<h2>KaVo INTRA Head L80 FG Repair Guide: The Contra-Angle Head That Takes Turbine Burs</h2>

&nbsp;

Most contra-angle heads take latch-type contra-angle burs. The KaVo INTRA head L80 is different: it holds FG turbine burs with a 1.6 mm shank, running at 1:1 on your contra-angle shank.

That unusual combination is what makes it useful, and what makes its chuck worth protecting.

&nbsp;

At a glance: 1:1 &middot; FG turbine burs, 1.6 mm &middot; push-button chuck &middot; max. 40,000 rpm &middot; Mat. no. 1.004.4456.

<h2 style="text-align:justify">Understand What the L80 Is Designed to Do</h2>

&nbsp;

According to KaVo&#39;s INTRA heads page, the L80 is for finishing and forming chewing surfaces after the filling material has hardened, for large and effective pre-polishing, and for caries excavation with FG hard metal drills.

&nbsp;

Did you know? On KaVo&#39;s US site, the L80 is listed as the &quot;INTRA friction grip head L80,&quot; which reflects its FG bur design.

&nbsp;

<h2 style="text-align:justify">Recognize the Signs of Wear</h2>

&nbsp;

<ul>
	<li>
	Warning sign: An FG bur that slips or will not release
	</li>
	<li>
	Warning sign: Vibration during occlusal finishing
	</li>
	<li>
	Warning sign: Roughness or heat that follows the head onto another shank
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">Decide Whether to Repair or Replace</h2>

&nbsp;

KaVo says INTRA heads should be replaced after several years of use, while the contra-angle can keep working. An evaluation helps you weigh repair against a new L80.

&nbsp;

<h2 style="text-align:justify">Check Warranty Before You Ship</h2>

&nbsp;

KaVo lists a 2-year warranty for INTRA heads. A newer L80 may be covered through KaVo REPAIR.

<ol>
	<li>
	Confirm it is an L80 by its material number.
	</li>
	<li>
	Test FG bur retention and release with a correct 1.6 mm bur.

	<li>
	Run it on a known-good shank to check smoothness and heat.
	</li>
	<li>
	Explain repair or replacement options clearly.
	</li>
</ol>
