Woodturning Tools
Choose a hollowing tool by its reach
A tool that reaches the center of an open bowl may not pass through a narrow opening to reach the shoulder. Compare the path of the cutting head as well as the shaft length.
Map the path from the opening
Start with the opening and the part of the inside surface you need to reach. Compare straight, curved and swan-neck profiles against that path. Check any clearance or support requirements documented for the exact model.
Check the head and the support
A complete handheld hollower, a bare tool bar and a support rig are different purchases. Confirm what holds the cutter and which parts are included. Use the maker's limits on the tool rest or support system.
Find the replaceable parts before buying
If the cutter is replaceable, note its part number and fastener. A tool family may use different cutter sizes on curved and straight models, so use the code for the specific tool rather than the family name.
