Sandvik Coromant T-Max P Carbide Turning Insert, VNMG, 35 Degree Diamond, MM Chipbreaker, GC2015 Grade, Multi-Layer Coating, VNMG 332-MM, 3/8" iC, 0.0315" Corner Radius (Pack of 10)

Description

The Sandvik Coromant VNMG GC2015 carbide indexable insert with a choice of MM
or MF chipbreaker has a diamond shape (also called rhombic) with a 35-degree
cutting angle, providing a balance of shock and wear resistance for medium
machining and finishing on stainless steel in average to good conditions. This
double-sided negative insert has chip grooves on both sides, a hole in the
center, and four cutting edges. It has strong edges, zero clearance, and is a
better choice for external turning than a positive insert. The GC2015 grade is
a TiCN, aluminum oxide, and TiN coating applied with a medium-temperature
chemical vapor deposition (MTCVD) finish over carbide. It has a balance of
wear and shock resistance for average to good conditions during turning of
stainless steel. This insert coating is also for continuous cutting at
moderate to high cutting speeds. MTCVD coatings provide toughness and
smoothness without limiting wear resistance. The VNMG GC2015 is available with
a choice of two types of chipbreakers: MM or MF. The MM chipbreaker provides
better chip evacuation for medium machining than the MF chipbreaker, which is
for finishing operations. Tolerance of distance from outer edge of inscribed
circle to point of diamond is + or -0.002 to 0.005”. Tolerance of the
theoretical diameter of the insert is + or – 0.002 to 0.005”. Insert thickness
tolerance is + or – 0.005”. Different insert shapes and sizes may have
different inscribed circle (iC) measurements, which are related to the
insert’s range of cutting depths, speeds, lead angle, and feed rates. The
inscribed circle is the largest circle that can be drawn within the edges of
the insert shape. In general, as the insert size and iC become larger, the
maximum cutting depth increases. The cutting depth influences the metal
removal rate, number of cuts, chip evacuation, and power required when using
the insert. Indexable inserts are small cutting tools designed to remove
material in external and internal cutting applications such as turning,
milling, drilling, and grooving. They are held by an insert holder, have
multiple cutting edges, and can be rotated when one edge wears down. Multiple
inserts can be used to accomplish a variety of cuts in one operation. An
insert is either positive or negative, which refers to the rake or clearance
angle at which the insert removes material. Inserts are coded according to
their specific cutting and application capability (e.g. VNMG 16 04 04-QM).
Each part of the code represents details of the insert shape, nose angle,
clearance, tolerance, size, geometry, grade, and chipbreaker style. Sandvik
Coromant produces tools for turning, milling, and drilling. Headquartered in
Sweden and represented in 130 countries, the company manufactures tools used
throughout the metalworking field, including the automotive and aerospace, die
and mould, and general engineering industries. All Sandvik Coromant inserts
meet ISO and ANSI standards. Matching Inserts to Holders These inserts are
part of the Sandvik Coromant TMax P Negative Insert family, which means they
can be used with CoroTurn RC, a clamp-style insert holding system. This system
is for use when stability and security are essential for productive turning of
large components. The system is mostly used for external turning, from
roughing to finishing, but also for internal turning.

Features:

• Designed for turning operations from medium machining to finishing — on stainless steel in average to good conditions
• GC2015 grade is a titanium aluminum nitride (TiAlN), aluminum oxide, and titanium nitride (TiN) coating over carbide that has a balance of shock and wear resistance
• 35-degree diamond shape is suitable for longitudinal turning, profiling, and when there is limited machine power and tendency toward vibration
• MM and MF chipbreaker styles help prevent buildup of chips during medium machining or finishing operations at moderate to high cutting speeds
• Negative double-sided insert has zero degree clearance and a strong edge for external turning
