Optimized Parting and Grooving Line

2/9
The RHINOGROOVE is an optimized insert with an overall reduced length developed for efficiency in shallow depth of cut parting and grooving machining.
When compared to both the competition’s and existing products, the RHINOGROOVE’s center of gravity promotes better stability while the vibration during machining is minimized by the optimized holder pocket design that enables powerful clamping of the insert.
Since vibration is the single greatest influence on tool life in parting and grooving, the RHINOGROOVE guarantees improved stability and longer tool life due to minimized vibration during machining.
The RHINOGROOVE line comes in C and J type chip breakers which are available as standard items in either 2-3mm insert widths.
Features Ideal for small component and shallow depth of cut machining due to the insert’s reduced length relative to
the existing and competition’s equivalents Minimized vibration due to the insert’s center of gravity Optimized holder pocket design for better clamping Both ‘C’ & ‘J’ type chip breakers have excellent chip segmenting capability A range of grades (TT9080,TT7220,TT8020) to machine several types of materials
KEY POINTTaeguTec has released a brand new optimized line, the RHINOGROOVE, for parting and grooving machining.

C chip breaker For hard materials and tough
applications For general applications on steel,
alloy steel and stainless steel Medium-to-high feeds
J chip breaker For soft materials, parting of
tubes, small diameters and thin-walled parts Low cutting forces and smaller
burrs Excellent machining straightness Low-to-medium feeds
Recommended feed range as a function of insert widthMaterial: SAE4140 (HB240)
RHINOGROOVE is optimized for parting and grooving machining, TaeguTec recommends applying 40-50% of the suggested feed rate in external turning applications.
