Diamond Truing Dressing Tool BC1
The Norton 66260195009 is a single-point diamond tool rated BC quality with one carat weight. It is built for truing and dressing aluminum oxide and silicon carbide grinding wheels up to 21 inches in diameter. Machinists and tool-room technicians use it to restore wheel profile and cutting sharpness.
Thermals noise and power draw
As a non-powered hand tool, it produces no operational noise, draws no electricity and generates no heat of its own. The only thermal load comes from the grinding process it services. A maximum infeed of .0015 inch and traverse speeds between 8 and 10 meters per minute keep friction low during normal dressing passes.
Sustained load behaviour
The diamond point is non-resettable, so the tool must be replaced once the tip wears beyond the 90-degree included angle. Under continuous traverse at the upper speed limit the single point maintains form longer than softer dressers, but prolonged heavy infeed will accelerate wear and eventually require a new tool.

Questions about this item
How do I set the traverse speed correctly for the BC1 tool on my grinder?
Set the traverse speed between 8 m/min and 10 m/min; running slower than 8 m/min causes glazing, while exceeding 10 m/min reduces diamond life and truing accuracy.
When does the diamond point on this BC1 tool need replacement?
The BC1 is non-resettable with a single 1-carat diamond point; replace the entire tool when the point wears flat or the tool can no longer hold the 0.0015 in maximum infeed without vibration.
What is the largest grinding wheel diameter this BC1 tool can true?
The tool is rated for wheels up to 21 in diameter; using it on larger wheels exceeds the specified compatible wheel diameter and can cause uneven dressing or tool damage.
