Is there any utility (MS Windows/ Linux based ) to flash the Kinetis boards directly? I have an already prepared binary to download into my TWRK70F120M board and don't want to install and create projects CodeWarrior.

You could use for example the Segger J-Link with the J-Link software to flash any ARM devices.
Other vendors like P&E have similar tools and utilities.
Or you could use gdb directly with a debug probe to flash your binary to the board: Command Line Programming and Debugging with GDB | MCU on Eclipse

All these options do require a JTAG probe.
Is there some standalone software tool which can use the on board USB (OSJTAG) connection on K70 to connect and then flash the binary image?
Then you probably should have a look at the USBDM project (see Debug External Processors with USBDM and Freedom Board | MCU on Eclipse and USBDM: USBDM Debugger interface for Freescale RS08,HCS08,HCS12,Coldfire and ARM-Kinetis Devices. ). It comes with standalone flash programming tools.
