To meet the growing demand from the energy/powergen sector, ISCAR has launched a line of extra-strength standard grooving tools for more efficient and secure machining of T and L slots so common in turbomachinery. Previously such tools were available only as specials and in much more lightweight designs, the company reports. Key applications include T grooves on turbine disks, rotors and casings made of superalloys.
Huskier than any comparable standard or special available today, the LPGIR insert provides a very rigid platform with a choice of chipformers suited for either OD or ID work in long- or short-chipping materials. The cutting tip is very thick and longer for stronger gripping. This heavy-duty design brings a level of rigidity that improves finishes and enhances process security in high added-value components. By minimizing the risk of catastrophic tool fracture and reliably prolonging "time in the cut," new ISCAR LPGIR inserts even permit unattended operation.
For reliable chip evacuation in grooving and to meet widespread market preferences, advanced ground chipformers generate desirable long segments and, to minimize re-cutting, direct them out of the tightest groove. The PR type chipformer handles both right- and left-hand cuts; the asymmetric T type chipformer cuts only to the left. Also available as a standard is the P-type chipformer for limited, less challenging operations including short-chipping metals. Additional chipformers are available on request.
ISCAR LPGIR/L inserts are available in a width range of 2-5mm (.079"-.197") and can handle grooving depths up to 6.5mm (.256"). Matching HLPGR/L tools cover the size range to ensure system rigidity in all cases.
Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.
The milling heads have been designed for shoulder roughing, semi-finishing and finishing applications with ramping down capability. The milling heads are available in .312-1.00” diameter range.
A new family of tools and economical 5 pocket adapters for existing TANG-GRIP inserts in sizes of 2 and 3mm. These new adapters will allow parting applications of bar diameters up to Ø45mm. A new SLIM-GRIP 1.2-1.6mm inserts for a pentagonal adapter suitable for parting up to 22mm bar diameter.
The advanced design combines a strong insert structure, a durable cutter body, secure mounting, and advanced carbide grades. This innovative solution enables face and square shoulder milling, while providing an additional option for milling close to shoulders where there are workpiece or work…
The NEOTURN XNMG demonstrates excellent chip control and highly stable tool life in a wide range of applications. The NEOTURN system also enables machining complicated workpiece shapes close to the tail stock where space is limited. This can be performed without replacing the holder and decreases…
When mounted in a NEOFEED tool, the insert enables a positive tool rake angle which assures smooth cutting and reduced cutting forces and power consumption. The insert pocket has a dovetail shape that provides rigid and reliable insert clamping and improves the a cutter’s capability to withstand…

The spline connection designation is SP… where the no. indicates the connection size.
The general duty cutting geometry of the heads is suited for efficient slot milling on a wide spectrum of workpiece materials for maximum depth of cut.
ISCAR is introducing 17 mm diameter PENTA inserts, designed for machining small size parts with up to 4 mm maximum grooving depth capability. The inserts are available in a range of widths from 0.25 to 3.18 mm, with different edge configurations for parting, grooving, turning and threading.
The XNMU inserts are the original concept of double-sided inserts with 4 right-hand and 4 left-hand helical cutting edges for slot milling cutters. These inserts are made of SUMOTEC carbide grades, designed for milling alloy steel, ferritic and martensitic stainless steel, and cast-iron.
The drill bodies are available in 3xD and 5xD length to diameter ratios. The inserts are supplied in a specifically developed user-friendly key, enabling easy mounting with no setup time.
