Product Description Product Detailed DescriptionThe HSK125A Series Chuck Toolholders represent a comprehensive range of precision clamping solutions engineered exclusively for heavy-duty CNC Vertical Machining Centers (VMCs) and Horizontal Machining Centers (HMCs). Unified by the HSK125A dual-contact taper interface (ISO 1940-1 standard), the series covers multiple functional configurations-including flange milling, shank-tool clamping, and deep-hole drilling-to meet diverse machining needs in automotive manufacturing, mold & die production, and heavy machinery fabrication. Designed for maximum rigidity, minimal runout, and broad compatibility, this series eliminates the need for mixed toolholder interfaces, streamlining inventory and ensuring consistent performance across production lines.Core Series-Wide Advantages(common to all HSK125A models)All toolholders in the HSK125A series share foundational design features that define their heavy-duty precision:HSK125A Dual-Contact InterfaceAdopts 1:10 hollow taper with simultaneous taper + face contact (dual-location), eliminating radial runout (≤0.003mm at 3×D from tool end) and axial play. This ensures stable cutting even under high loads (up to 15kN axial force), critical for deep-slot milling or high-feed drilling.Complies with ISO 1940-1 and DIN 69893 standards, ensuring compatibility with all HSK125A-spindle CNC machines (e.g., Mazak VTC-800, DMG MORI NHX 8000, Haas UMC-1600SS).High-Strength ConstructionMachined from heat-treated 42CrMo alloy steel, quenched and tempered to HRC 45-50 for optimal balance of toughness and wear resistance.Surface treated with black oxide or zinc-nickel plating to resist corrosion from coolants, extending service life by 50% vs. uncoated toolholders.Precision BalancingAll models are balanced to G2.5 standard at 5,000 RPM (some high-speed variants to G1.0 at 8,000 RPM), minimizing spindle vibration and reducing bearing wear in long production runs.Optional Through-CoolantMost configurations (e.g., FMC, MLD) offer integrated 3-5mm diameter coolant channels, directing high-pressure coolant (up to 20 bar) to the cutting edge. This reduces thermal wear on tools (e.g., carbide end mills, drills) and improves chip evacuation-essential for stainless steel or high-temperature alloy machining.HSK125A Series Configuration BreakdownConfigurationModel ExampleCore FunctionKey Application ScenariosFlange Milling (FMB)HSK125A-FMB40-60Secures flange-mounted face mills/shell millsHeavy-duty face milling of engine blocks (40Cr steel), mold bases (P20 steel)Shank Tool Clamping (FMC)HSK125A-FMC40-60Grips shank-type tools (end mills, drills) via collet/setscrewPrecision shoulder milling of gear blanks, deep-hole drilling in cast iron (HT300)Morse Taper Drilling (MLD)HSK125A-MLD20-135Converts HSK125A to Morse taper (e.g., MT4/MT5) for large-diameter drillsDeep-hole drilling (≥20mm diameter) in heavy machinery components (e.g., hydraulic cylinders)High-Precision Collet (ER)HSK125A-ER50-100Clamps small-diameter shank tools (3-20mm) with ER colletsFine finishing of mold cavities, micro-drilling in aerospace partsEach sub-model retains the HSK125A interface's rigidity while adding task-specific features-e.g., FMB flanges have precision-drilled mounting holes for face mills, MLD models include Morse taper sleeves for drill compatibility.Technical Specifications(Series-Wide & Model Specific)ParameterSeries-Wide StandardModel-Specific VariationsTaper