Floating reamer holders isolate the reamer from spindle runout, critical for tight chamber tolerances on precision builds.

They also stock core drills for wildcat cartridge development and specialty reaming applications.

Gunsmiths building custom rifles, precision shooters running match-grade chambers, reloaders developing new cartridges, and armorers working with both standard and proprietary designs. Their reamer specs follow SAAMI standards where applicable, with CIP and custom options for specialized work.
