MRA X-creen bolt-on spoiler blade installation

Posted on August 29, 2013 by TwistedThrottle.com There have been 0 comments

We have been alerted by the fine people at MRA that using a brand new drill bit made for drilling metal could crack the screen when drilling to perform a bolt-on installation of a MRA X-creen spoiler blade.

It’s important to have the correct drill bits so you don’t chip or crack the material. Irregular holes and rough edges could lead to cracking, even months after the drilling occurs.  

The most effective drill bits for plastics are spur-point bits, also known as dowel bits. They are specifically angled to make smooth cuts in the material. 

Note: it is possible to use a metal drill bit, but the cutting edge at the face of the drill bit has to be ground down so that the cutting edge is not as sharp as a new drill bit. 

Below are some simple instructions that will prevent cracking:

  1. Use a piece of plastic or wood behind the screen for support, pressed against the opposite side exactly at the hole position. Use tape between this piece and the screen to prevent scratching.
  2. DO NOT bend the screen during the drilling process. 
  3. Drill the holes using very little pressure! Especially when the drill tool comes through the material.
  4. Reduce the drill speed as the drill bit exits the material.    

Using the correct type of drill bit and following these tips, you should have no trouble getting cleanly-drilled holes for mounting your new MRA X-creen.
