 |
 |
| CS Chip Breaker - Cut-Off Inserts | SPT Chip Breaker - Cut-Off Inserts | SC Chip Breaker - Cut-Off Inserts |
| The CUT3000 type-GS chip breaker is an evolution of Swiss-type cut off tooling. By using a new carbide forming technology, these inserts require less grinding to be produced while offering a decrease in overall cost of use. ‘Type GS EN’ grade offers supreme performance in carbon steels while the Type GS FN grade offers excellent performance in Stainless and Titanium applications. | The multidec® CUT3002 cut off inserts with type-SPT chip breaker feature a positive rake intended for use in soft and stringy materials. The SPT chip breaker comes in three different angles; SPT:20" rake for plastics such as Delrin, SPT06": 6"rake for stainless, SPT12: 12" rake for aluminum. | Cut-off inserts armed with the type-SC chip breaker are ideal for hard materials. This chip breaker is quite universal, used in roughing, finishing, and micro finishing. |
 |
 |
| SP Chip Breaker - Front & Back Turning Inserts | CP Chip Breaker - Front & Back Turning, Grooving Inserts |
| Front and back turning inserts with the type-SP chip breaker are ideal for finishing and micro finishing on materials such as aluminum, breaking up chips and preventing stringy chips from forming. | When creating deep features during front turning, back turning, or grooving, the type-CP chip breaker is vital for chip removal. The sharp articulated geometry will peel chips away and keep features clear of material during finishing and micro finishing operations. |
MULTIDEC® - CUT G-LINE INSERTS
With a focus on high productivity, process reliability, and the longest possible tool life, perfect chip control becomes a central issue in all modern production. These requirements are often difficult to fulfill with traditional ground chip breakers because of insufficient chip break and removal.
In comparison to traditional grinding technologies, new manufacturing technologies have increased the degree of design freedom tremendously, providing the ability to generate any three-dimensional shape. The new G-Line from multidec has adopted the use of this new free-form design technology, resulting in well thought-out chip breaking geometries that are fitted to the well-tried multidec -CUT 1600 and CUT 3000 series of turning inserts, providing maximum performance.
Freeform-modeled chip breakers achieve significant improvements in a wide range of materials when compared to ground chip breakers. This advantage is particularly evident with difficult to machine materials such as super-alloys. In addition to significantly improved chip control, multidec G-Line inserts can achieve up to 30% higher cutting values and up to 50% longer tool life.

 |
| GS12 Cut-Off Inserts | GT20 Cut-Off Inserts | GA20 Front Turning, Facing, Back Turning |
| A neutral chip control geometry offering wear-resistant sharp cutting edges enabling better chip control. Ideal for high cutting speeds. | Compared to the GS12 chip breaker geometry, the GT20 chip breaker has a sharp and slightly rounded cutting edge. It provides excellent chip flow, creating short chips and resulting in a smooth finish. These results can be experienced at higher feed rates | Based on the multidec TOP insert technology, this optimized version enables turning in three directions. Perfect chip control is maintained during facing, turning, grooving, and back turning. Inherited from the TOP insert technology, the GA20 enables up to 100% higher feed rate. |

MULTIDEC CUT3000 SERIES GLOSSARY TERMS
Chip Breaker: uses the drives of the machine to create an oscillation that produces small chips which are easier to remove, thus reducing machine downtime and ensuring continuous production.
Combi Holder: Combi holders allow the insert fixing screws to be mounted from the opposite side of the holder using tapped bushings, making it easier to change the inserts.
Coolant-thru Holder: holders with integrated coolant supply. Due to the high precision of the impact and the large pressure, the chip can be quickly and safely guided away from the cutting edge and the workpiece. This means a markedly longer tool life, coupled with high process reliability in series production.
G-Line Inserts: Freeform-modeled chip breakers achieve significant improvements in a wide range of materials in comparison to ground ones.
Gold Line Holder: The multidec Cut, Gold Line Holders provide a newly designed cooling system making it possible to double the lifetime of the cutting edges as well as increase the cutting parameters without having to accept higher wear.
IC: acronym attached to Utilis multidec holders with integrated (internal) cooling.
Indexable inserts: all indexable inserts are easily replaceable and are characterized by a very high repeatability. For the machining of all common materials, inserts are available in ideally matched carbide grades of coated and uncoated ultra-fine grain substrates.
Offset Shank & Insert Holder: the multidec shifted holders enable the cutting of short parts by enabling the cutting edge to move closer to the guide bushing therefore reducing the chance for deflection.
Offset Shank Holder: the multidec offset holders include clearance for extended nose guide bushings or for subspindle/pickoff clearance therefore providing an ideal cuttoff situation in tough applications.
Standard Holder: the basic multidec square shank tool holder for the CUT 3000 Series without internal coolant capability.
Short Holder: shorter holders that enable the use of multidec inserts on commonly available quick change tooling systems. All multidec Short holders feature internal cooling.
Utilis multidec®-CUT: the multidec range of indexable insert tools offer cutting-inserts and holders for internal and external turning, on swiss-type automatic lathes.
3000 STANDARD HOLDERS
Multidec standard holders are your basic square shank tool holder, a true Swiss-style holder where the cutting edge is flush with the mounting surface of the shank with no offset. These holders get your cutting insert right up on the guide bushing for maximum rigidity. Universal amongst all multidec holders, the insert pocket provides both clearance and protection for all CUT 3000 series geometries and chip breakers.
The recessed pockets of the multidec holder system is a great feature that prevents the loss of the mulditdec holder when wear or breakage occurs. For example, if you lose a cutting edge on the CUT 3000 insert or if part of the insert breaks off, you are able to index the insert around and utilize the other edge.
This type of pocket is the same across the whole CUT 3000 system and is compatible with all CUT 3000 series inserts, which includes geometries for cutoff, front-turning, back-turning, grooving, threading, and even full-radius grooving. Full-radius grooving is available "off the shelf" and is a special execution that is not readily offered by other tooling providers.

Accurate coolant delivery to the cutting edge is essential when machining modern materials for precision, but not all holders feature internal-cooling capability, which is the preferred method for delivering cutting lubrication. Standard holders offer high rigidity and repeatability, but they rely on external coolant hoses to deliver lubrication. Applying coolant as close to the cut as possible is important, and it can be difficult to limit space between the material and cutting insert without internal coolant capability. Don't worry, GenSwiss offers a multidec line of coolant-thru tooling wedges with an assortment of various quick change connectors, fittings, manifolds, and high-pressure coolant hoses sold in kits or separately à la carte.
