Hollow-Pro™ hollowing tools are designed by professional woodturner Mike Jackofsky
Manufactured in the USA by the Hunter Tool Company and are available at Craft Supplies USA
These fine turning tools feature a unique “internal swivel tip” with a negative angle built into the tip
These tools have been specifically designed to use the Hunter carbide cutters; the negative angle makes the carbide less aggressive and easier to control. They will remove wood quickly and efficiently from open bowls and hollow vessels. The tools use both #1 and #2 size carbide swivel tip shafts and the M4 powdered metal scraper which is recommended for final finish cuts. The swivel tip shafts and scraper are sold separately. Both the 1/2” and 5/8” tools are designed to fit into any large handle with a 5/8” opening.
NEW!
Hollow-Pro Swivel Tips are now available in #2 and #3 sizes with a negative angle. These tips are less aggressive and are great for finishing cuts and for beginners. The #2 size works well with all the tools and the larger #3 size is perfect for finishing cuts on hollow forms and open bowls, using the 5/8" straight tool.
Available now through Craft Supplies USA
Straight and bent Hollow Pro Tools are available with:
1/2" square shaft (overall length 10")
&
5/8" square shaft (overall length 15")
5/8" Bent Tool with allen wrench and #2 swivel tip shaft with Torx wrench
Notes On Use of Hollow-Pro Tools™
IMPORTANT: The tool rest height
should be adjusted so that when the tool is held
straight (parallel to the bed of the lathe) the tip is cutting at the
center line of the turning. For less aggressive cuts, raise
the handle slightly. Avoid lowering the handle, as that will
raise the cutter tip and could result in a very aggressive angle of
cut. Tighten the swivel tips securely with the included allen
wrench. Mike recommends holding the handle against your body and
practicing with the tools on an open bowl before using them on a hollow
vessel.
STRAIGHT TOOLS:
Straight hollowing tools are easier to control and more suitable for turners learning to make hollow vessels. The use of a bent tool is necessary for many hollow form shapes, but requires more experience to master. The Hollow-Pro Tools™ 1⁄2” and 5/8” straight tools are very versatile and efficient tools that can be used to remove wood very quickly and easily from hollow vessels and open bowls. These tools accept both the #1 and #2 size swivel tip shafts, but Mike recommends the #2 size for the larger 5/8” tool.
BENT TOOLS:
All “bent” hollowing tools that are meant to be “hand-held” should only be used with the straight part of the shaft on the tool rest. With Hollow-Pro Tools™ this indicates that the shaft is aligned with the cutter, making the tools easier to control. The tool rest height is particularly important when using bent tools, so make sure the tip is cutting on the center line of the turning and that you are not lowering the handle, which raises the tip to a more aggressive angle. The Hollow-Pro Tools™ 1⁄2” bent tool was designed to hollow vessels up to about 8” in diameter, but is also intended to be used on larger pieces as well. By using the smaller tool to undercut the first portion of larger vessels the tool rest is closer, resulting in a cleaner cut and greater control. The larger Hollow-Pro Tools™ 5/8” bent tool can then be used to continue hollowing pieces up to about 14-15” diameter.
Hollow-Pro™ SCRAPERS
Made from high quality M4 powdered metal, they are sharpened with a 75 degree grind and have been heat treated to HRC 62-64. The scrapers may be resharpened with a diamond hone or light careful grinding. Since all Hollow-Pro Tools™ have a built in negative angle at the tip, when the M4 scrapers are inserted the result is a clean, less aggressive, final finish cut. Mike recommends using the scraper for your last few cuts, when you are close to your final wall thickness.
