Spiral Flute Long Forcing Cone Reamer - Gauge 10 Hex Size 1/2''''

Lengthening the forcing cone area decreases pellet deformation and felt recoil for a dramatic improvement in pattern density, shooting comfort and overall shotgun performance. Custom-made reamers with five, spiral flutes increase the cutting surface area for a smooth, chatter-free cut on all types of barrel steel. Do not use on chrome lined bores. Hex-drive shank allows the use of a standard square drive socket and T-handle. Mfg: Brownells SPECS: Tool steel, five flute, spiral cut, 6'''' (15cm) long, 1'''' (2.5cm) long hex section.
