Rimmed Finisher Style Reamer for .38 S&W Special Cylinders
The F38SPECC is specifically configured as a rimmed finisher-style reamer to fit .38 S&W Special revolver cylinders: Brownells Schweiz+2Brownells Österreich+2
Cartridge: .38 S&W Special
Application: Cylinder (revolver) – guided by the exit diameter of the cylinder
Style: Rimmed finisher reamer
Clymer marks cylinder reamers like this one so you know the pilot is sized correctly for cylinder work, not barrel work. For revolver cylinders, the pilot must be close to bullet diameter, because it’s guided by the cylinder throat rather than the barrel bore. Clymer Tool+1
Professional-Grade M-7 High-Speed Steel Construction
Like all Clymer pistol chambering reamers, the F38SPECC is made from top-quality M-7 high-speed steel, chosen for its durability and edge retention: Brownells Schweiz+2Brownells Iberica+2
Material: M-7 HSS – hardened and drawn for long life
Designed as a precision tool for professional gunsmiths
Fully guaranteed when properly used and cared for
This premium steel helps the reamer cut smoothly and resist wear over many cylinders, making it a solid investment for both busy shops and serious hobbyists.
Finish Reamer – Full-Dimension Chamber & Throat
Within the Clymer line, pistol chambering reamers are offered as Roughers and Finishers. The F38SPECC is a Finisher: Brownells Sverige+2Brownells Norge+2
Roughers (sold separately) are .010" smaller in diameter, do not cut the throat, and are used when many chambers will be cut to save wear on the finisher.
The Finisher reamer cuts the chamber to final diameter and also cuts the throat.
If you’re only cutting a few .38 Special cylinders, Clymer explicitly notes that “a Finish Reamer is all you need.” That makes F38SPECC a perfect standalone tool for small shops and one-off custom jobs. Brownells Sverige+1
Geometry Designed for Accurate, Concentric Chambers
Clymer’s pistol chambering reamers, including the F38SPECC, are designed with shop-proven geometry to ensure smooth, accurate cutting: Brownells Sverige+2Clymer Tool+2
Six right-hand cutting, straight flutes – stable cutting, efficient chip removal
Solid pilot sized for cylinder exit diameter – keeps the tool properly centered in the chamber
Integral throat – throat angle and diameter are built into the reamer for a smooth bullet transition into the forcing cone
Shank: Typically 7/16" round shank with a 3/8" square drive on pistol reamers (.22 RF models excepted)
This geometry helps minimize chatter, produce a fine surface finish, and keep chambers uniform from hole to hole, which is critical for accuracy and reliable extraction.
Made to SAAMI Specifications

For gunsmiths, that means less guessing and more confidence that every cylinder you cut will perform as intended.
