Chamber reamer prices
Prices for reamers made to CIP specifications or SAAMI specification are listed on this page. Prices are based on the size of the base of the corresponding cartridge. For example, a 308 Winchester has a base diameter of 12.03mm so this is a 'Regular' reamer. 'Magnum' reamers (for example, a 300 Win Mag.) are defined as reamers with base diameters greater than 12.5mm and Large reamers (for example, a 50 Browning) as having base diameters larger than 15.5mm.
For non-standard reamers made to your specifications, or changes to the dimensions on standard reamers, there will be a surcharge of £25.
We also keep a number of machined and hardened reamer blanks on the shelf, so if you want a non-standard dimension such as a tight neck or longer throat on a standard reamer, we can normally turn that around within a week.
For reamers which we do not have in stock and have to be made from scratch, we can normally make these within two weeks. Due to the innovative CNC software which we have created, we can very quickly turn a chamber or reamer drawing into the necessary G code for our CNC lathes and milling machines to make the machined reamer blank, and also to create the dxf file so that the hardened reamer can be finish ground .
Carbide reamers, usually used in production barrel chambering, are made to order.
These days, gunsmiths will usually chamber a barrel in a lathe using a reamer holder in the tailstock, so we do not generally put a square end on the back of the shank. If you want a square back end on the shank, please specify this in the order and we will put one on at no extra charge.
Carbide reamers are generally used in production on a CNC lathe, held in a metric collet tool holder. Please specify the shank diameter you want if different from our standard 11.113mm (7/16" or 0.4375")
Pilot bushings and pilot spigots
Our large chamber reamers will generally have a 7.5mm x 12.7mm pilot spigot, which is not a standard used by any other manufacturer, and so pilot bushings will be supplied with the reamer.
