J-Bridge Intake Port Modification Tool Kit
We've taken the guess work out of selecting the appropriate cutting and grinding tools to undertake your 12A or 13B rotary engine J-bridge intake porting effort.  This j-bridge intake tool kit provides all necessary cutting bits, mandrels, sanding rolls, and grinding tools needed to take on this project. These select tools are the same tools that the Racing Beat technicians use to perform the various intake porting modifications required in development of racing and prototype engines. Selected to provide optimum efficiency for use in your street port intake porting efforts, each cutting tool is top-quality, quick-cutting and can be re-sharpened after extended use. When using a cutting tool you MUST use an appropriate cutting lubricant (i.e. Saw Wax) to prevent damage to the cutting tool.

Tool kit includes:

5 - Carbide cutting bits
3 - Sanding roll mandrels (long, short, split end)
2 - 24" sandpaper strips 
6 - Grinding stones ( cylindrical - 2 each & ball - 4 each)
16 - 1/2" diameter sandpaper rolls (80 & 120 grit - 4 each)
4 - 3/8" diameter sandpaper rolls (80 - 5 each  & 120 grit - 4 each)
2 - 3/8" diameter sandpaper rolls 200 grit
8 - 3/8" diameter sandpaper rolls 220 grit
