CoroBore 824 XS New boring concepts

Boring small-diameter holes even at long overhangs has never been easier. Sandvik Coromant is now expanding the fine boring offer with new boring concepts. CoroTurn XS boring bars and the exchangeable-head (EH) system make boring down to 1 mm (0.039 inch) diameter possible, while keeping your tool inventory at a minimum.

Benefits

• Increased accessibility with Coromant Capto and EH modular interfaces in small diameters
• Boring with solid carbide boring bars reduces vibration and increases stability when working with long overhangs
• Boring bars with indexable inserts and diameter adjustability increase tooling flexibility while reducing tool investment and inventory costs

Features

• Fine boring tool with precision diameter adjustment of 2 microns (nonius scale) to obtain tight tolerances of IT6
• Great tooling flexibility: choose from the Coromant Capto^® or the EH system to bore different diameters
• Standard CoroTurn^® XS inserts available from diameter 1 mm (0.039 inch)
• Solid carbide boring bars with standard CoroTurn^® 107 indexable inserts available from diameter 6 mm (0.236 inch)
• Adjustment range for CoroBore^® 824 XS Coromant Capto and Coromant EH adaptors
• C3, shank 04, 06, 08 = 1 mm radially
• C4, shank 10 = 1.5 mm radially

Coromant EH and Coromant Capto: CoroBore 825

Application

• Fine boring of small holes in all materials
• Stable boring at longer overhangs (up to 6 × diameter)
• Better accessibility with small boring head diameters, making it possible to bore in complex components
• Solid carbide shanks provide longer boring depths – up to 6 × diameter

ISO application area

 

​Recommendations

• A conical shank gives best hole quality at long overhangs, regardless of which chuck is used
• For a cylindrical shank the best straightness is generally given by short overhangs
• Choose conical solid carbide for overhangs up to 6 × diameter
• Choose heavy metal shanks for best stability and reduced vibration tendencies at short overhangs
• Choose CoroChuck™ 930 for best stability and production security
