has anyone had success using an air nibbler cutting .040 aluminum..I've tried two different brands and both of them plug up in short order..when they work they cut like butter but once the punch heats up they lock up..just wondering if anybody has found a fix or if I should find a different tool..they work great for cutting tight radiuses and small holes....

try a shot of WD40 every once in a while on the cutter. works great

if the wd-40 doesn't work try some vasoline or mig welder nozzle dip when the bit starts to warm up. both are gels, but with the bit warmed up some it should melt on your cutter nicely.

I use a solid lubricant made for the machining trade. Comes in a stick about 2" diameter, just wipe it on to the aluminum where you will be cutting, and go to town. When it gets hot, it liquifies, works very well. Made by Tap Magic and others. Works real well for porting aluminum heads, also. We call it 'Duck Butter'.

I weld on and build alot of firetrucks, they are mostly aluminum. What we use is cuttin oil called A-9, its a green oil used for maching and cutting aluminum. Its good stuff! I also use it when I am die grinding on alum.

I prefer an air sheer/scissors (don't know what its really called) Got for about $40 from harbor freight + salvage. Nibbler jammed too easily and was hard to cut a straight line...then you have all those sharp "moon" peices that imbed in your shoe soles and get tracked into the house. Just my opinion.

I have a shear also ..but when doing interior and decking work, its hard to cut tight radius with the shears(or hand shears for that matter)..the nibbler can cut a hole about the size of a quarter with no jagged edges like a shears

hey kk17, ever tried vasoline when you're porting an aluminum head or intake manifold? works great there too.
