The HELIQUAD Line is Now Upgraded with .500” Inserts


HELIQUAD

Highlights
ISCAR expands HELIQUAD SDMT 12 geometries, grades and the insert’s radii range for additional applications which guarantee economical 90° shoulder milling.


HELIQUAD SDMT 12 single-sided inserts with 4 cutting edges feature:
  1. New improved cutting geometries.
  2. .063” corner radius.
  3. New HELISTAR chip former.
  4. New QDMT 1205…PDTN-M geometry with IC330 grade.


Additional CVD and PVD coated grades, which emphasize higher durability and flexibility with more tool life for productive milling.

The new and improved geometries feature
  • Robust and durable insert design
  • A wide wiper for excellent surface finish
  • Effective and economical solutions for milling true 90° shoulders


The inserts which are mounted on F90SD tools are produced with SUMO TEC carbide grades and provide excellent performance with longer tool life.

In addition, the inserts are suitable for XQUAD SDK-12-C/HP extended flute cutters with conventional or high-pressure coolant outlets.

HELIQUAD-12 UPGRADE

SDMT 1205PDR-HQ-MM features
  • Helical cutting edge for reducing cutting forces.
  • The new design is characterized by a reinforced* insert body and cutting edge land with ~.008” compared to the previous ~.005” HELIQUAD insert geometry SDMT 1205…HQ-M design.
  • The new SDMT 1205…PDR-HQ-MM will phase out the SDMT 1205…HQ-M with the exception of IC810/910/950/5500 grades.



SDMT 1205...PDR-RM-MM features
  • Straight cutting edge intended for tools with a shell mill adaptation and extended flute cutters.
  • The new design presents a reinforced* insert body and cutting edge land with ~.008” compared to the previous ~.005” HELIQUAD insert geometry SDMT 1205…RM-M design with superior tool life.
  • The new SDMT 1205…RM-MM will phase out SDMT 1205…RM-M with the exception of IC910 grade.
  • Available with an additional 1.6mm corner radius and IC808/830 grades.


* The blue marked area presents the added reinforced volume.
Applications
  • Rough to semi-finish machining operations
  • Reinforced land, intended mainly for milling ISO P materials - carbon and alloy steel, ferritic and martensitic stainless steel and ISO H materials - hardened materials.
  • Milling square shoulders, slots, inclined surfaces, and cavities.


The newly upgraded inserts are suitable for right-hand cutting and are available in the following configurations:


HELIQUAD-12 Inserts Upgrade
ISCAR will continue to supply the old inserts until the stock is depleted, and then orders will be switched automatically to their new insert alternative.

HELIQUAD-12 Inserts Phase Out
ISCAR is phasing out the following inserts due to very low consumption and will continue to provide the above inserts until stock is depleted.
Alternatives inserts are available in the system.

HELIQUAD-12 Expansion

SDMT 1205PDR-HQ-HS
The insert’s HELISTAR style chip former geometry splits the chips into small pieces and generates low cutting forces, which enables increased feed rates and depth of cut (DOC) for higher machining productivity.

SDMT 1205PDR-HQ-HS features
  • Significantly improves chip evacuation.
  • Reduces cutting load, enables high table feed and DOC.
  • Reduces vibrations.
  • Reduces heat generation.
  • Suitable for machining long overhangs, poor work-holding conditions, or low machine tool rigidity.


Applications
  • Rough to semi-finish machining for milling ISO P materials - carbon and alloy steel, ferritic and martensitic stainless steel.
  • Milling square shoulders, slots, inclined surfaces, and cavities with high tool overhangs.


Benefits
  • Increased productivity achieved by increasing the cutting parameters.
  • High performance when milling under low unstable conditions.
  • Low power consumption allows applying the cutters on machine tools with limited power, small capacity machining centers and turn-milling machines.
  • The shredded chips reduce the common built-up phenomenon.
  • Improved chip formation control - less chip entanglement and reduced risk of machine stops.


QDMT 1205…PDTN-M

  • Inserts with 4 neutral cutting edges for general use.
  • Available with a corner radii of .0315/.0630/.0787/.1260” and IC330 SUMO TEC carbide grade.
  • Mounted on F90SD…-12/SDK…-12-C/HP/FT/A and SDN/FDN/FST/SSB…-12 slotting cutters as well.


Applications
Rough to semi-finish machining for milling ISO P - carbon and alloy steel, ferritic and martensitic stainless-steel, ISO K - cast iron and ISO H - difficult-to-cut materials.


Cutting recommendations for the above new and upgraded inserts
  • The table below defines initial feed rates.
  • For initial cutting speeds refer to ISCAR’s recommendations for carbide grades.


Calculating cutting feed rate
ƒz=ƒz0×Kef×Ks
where
ƒz0 - Basic feed (Table 1),
Kef - Engagement factor ( Table 2),
Ks - Stability factor (Table 3)


Table 1 - Basic feed, ƒz0, mm/tooth
(1) in accordance with VDI3323 standard


Table 2 - Engagement factor Kef
ae - Width of cut
D - cutting diameter


Table 3 - Stability factor Ks


SIZE 12 Complete Line
