Description

Another industry first from the mechanics at Kansas AirSeeder Service. This air hammer bit is for the heavy duty air hammers that take the larger .498 bit shank. This bit will save you days of work. You don’t even have to remove the row unit to remove or install the main bushings. This driver drives completely through blowing out one bushing and continuing through to push out the next. We recommend setting air pressure above 110 psi as some bushings are harder than others. Remember that these drills sometimes make it harder to push out one way than the other, so if you find it hard pushing them out from one side, try going from the other. Regardless, this air hammer bit it going to get these bushings out. We have videos on our youtube channel “The Air Seeder Mechanic” showing us using these bits and how best to use them. These bits are turned out at our own KAS Machine Shop in Oklahoma, pressed into .498 modified bits. These again will last 5 or more drills if used properly. These bits are made for fast removal and installation of the bushings so are made just smaller than the housing. They will not stop on the housing when pushing them out. The sleeve it comes with can be put on with the chamfer side towards the shaft. This gives the option of installing absolutely flush with the row unit housing. Please watch our videos on how to use this in the fastest most efficient way. Also, these bits get hot. We drive in about 10 sets then dip these in water for a moment to cool them or we let them sit and work on something else for 15 minutes. Our bits have lasted more than a season’s worth of installs which is about 20 drills. They are pressed in and may loosen up after time but still work just as good.
