BURNISHER ROD IS 3/16” DIAMETER BY 3” LONG

If you've ever struggled with turning a hook (or burr) on a scraper, or simply thought there might be a better way, Blackburn Tools and Union Manufacturing Company have designed this patent pending tool for you. Meticulously designed in every detail to be the most versatile burnisher ever, the patent pending Accu-Burr™ is the first and only burnisher you'll need on your bench.

Advantages of the patent pending Accu-Burr™ include:

• Forming a precise and repeatable burr simultaneously on both edges of a scraper.

• No deflection of thin card scrapers, or profile scrapers that are necessarily held high above the vise.

• Will work on any shape, even reaching into concave scraper edges with greater than 3/32" curve radius.

• Works on any hardness of scraper; we've even tested this successfully on HSS steel blades (approximately RC 65).

• Works on any thickness scraper, from 0.010" up to 0.100" thick.

For centuries, the common burnisher has remained largely unchanged. A simple rod of hardened steel held in a handle, their use depended largely on the user's freehand skills. Some mounted that rod in a more sophisticated holder to guide the process, but these, too, had distinct disadvantages.

The heart of the patent pending Accu-Burr™ burnisher is a 3/16" diameter carbide rod with three v-shaped grooves around the middle of the rod. These grooves are precision ground to turn a fine, medium, or coarse (5°, 10°, or 15°, respectively) burr simultaneously on both sides of any prepared scraper edge. Because quality and precision matter greatly for the function of this tool, we use a premium American-made grade of carbide, sourced from and ground by Lakeshore Carbide, a leading carbide tooling manufacturer.

How to use: No burnisher gives better results with less effort. To turn a burr, hold your patent pending Accu-Burr™ carbide burnisher PERPENDICULAR to the prepared scraper edge and centered on either the fine, medium, or coarse groove (the deepest groove is for the coarse burr). Using a moderate downward force 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). Less than 20 pounds of force is required to form a burr; it is less than most people use with a traditional burnisher. 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. It is better to start with light force and gradually increase as needed.

Made in the USA.

Please note: it is possible to break the rod by using excessive force while turning a burr. Though carbide is very hard, it can be brittle. Large handles can also provide enough leverage to snap the rod during use. The handles used on the Accu-Burr burnisher should not exceed the manufacturer’s suggested handle design in either length or diameter. It is also important to closely follow the manufacturer’s Construction and Use Guide for assembly. Failure to do these will result in the voiding of the manufacturer’s warranty. Additionally, dropping an Accu-Burr can result in breaking of the rod. This is not covered under the manufacturer’s warranty.
