OSG M10X1.5 6HXC Machine Tap with 6HX Oversize Medium Tolerance and C Modified Bottoming Short Chamfer for High Precision Internal Thread Tapping

M10*1.5 6HXC OSG is authentic Japanese OSG general-purpose cobalt high-speed steel machine tap, professionally developed for M10*1.5 metric fine pitch internal thread tapping of carbon steel, alloy steel, stainless steel and grey cast iron. Equipped with exclusive 6HX oversize medium thread tolerance and C-type modified bottoming short chamfer, one tap adapts to both blind hole full-thread machining and standard through hole tapping. Adopting wear-resistant TiCN nano coated HSSE cobalt substrate, it matches standard tapping chucks of CNC lathes, machining centers and tapping machines, supports stable low-torque continuous tapping and mild interrupted cutting of uneven scaled blanks. Widely applied in automotive component workshops, hydraulic valve processing plants, general fixture machinery and mold auxiliary thread mass production.

• HSSE cobalt-alloy high-speed steel blank, integral quenching heat treatment, outstanding red hardness, maintains stable hardness above 600°C tapping temperature, avoids cutting edge softening and rapid wear in long-cycle mass production
• 6HX special over-tolerance thread design based on standard 6H, appropriately enlarges thread medium diameter tolerance; after slight tap flank wear, internal thread still meets assembly standard, greatly prolongs single tap service life and reduces tool replacement frequency
• C modified bottoming short chamfer structure, only 2–3 cutting teeth on the front chamfer, can machine complete full thread close to blind hole bottom without excessive idle hole, improves blind hole processing efficiency and reduces material waste
• Nano TiCN multi-layer PVD coating with strong substrate adhesion, excellent high-temperature wear resistance and self-lubricating performance, thoroughly solves chip adhesion, thread burr and surface roughness defects during stainless steel tapping
• Optimized uniform spiral/straight chip flute structure, smooth chip evacuation channel quickly discharges curled metal chips, prevents chip extrusion scratching finished internal thread tooth surface
• Precision Japanese grinding thread profile, strict tooth angle and pitch tolerance control, consistent internal thread dimensional accuracy and surface finish for long continuous batch tapping
• Standard square shank design, compatible with all mainstream tapping chucks, floating tap holders and machine tapping equipment, wide universal clamping adaptability
• Dual-scene universal compatibility, suitable for blind hole deep thread forming and through hole high-speed continuous tapping, simplifies workshop threading tool inventory classification and procurement cost

• Mild carbon steel
• Medium carbon structural steel
• Low alloy structural steel
• 304/316 austenitic stainless steel
• Grey cast iron
• Ductile iron
• Low-hardness pre-hardened mold steel
