◆ Heavy Metal Solid Bars

• Tool combinations with heavy metal boring bars provide higher rigidity and better vibration damping compared to conventional steel shank tools when machining long bores with a ratio over 5:1.
• Their dense structure and machinability offer higher toughness than carbide.
• Milling chucks are recommended for holding these bars, along with hydraulic chucks.
• Heavy metal bars are available in CKB1, CKB2, CKB3, and CKB4 sizes.

◆ Carbide Solid Bars

• Tool combinations with carbide boring bars provide optimum rigidity for finish machining extremely long bores.
• The carbide bars can be moved axially and clamped to the required length in compact tool holders.
• Hydraulic chuck tool holders are recommended.
• Carbide solid bars are available for CKB1, CKB2, and CKB3 sizes. These solid bars should not be used for heavy roughing.
