Reamers, drills and other engineering tools are used for a variety of purposes and their sale is not restricted.
Most reamer manufacturers will, however, produce reamers to customer specifications.
The reamer slowly cuts away material, leaving a chamber capable of accepting a specific cartridge.
Chamber reamers come in two general types - solid pilot reamers and floating pilot reamers.
Given proper care, a reamer can cut 10-15 chambers between sharpening.
These reamers increase the width of the ice channel and reduce friction between the hull and ice.
The hole is then prepared to a precise diameter with a reamer.
After verifying the correct anatomic eyelet pin placement, a 7-mm reamer is used over the pin to drill a tunnel depth of 25 mm.
