12 Bore rim cutter

12 bore rim cutter

The problems with rim cutters for chambers like the 12 bore is firstly to ensure the cutter stays centred and concentric to the chamber, secondly that the cutter is well supported and thirdly that it does not chatter. Offerings by other reamer manufacturers do not seem to satisfy these requirements well, so we have developed this rim cutter, seen above.

12 bore rim cutter detailThe rim cutter is supported by the pilot which locates in the bore at the front. There is a sliding tapered cylinder which sits in the back of the chamber, so the cutter well supported and yet able to slide freely on the cutting axis. The tolerance and concentricity of the pilot and sliding tapered cylinder ensure the cutter is very well centred to the chamber. Cost is £158.00 including the pilot.
