Special Tool Configurations

Special Tool Configurations
Special Overall and/or Flute Lengths
While we recommend using a standard overall and flute
length whenever possible, there are situations where the
use of special overall and/or flute lengths are warranted.
If you have any questions on the relative merits of using
special lengths, CJT’s application specialists will be glad
to be of assistance.
Special Point Geometries
With many applications, special point geometries can
increase tool life and/or performance. Any type of point
that can be put on a high speed drill can be put on a solid
carbide drill and most on a carbide tipped drill with some
exceptions.
Some of the special point geometries we offer:
Ball nose and radial lip point grinds
Double angle points
Flat points (180 degrees)
Split points
“K” notch points
Zero and negative rake cutting edges
Polyrake point
Spur and Brad points

Double Margin Drills
Both solid carbide and carbide tipped drills can be made with
“double margin” construction for applications requiring
added stability and straightness while drilling.
Multiple Diameter Step Tools
Drills, reamers and end mills can all be produced as step tools.
Solid carbide and carbide tipped construction is available in
non-coolant fed and with internal coolant holes.
Special Coatings
TiAlCN and Wc/C are two examples of the special coatings
available. Our application specialist will help you determine
which coating is appropriate for your application.
Ask our Application Specialist
The above are some examples of special purpose drill
configurations we make. For more information on what we can
produce or what we would recommend in special situations
please contact CJT’s application specialists.

Carbide Tip, 135° Split Point, Screw Machine Length Drill
Premium carbide grade provides excellent wear resistance when cutting
cast aluminum, bronze, cast and ductile irons, titaniums, fiberglass, hard
plastics and non-ferrous metals. Not recommended for soft steels.
Style 115
•
135° four facet split point improves true position and is an
excellent starting drill for longer coolant fed drills.
•
2 to 2.5 times faster speed than standard high speed steel with
better hole finish.
•
•
Right hand spiral, right hand cut, heavy duty high speed steel body.
Allow 2.5 x Ø of flute for chip exit up to 1/4” (6.35mm),
2 x Ø up to 7/16” (11.1mm) and 1.5 x Ø over 7/16”.
