Built from M-7 High-Speed Steel for Long Service Life

Exceptional wear resistance when cutting hardened or tough barrel steels
Long edge life, even across multiple chambering jobs when properly lubricated and maintained
Dimensional stability and strength for consistent chamber geometry

Optimized Geometry – Solid Pilot & Integral Throat
The F22KHOR Rimmed Finisher Style Reamer is purpose-built for .22 K Hornet rimmed rifle cartridges and features: Brownells UK
Right-hand cutting with straight flutes – classic, proven geometry for smooth chambering cuts
A solid pilot to help keep the reamer aligned in the bore and minimize chatter
An integral throat, so the chamber neck and throat are cut in a single operation for consistent bullet alignment and jump
This design helps you produce true, concentric SAAMI-style chambers capable of outstanding accuracy when paired with quality barrels and ammunition.
7/16" Round Shank with 3/8" Square Drive
For secure mounting in standard gunsmithing setups, the RIMMED & BELTED RIFLE CHAMBERING REAMERS F22KHOR uses a robust shank configuration: Brownells UK+1
7/16" round shank – sized for common lathe chucks and reamer holders used in rifle chambering
3/8" square drive – allows engagement with suitable drive tools for controlled, positive rotation
(.22 rimfire reamers in this series use a ¼" round shank, but the F22KHOR is a centerfire .22 K Hornet reamer and follows the heavier 7/16" pattern.) Brownells UK+2Brownells Deutschland+2
This shank layout is ideal for serious shop use, ensuring the reamer can be mounted securely and driven smoothly during precision chambering work.

Series-wide highlights:
Made in the USA
Ground to SAAMI specifications for accurate, repeatable chamber dimensions Brownells Schweiz+1
Offered in Rougher and Finisher styles – roughers run about .010" under final diameter and are used to save wear on the finisher when many chambers must be cut, while a finisher alone is sufficient for a limited number of chambers Brownells Schweiz+1
For F22KHOR, you’re getting the finisher reamer – the tool responsible for that final, critical cut that defines chamber quality.
Ideal for Custom .22 K Hornet Builds & Rechambering
