KATO Tangless Removal Tool

Remove Threaded Inserts With Ease.

KATO Tangless Removal Tool (2KRT) is unique in the helical coil screw thread insert industry. The KATO Tangless removal tool simply threads into the installed insert, grabs the removal notch and threads the insert out without damaging the internal STI threads or surface of the casting.

As an added benefit, the mandrel assembly portion of the KATO Tangless removal tool can be withdrawn from the blue and red handle and inserted (using the KATO Hex Kit 2KHEX-1K) into the KATO KFS-20 (CT5420) or KFS-25 (CT5425) brushless electric drivers for high-speed removal or adjustement, for a large number of inserts. This is impossible with conventional tanged style inserts. See the KATO Tangless Removal Tool in action by visiting our Video Workshop in KATOpedia.

For Tangless inserts ONLY

Features & Benefits - For Tangless 2KRT only

Quick, non-destructive removal of Tangless inserts.
Prevents damage to the parent material and expensive castings.
Ability to back out or adjust an insert that has been installed too deep.
Compatible with screw thread inserts from Helicoil, Recoil and others.
Can be used in KATO electric drivers for fast and convenient removal of a large number of inserts.

KATO Tanged Extraction Tool

For Tanged inserts Only.

The KATO Tanged Extraction Tool (KRTV) is designed with a wedge-shaped tip and an integrated handle. The sharp tip is used to dig into the installed tanged insert (a hammer may be required). The handle is then used to turn the tool counter-clockwise while applying pressure until the insert is extracted from the parent material. Using the KRTV tool the following can occur:

Slow extraction process.
Damage to the surface/finish of the parent material.
Damage to the inserts.
Possibly damage the STI threads.
Extraction may not be possible if inserts are installed too deep.

For Tanged inserts ONLY

To avoid damage to your casting, and minimize rework, consider switching to KATO Tangless CoilThread inserts and never use a destructive tanged extraction tool again!
