- Precision Carbide Burnisher with Multiple Grooves: Features a 1/4" diameter carbide rod with three precision-shaped V-grooves at 5°, 10°, and 15° angles, enabling users to produce fine, medium, or heavy hooks for various woodworking tasks.
- Versatile Compatibility: Suitable for use with any size and shape of card scraper, accommodating thicknesses ranging from 0.010” to 0.100”, including high-speed steel versions with a hardness of RC 65. Can handle concave profiles as tight as 3/16” radius.
- Effortless and Consistent Burr Creation: Allows for the creation of precise and consistent burrs on both sides of the scraper edge in a single pass, requiring minimal effort and skill. Self-centering design ensures uniform results with each use.
- Easy-to-Use Design: Simple usage instructions involve filing and honing the scraper edges, securing the scraper in a vise, and drawing the Accu-Burr along the length of the edge with light, even pressure. Accommodates multiple passes for refreshing the burr without frequent re-filing and re-honing.
- Flexible Handle Options: Available in two versions—3” long unhandled rod or the "Junior" version with solid brass handles—for user preference. Offers options for DIY handle creation using compression fittings or Union Manufacturing solid brass ferrules, providing flexibility and cost-effectiveness.
The Patent Pending Accu-Burr Carbide Burnisher is a game changer when it comes to turning precise, consistent, and effective hooks (or burrs) on cabinet scrapers. No burnisher will produce better results with less effort and less skill. Guaranteed. This completely new type of burnisher is a collaboration of Blackburn Tools, Union Manufacturing and Lakeshore Carbide. The heart of the Accu-Burr is a 1/4" diameter carbide rod with three precision shaped V-grooves of slightly differing angles (5, 10, and 15) ground in the center of the rod. These grooves create burrs on both sides of any scraper edge in a single pass. The Accu-Burr will turn a precise and consistent hook on: any size and shape card scraper, it can turn burrs in concave profiles as tight as 3/16” radius any thickness card scraper from as thin as 0.010” up to 0.100” thick any hardness scraper, even High-Speed Steel versions with a hardness of RC 65 thin and profiled scrapers that are held high in a vise that would normally deflect and pose difficulties with a traditional rod burnisher How to use: Prepare your scraper by filing and honing the edges and faces. Secure your scraper in a vise. Hold your Accu-Burr carbide burnisher perpendicular to the scraper edge and centered on either the fine, medium, or coarse groove (the deepest groove is for the coarse burr). Applying light even downward pressure on the burnisher, draw it firmly and smoothly along the length of the prepared scraper edge (a drop of oil on the burnisher will make this action even smoother). The Accu-Burr is self-centering and will draw out a burr on both sides in a single motion. This burnishing will raise a burr that can be barely felt with your finger; if no burr is felt, repeat as needed, but with increasing force, until a nearly imperceptible burr is formed along the entire length of the scraper. A burr can be refreshed 2-3 times by taking an additional pass or two with the Accu-Burr before the edge will need to be refiled and rehoned.