InterfaceHSK125A (1:10 hollow taper)/Material42CrMo alloy steel/HardnessHRC 45-50/Radial Runout≤0.003mm (3×D)≤0.002mm for high-precision ER modelsMaximum RPM5,000 RPM (G2.5)8,000 RPM (G1.0) for high-speed variantsOverall Length60-200mm60mm (FMB/FMC), 135-200mm (MLD, long-reach ER)Tool Compatibility/FMB: 80-200mm face mills; FMC: 10-20mm shanks; MLD: MT4/MT5 drillsUser Benefits Inventory Efficiency: A single HSK125A series replaces multiple non-compatible toolholder lines, reducing inventory costs by 30%.Consistent Precision: Dual-contact interface ensures ≤0.003mm runout across all models, improving tool life by 25% and reducing scrap rates.Broad Compatibility: Fits all HSK125A-spindle CNC machines and standard cutting tools (no custom adapters needed).Durability: 42CrMo construction and corrosion-resistant coating withstand 10,000+ clamping cycles-backed by a 12-month warranty against manufacturing defects. Key Application Industries & Use Cases The HSK125A series excels in high-demand industrial scenarios where rigidity and precision are non-negotiable:Automotive Manufacturing: FMB models for face milling engine cylinder heads (S45C steel); FMC models for machining transmission housings (6061 aluminum).Mold & Die Production: ER models for fine finishing of plastic injection mold cavities (P20 steel); MLD models for deep drilling of mold cooling channels.Heavy Machinery: MLD models for drilling large-diameter holes in excavator hydraulic arms (QT600 ductile iron); FMB models for milling structural steel components.Aerospace: High-speed ER variants for micro-milling of titanium alloy (Ti-6Al-4V) brackets, with through-coolant to manage heat.Why Choose Us?"Engineered for Flawless Flat Surfaces" - Trusted by 1,000+ CNC workshops globally.Certifications: ISO 9001 Grade Information MATERIALGRADEISO COATING COMPOSITION COLORSteel PYP9117P10-P20TiCN+α-Al2OYELLOWYP9112P10-P25TiCN+α-Al2OBLACKYP9127P15-P30MT-TiCN+α-Al2OYELLOWYP9122P15-P30MT-TiCN+α-Al2OBLACKYP9132P25-P40MT-TiCN+α-Al2OBLACKYP9115P10-P20TiN+MT-TiCN+Al2O+TinDOUBLE COLORYP9125P15-P30TiN+MT-TiCN+Al2O+TinDOUBLE COLOR GRADEISOCOATING COMPOSITION COLORYG2125P10-P3M15-M30K15-K30TiALNGREY BLACKYG2125BP10-P30M15-M30TiALSiNDARK PURPLEYM2127M10-M30TiALNYELLOWYS6125P10-P30M15-M30TiALNSILVER YM6110M10-M30TiALNDARK PURPLEYM6120M10-M30TiALSiNCOPPERYM6125M10-M30AlCrN+AlCrSiNYELLOW Our Main ProductsCarbide turning insertsTNMG/WNMG/CNMG/DNMG/VNMG/SNMG/CCMT/TCMT/VBMT/DCMTCarbide threading inserts16ER/16IR AG60 AG55 /ISO1.0 1.5 2.0 2.5 TR SAGE API APIRD W ectCarbide grooving insertsMGMN/MRMN/TDC/TDJ/TDT/TDXU/SP/DGN/N123/PENTACarbide milling insertsR390 /APMT/ APKT/BDMT/RCKT/RPMW/RPMT/RDMTHigh feed milling insertsBLMP/LNMU/LOGU/SNMX/ONMU/3PKT/LNMX/WNMU/SDMTAluminum insertsCCGT/DCGT/TCGT/VCGT/GDMA/SEKT/APKTDrilling insertsSPMG/WCMXCermet cutting toolsCCGT/TPGT/WBGT/TNGGToolholdersSER/SNR/MGEHR/L/SPB ect StockOur company has sufficient stock, and we also provide non-standard customised service,different Hardness based on client's requirement.Packaging & ShippingPackaging:Step 1:The product is packed in a plastic box, normally 10 pcs in a box.Step 2: using bubble wraps to package each insert parcel.Step 3: using the paper carton of Thickening and hard with bubble wraps to sealing.Shipping:We use the fastest express (FedEx, TNT, DHL, UPS) to deliver, can deliver to any country within 5-15 days.PaymentT/T / Western Union More About Us FAQ1Q:Who are we?A:We are based in Chengdu, China.
