Hi. We have a 1966 Holiday Rambler. We are trying to remove and replace all of the clutches screw from the aluminum trim around our camper. Trying to drill out the ones that won’t come out. We have used titanium drill bits and a special cone shaped screw bit that we were told is for this specific purpose. We were told to use the reverse setting. Nothing works! We have a makita drill and makita driver drill. There must be away to remove these stubborn screws. Currently we are trying to remove the screws that go into the floor from the outside. They also connect the belly pan. Thanks in advance.

The cone shaped bits I'm familiar with are called uni-bits. You can't run them in reverse as the cutting edge is on the side of the bit which would be cutting only when turning clockwise. Search for LEFT handed drill bits. They are designed to be ran counter-clockwise. If you get one the correct size as you drill a hole in the head it will usually grab the screw and start to roll it backwards.

Might try a dab of engine valve lapping compound in the screw head and on the clutch bit. If the screws heads are not countersunk, a thin cut off wheel mounted to a small right angle die grinder will cut some screw driver slots into them. If that dont work, might have to grind off the heads and take apart the unit in that fashion.

Put your clutch head driver in the screw then tap it sharply with a hammer before trying to turn it. This usually helps to release the screw plus seats the driver a little better.

If You have those short clutch head bits that fits into a drill driver adapter, those work even better when tapped on as they are short and solid and delivers a greater amount of impact to the fastener, unlike a plastic handled screw driver.
