporates the TDX concept that works in
conjunction with the insert geometries to further enhance
stable cutting. As a result, exceptional balance can be obtained
and chatter can be constrained to deliver exceptional
surface finishes inside the hole.
To improve swarf evacuation the Tungdrill Twisted has two twisted coolant
holes in the drill body to increase the fluid flow by 50%,
this further improves surface finish and chip removal.
The combination of innovative new insert and drill designs combined
with the twisted coolant holes, promote swarf evacuation,
improves surface finishes, tool life and productivity.
The drill body also guarantees a long tool life credit to its specialised
drill body coating that is hardened to improve rigidity.
The new AH725 insert for the Tungdrill Twisted is a PVD coated grade
that incorporates Tungaloy’s ‘special surface technology(PremiumTec)’
that dramatically improves resistance to chip welding and insert edge chipping.
The newly improved coating layer features great adhesion strength between the coating and substrate.
This works in conjunction with a well balanced micro alloy substrate
that is effective for plastic deformation resistance and improves toughness.
The AH725 insert improves wear resistance when high speed machining stainless steel,
it also delivers excellent chip control and prevents burrs with the combination of a twisted drill design,
high powered coolant flow and innovative insert geometries. For the Tungdrill Twisted with AH725 grade,
Tungaloy has developed three insert types, the DJ, DS and DW types.
The DJ type is a general purpose chipbreaker usable for almost all applications.
It features low cutting forces and allows stable drilling with its deeply
formed chip groove that performs exceptionally free cutting action and effective chipbreaking.
The DS type has an entirely new rake face design,
strengthened corner and sharp cutting edges that enable it to perform excellent chip control
for gummy materials such as stainless steels and low carbon steels.
The DW type incorporates a new wiper design,
extremely strong insert corner and chipbreaker for high feed machining.
In comparison with conventional inserts,
this chipbreaker allows higher feeds and produces superior surface finish.
The three chipbreakers for the new AH725 grade make the new insert suited
to the machining of low carbon steel, stainless steel, carbon steels, cast irons and aluminium alloys.
