Deep hole drilling is very popular in the automotive, die and mold and aerospace industries. ISCAR took the gundrill technology one step further when developing the new CHAMGUN for deep hole drilling; this is a gundrill that enables the replacement of drilling heads while the driver is still connected to the machine. The "No Setup Time" concept enables quick head changes without the need to remove the drill from the spindle while indexing. The CHAMGUN is the ultimate economical solution for deep drilling. A polyamide plastic key is used for clamping and removing the CHAMGUN head.
A single CHAMGUN body can carry many different types of drill head profiles, designed for use on various materials. Each drill body can carry standard drilling heads within a range of 0.2 to 0.3mm. the CHAMGUN drill range is 9.8 to 16.19mm. drilling heads are available in half and whole sizes as standard items. Each drill pocket can carry a variety of drilling head diameters and head geometries.
The drill features an innovative unique pocket which can sustain at least 15 head replacements. The connection between the pocket and tube is by a new welding process for high torque resistance. Each drill pocket can carry a variety of drilling head diameters and head geometries and chipbreakers designed for use on various materials. ISCAR's GDI inserts can be reground a minimum of 10 times. However, head length should not be shortened to less than L-D. The end result is excellent straightness and concentricity inside the hole with high hole precision center alignment. In addition, surface roughness is easily obtained within the range of 0.4-1.6 Ra.
Additional features:
Carbide grades — coated and uncoated
Profiles — standard pad profiles
Drilling precision of IT7 to IT9 tolerance can be achieved
Re-boring is often unnecessary It is possible to regrind and recoat the drilling head up to 10 times, still obtaining good repeatability.
Self-guided drill for producing deep holes with good accuracy and fine surface finish. Has coolant passages that deliver coolant to the tool/workpiece interface at high pressure.
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.
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…
