Purpose-Built Throater Handle for .22 Caliber Work
The THT12 is listed by Clymer and distributors as the “Reamer Handle Throater / .22 Handle”, designed around .223–.224 caliber applications. LG Outdoors Website
This dedicated throater handle is ideal for:
.22 caliber throating reamers used to tune leade and freebore
Fine throat adjustments on .223 Rem, .22-250, and other .22 centerfire barrels (where appropriate)
Situations where a full-size chamber handle is overkill, and you want something compact and precise
By matching the handle to the job, Clymer lets you get right up on the workpiece and “feel” the cut as you dial in the last few thousandths.
Made from Premium M-7 High-Speed Steel
Like Clymer’s other reamer handles, the THT12 Throater/.22 T-Handle is manufactured from high-quality M-7 high-speed steel, not soft generic stock. European Brownells listings emphasize that these handles are:
“Hergestellt … aus hochwertigem M-7 Hochgeschwindigkeitsstahl… Präzisionswerkzeuge für den professionellen Büchsenmacher… bieten bei richtiger Pflege eine lebenslange Nutzung. Vollständig garantiert. Hergestellt in USA.” Brownells Österreich+1
What that means for you:
Exceptional strength and toughness under hand torque
Excellent wear resistance, even with frequent use and cutting oils
Long-term dimensional stability, so the drive interface stays tight and accurate
This is a tool built to live on a professional gunsmith’s bench for decades, not a disposable accessory.
Compact T-Handle Design for Maximum Feel & Control
Throating is all about feel—you’re rarely hogging material; you’re creeping up on a final dimension. The THT12 T-handle gives you exactly the kind of tactile feedback that job requires:
Balanced T-handle layout distributes torque evenly between both hands
Allows you to sense cutting pressure and chip load as you advance the throater
Compact size keeps you close to the action, ideal for delicate finishing cuts
Simple, straight design that’s comfortable in gloved or bare hands
Compared to big tap handles or improvised wrenches, this reamer handle is purpose-built for fine, controlled hand work—especially when you’re “just kissing” the throat to tune bullet jump.

Custom barrel installations where you’re matching a specific bullet or seating depth
Accuracy-focused builds in .223/.224 using match bullets and tight chambers
Blueprinting and tuning on precision varmint, competition, and long-range rigs (where .22 centerfire cartridges are used)
Shops that want dedicated tooling instead of one-size-fits-all handles
Clymer and distributor descriptions consistently categorize this handle as a precision tool for the professional gunsmith, not a hobby gadget. Brownells Österreich+1
