The Robert Sorby RS206 Arm Brace Handle is a highly regarded, classic woodturning support system originally conceived by Dennis Stuart and later produced by Robert Sorby. It relies on adapter inserts to fit different tool shank sizes. [1, 2]
The accompanying ¾” and ½” hollowers with carbide cutters are an exact match for the signature hollowing tools manufactured by Trent Bosch Tools. Woodturners frequently combine the ergonomic Sorby arm brace handle with Trent Bosch's high-performance hollowing bars to gain maximum control and vibration dampening over deep vessel turnings.

Tool Verification & Synergy
- The Handle: The Robert Sorby Arm Brace fastens securely against your forearm to absorb rotational torque and counter destructive catches during deep hollowing. [1, 2]
- The Adapter Inserts: Because the Sorby handle has a fixed opening, these sleeves allow it to adapt to smaller or larger tool shanks, seamlessly bridging the gap between different tool brands. [1]
- The Hollowers: Trent Bosch designs dedicated ½” Carbide Hollowing Tools (ideal for depths up to 6") and ¾” Carbide Hollowing Tools(ideal for depths up to 12"). They utilize rotatable, replaceable cup-style carbide cutters that yield clean, sliced wood shavings rather than rough, scraped dust. [1, 2, 3, 4]
