Carbide Grades - Because a Hard Rod is Good to Find!
Ground Carbide Rod
In order to offer you the best variety of high quality carbide products, we carry blanks from more than one manufacturer. The exact specifications for a given grade may vary slightly from those shown here. For information about any particular products, please ask. We'll be happy to provide more details.
C-1 - (Most commonly used for rotary carbide burs)
C-2 (Most commonly used for 1000's series and SBT-style blanks)
10% Micrograin -- (Our most common carbide rod grade)
12% Ultra-Micrograin - (offers increased hardness for special rod applications)
C-2 for Diamond Coating
In order to offer you the best variety of high quality carbide products, we carry blanks from more than one manufacturer. The exact specifications for a given grade may vary slightly from those shown here. For information about any particular products, please ask. We'll be happy to provide more details.
C-1 - (Most commonly used for rotary carbide burs)
- Hardness: 90.5 Ra
- Strength: 250,00-380,000 psi
- Cobalt Content: 6%
- 0.3%-0.5% each Tantalum and Titanium carbides
- Avg. Grain Size: 3.5 micron
- Characteristics: General purpose grade, excellent wear resistance, more heat resistant than 10% cobalt grades.
C-2 (Most commonly used for 1000's series and SBT-style blanks)
- Hardness: 92.1 Ra
- ISO K20/30
- Strength: 400,000 psi
- Cobalt Content: 6%
- Avg. Grain Size: 1.2 micron
- Characteristics: General purpose grade, excellent wear resistance, more heat resistant than 10% cobalt grades.
10% Micrograin -- (Our most common carbide rod grade)
- Hardness: 92.0 Ra
- Strength: 475,000 psi
- Cobalt Content: 10%
- Avg. Grain Size: .6 micron
- Magnetic Saturation: 130-160
- Characteristics: Extra fine grain for general purpose. Excellent wear resistance, more impact resistant than C-2 grade.
12% Ultra-Micrograin - (offers increased hardness for special rod applications)
- Hardness: 93.0 Ra
- Strength: 580,000 psi
- Cobalt Content: 12%
- Avg. Grain Size: .2 micron
- Characteristics: Ultra fine grain. Outstanding wear resistance, good shock resistance.
- Comment: Ultra-Micrograin has a smaller and more consistent grain size than standard micrograin material. This grain structure tends to provide both longer and more consistent tool life.
C-2 for Diamond Coating
- Hardness: 92.0 Ra
- Strength: 450,000 psi
- Cobalt Content: 6%
- Magnetic Saturation: 120-150 (emu/g)
- Avg. Grain Size: 1.2 micron
- Characteristics: General purpose grade, excellent wear resistance, more heat resistant than 10% cobalt grades. Accepts diamond coating well.
