Product Announcement from SCT - Scientific Cutting Tools, Inc.


SCT  single point tools are designed for internal machining on a lathe. The helical boring bars can be used for both lathe and mill applications. All cutting tools are made from premium sub-micron carbide and are stocked with or without a TiALN coating.

Single Point Holders:

Coolant Holders have two flats on the shank, two coolant holes, and four set screws. They
can be used with or without the Back Stop. Standard holders have two set screws and no flats
on the shank. Page 15


Radial Relief Boring Bars:

Radial Relief Boring Bars have a radial relief behind the cutting edge that provides for a
strong cutting edge. Page 16

Mini-Boring Bars:

Mini-Boring Bars come in a range of diameters from 0.015 to 0.045 of an inch. They are
fluted to retain maximum strength. Page 16

Boring Bars:

Boring Bars come in both right hand and left hand cut. The right hand cut boring bars
come with or without a corner radius. The radius provides improved surface finish and
performance. These boring bars feature a primary and secondary relief behind the cutting
edge. Right hand with radius – Page 18. Right hand cut without radius – Page 17, Left hand
– Page 19

Diamond Tipped Boring Bars:

PCD Tipped Boring Bars are for cutting abrasive non-ferrous materials. CBN Tipped Boring
Bars are for cutting hard cast iron and ferrous metal over 45 RC. Page 20

Helical Boring Bars:

Helical Boring Bars have a helical flute that produces less side cutting pressure (Page 21).
This facilitates cutting unfavorable length-to-diameter ratios. The tools on page 22 are
dimensioned to cut the minimum bore when rotated on a mill.

Profile Boring Bars:

Profile Boring Bars are ideal for internal profiling on CNC lathes. Page 23

Back Chamfer Boring Bars:

Back Chamfer Boring Bars are designed to bore a diameter and cut a chamfer at the end of
a hole. They also excel for cutting thread reliefs. Page 23


Acme Threading Tools:

Acme Threading Tools come in both stub acme and full acme profiles. Page 24

Thread Tools Qualified:

Thread Tools Qualified have a positive top rake on the flute and a qualified length from the
thread form to the back of the tool. Page 25

Thread Tools:

Threading Tools come in many different sizes. This facilitates selecting the tool with
maximum rigidity. Page 26


Groove Tools – Retaining Ring:

Retaining Ring Groove Tools cut an internal groove with straight edges. Page 27

Groove Tools – Full Radius:

Full Radius Groove Tools cut an internal groove with straight edges and a full radius. Page 28

O-Ring Groove Tools:

O-Ring Groove Tools are ideal for machining a groove with tapered sides. Page 28
