CXS-05TH075MM-5115R 1025 is an ultra-small shank internal coolant grooving boring bar belonging to CXS series, specially designed for micro small inner hole shallow grooving, internal cutoff and tiny bore profiling processing. Equipped with φ5mm slim round shank and built-in central through-coolant channel, the maximum grooving depth reaches 0.75mm, matched with 5115 series narrow-width grooving inserts; R-type right-hand cutting structure fits most standard CNC lathe clamping seats. The tool body adopts 1025 high-toughness quenched alloy steel, effectively solving the breakage problem of thin small shanks during micro machining, widely applied for precision micro parts thin-wall internal grooving of stainless steel, carbon steel and alloy steel.

• Ultra-slim φ5mm round shank design, suitable for ultra-small aperture internal grooving inaccessible to standard boring bars
• Built-in through-coolant channel, direct cooling to cutting edge to reduce heat and improve insert service life
• 1025 high-toughness hardened alloy steel tool body, strong anti-break performance for thin shank heavy shallow grooving
• Max 0.75mm shallow depth specification, ideal for thin-wall micro part precision narrow groove processing
• Right-hand standard cutting structure, easy installation and clamping on common CNC lathe tool posts
• Precise insert positioning slot, stable clamping for 5115 series grooving inserts with high repeat positioning accuracy
• Compact overall structure, low vibration during low-feed micro grooving, superior workpiece surface finish

• 304/316 stainless steel, mild carbon steel, alloy structural steel, brass, aluminum alloy, thin-wall precision metal parts
